INA Linear

Roller monorail guidance systems

Linear recirculating roller bearing and guideway assemblies RUE are, due to the use of cylindrical rollers, the INA monorail guidance systems with the highest load carrying capacity and rigidity. They comprise at least one carriage with a full complement roller system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the upper and lower faces of the carriage and closing plugs to close off the fixing holes in the guideway.

The carriage and guideway of a linear recirculating roller bearing and guideway assembly are matched to each other as a standard system due to their closely toleranced preload. It may be possible, after consultation, to use carriages and guideways in different combinations.

Linear recirculating roller bearing and guideway assemblies are suitable for accelerations up to 100 m/s2, speeds up to 180 m/min and operating temperatures from –10 °C to +100 °C. They are used in applications with long unlimited stroke lengths, high and very high loads and high to very high rigidity.

The units are also available in a design with optimised noise to X-life quality.

Track roller guidance systems

Track roller guidance systems are linear guidance systems that can be compiled according to a modular concept for a wide variety of applications. Due to their lightweight construction, they are highly suitable for use in handling systems. They are particularly characterised by quiet running, high traverse speeds, long displacement distances and the modular concept.

Carriages

Track roller guidance systems comprise one or more aluminium carriages, profiled track rollers and a straight or curved guideway. Carriages are available as hollow section carriages, open carriages, compact carriages and bogie type carriages for curved, oval and circular guidance systems.

Guideways

Guideways consist of an aluminium rail with shafts made from rolling bearing steel rolled into the sides. The guideways are available in many different designs, e.g. guideways with a solid profile, hollow section guideways, flat guideways, guideways with a slot etc. Selection depends on the puropse to which the track roller guidance system will be put.


Shaft guidance systems

Shaft guidance systems or ball-based or plain linear guidance systems for various areas of use and applications. Linear ball bearings are available as a light range, compact range and heavy range. Mating tracks can be solid shafts, hollow shafts or supported shaft and rail units.

The range is rounded off by a large selection of linear ball bearing and housing units and linear plain bearing and housing units. In this case, the linear ball bearings or linear plain bearings are supplied already mounted in ready-to-fit housings.

A large number of shafts (with or without machined features), shaft and support rail units and comprehensive accessories allow a broad spectrum of applications.


Miniature linear plain guidance systems

Miniature linear plain guidance systems are ready-to-fit, maintenance-free guidance systems. They have good sliding characteristics, are suitable for dry running, have adjustable clearance and are highly resistant to chemical influences. In terms of design space, miniature plain guidance systems have the same mounting dimensions as miniature linear recirculating ball bearing and guideway assemblies. The units are produced in various carriage sizes and guideway lengths, giving cost-effective designs.

Miniature linear plain guidance systems are linear locating bearings with at least one carriage. They can support forces from all directions – apart from the direction of motion – and moments about all axes, operate largely free from stick-slip, have low wear and are insensitive to contamination.


Ball monorail guidance systems

Six-row linear recirculating ball bearing and guideway assemblies

Six-row linear recirculating ball bearing and guideway assemblies KUSE are the ball-based guidance systems with the highest load carrying capacity and rigidity. They comprise at least one carriage with a full complement ball system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the lower face of the carriage and plastic closing plugs.

Linear recirculating ball bearing and guideway assemblies KUSE are suitable for accelerations up to 150 m/s2, speeds up to 300 m/min and operating temperatures from –10 °C to +100 °C. They are used in applications with long unlimited stroke lengths, high and very high loads and high to very high rigidity.

Four-row linear recirculating ball bearing and guideway assemblies

Four-row linear recirculating ball bearing and guideway assemblies KUVE are the most versatile and comprehensive range of monorails from INA. These units comprise at least one carriage with a full complement ball system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the upper and lower faces of the carriage and plastic closing plugs.

Linear recirculating ball bearing and guideway assemblies KUVE are suitable for accelerations up to 150 m/s2, speeds up to 300 m/min and operating temperatures from –10 °C to +100 °C. They are used in applications with long unlimited stroke lengths, high loads, high rigidity and low friction.

The units comprise at least one carriage with a full complement ball system, a guideway, integrated elastic wipers on the end faces of the carriage, sealing strips on the lower face of the carriage and plastic closing plugs.

The linear recirculating ball bearing and guideway assemblies are suitable for accelerations up to 150 m/s2, speeds up to 180 m/min and operating temperatures from –10 °C to +100 °C. They are used in applications with long unlimited stroke lengths, moderate loads, moderate rigidity and low friction.


Miniature ball monorail guidance systems

Two-row miniature linear recirculating ball bearing and guideway assemblies

These guidance systems are preloaded linear locating bearings for limited and unlimited stroke lengths. These have moderate load carrying capacity and moderate to high moment load carrying capacity.

Due to the modular concept, guideways and carriages can be interchanged within one interchangeability and accuracy class. This gives easier fitting of guidance systems, easier sourcing of replacement parts and allows very economical stockholding.

The saddle plates and guideways are corrosion-resistant. Seals on the end faces of the carriages protect the rolling element system against contamination. The carriages are greased and can be relubricated. The guideways and carriages are also available in a wide version.

Four-row miniature linear recirculating ball bearing and guideway assemblies

Four-row miniature linear recirculating ball bearing and guideway assemblies are ready-to-fit guidance systems for unlimited stroke lengths. They have high to very high load carrying capacity and rigidity.

The saddle plates and guideways are corrosion-resistant. Seals on the end faces of the carriages protect the rolling element system against contamination. Due to the lubricant reservoir, the relubrication intervals can be extended.

The carriages are greased and can be relubricated.


Linear ball bearing units

Linear guidance systems with linear recirculating ball bearing units comprise ball bearing units, carriages and guideways. They allow large support distances, have adjustable clearance and are to standard accuracy class G3.

The full complement bearing units run on one or both sides of the guideways and, despite their small dimensions, have high load carrying capacity. If the bearing units are screw mounted in carriages, together with the guideways they form four-row linear recirculating ball bearing and guideway assemblies. The ball bearing units are sealed on all sides by the wipers on the end faces and on the sealing strips which form a gap seal in conjunction with the guideway. Linear recirculating ball bearing units can be relubricated.

The carriages comprise an anodised aluminium body and two linear recirculating ball bearing units. The carriage has two T-slots for fixing to the adjacent construction. The clearance can be adjusted by means of three screws on the side of the carriage; the screws press on the back of the bearing unit.

The guideways are available with raceways on one or both sides. They are made from hardened steel and ground on all sides.


Linear recirculating bearings

The linear roller bearings are available in a design in which the cylindrical rollers are separated from each other by spacers, a full complement version and an angled version element. The design with spacers runs particularly smoothly and quietly and is sealed on its end faces. Full complement linear roller bearings are suitable for high temperatures, speeds and accelerations. Angled elements are particularly suitable, due to the 90° arrangement of two linear roller bearings, for closed arrangements. This design is sealed on all sides.


Guideways

Due to their high precision, the guideways in conjunction with the linear roller bearings give high precision linear guidance systems. They are made from through hardened rolling bearing steel, have precision ground raceways and are available as a single piece up to the maximum length. Longer guideways are made up from matched sections. The guideways are supplied in grades Q2, Q6 and Q10.


Miniature cage guidance systems

Miniature carriage units

Miniature carriage units with cylindrical roller flat cages are corrosion-resistant, ready-to-fit cage guidance systems for limited stroke lengths. They have a high load carrying capacity, high rigidity and high accuracy whilst requiring very little space. Due to their compact design, they can often be used to replace guidance systems that require significantly more space. The units are produced in numerous carriage and guideway lengths, giving cost-effective designs.

Miniature carriage units are linear locating bearings. They can support forces from all directions – apart from the direction of motion – and moments about all axes, are more rigid than linear recirculating ball bearing and guideway assemblies and run very smoothly and accurately.

The units are particularly suitable for short stroke lengths, low-friction movements, oscillating movements and high loads with high rigidity. Their preferred areas of use include medical equipment, electrical engineering, robotics and laboratory equipment as well as applications under clean room conditions.

Miniature linear guidance sets

Miniature linear guidance sets with cylindrical roller flat cages are corrosion-resistant, ready-to-fit locating bearings for limited stroke lengths and are preloaded once fitted. These linear guidance systems have high load carrying capacity, high rigidity and high accuracy whilst requiring very little space. Since the distance between the guidance elements can be varied in design, the elements can be easily matched to predetermined adjacent constructions. The sets are supplied in many different lengths for specific applications.

The sets are particularly suitable for short stroke lengths, low-friction movements, oscillating movements and high loads with high rigidity.


Linear actuators

The linear actuators are integrated modular systems containing all the components required for operation.

The guidance systems in these linear actuators are based on linear ball bearing and guideway assemblies of series KUE, KUVE or KUSE or on track roller guidance systems of series LF or plain guidance systems. These are driven by means of a ball screw drive, toothed belt or direct drive (linear motor).


Linear tables

Linear tables are used where larger masses are to be moved in one or more axes. Due to the large distances between support points, these linear tables are also capable of supporting high torques. The guidance systems used are linear ball bearings or linear recirculating ball bearing and guideway assemblies.

Linear tables are available without drive or with ball screw drive, trapezoidal lead screw drive or direct drive.

The range of driven linear units is complemented by controllers, motors and gearboxes which are specifically matched to each other for optimum performance.


M/V guideways with angled flat cage

The basic design comprises the M/V guideway pair and angled flat cages containing needle rollers or cylindrical rollers and is a linear locating bearing. The guideways are supplied in grades Q2, Q6 and Q10.

The cages are made from metal or plastic. Metal cages are suitable for more demanding conditions such as high acceleration, high temperatures and where the ends of the cage are exposed at some point in operation. Plastic cages are particularly economical for simple operating conditions.

Accessories include end pieces for the guideways and wipers to protect the raceways against contamination.


ML/V guideways with adjusting gib and angled flat cage

The basic design comprises the ML/V guideway pair with an adjusting gib and angled needle roller flat cages. These guidance systems are preloaded using the gib; the gib applies the preload uniformly over the whole length of the guideway. The pitch of the gib surface is 1,5%. When the gib is moved by 1 mm, the height changes by 15 µm. The guideways are supplied in grades Q6 and Q10.

The cages used are double row angled needle roller flat cages made from metal or plastic.

M/V guideways with integral toothed rack and angled flat cage

The basic design comprises the M/V guideway pair with an integral toothed rack and angled needle roller flat cages with an integral gear. This variant is used where there is a risk of cage creep, for example in designs with non-uniform rigidity in the guidance area or where the cage does not regularly move to the end positions. The guideways are supplied in grades Q2, Q6 and Q10.

The cages are made from metal, are of double row design and are subject to positive control by the integral gear.


M guideways with plain sliding layer and V guideways

These guidance systems comprise M guideways with a plain sliding layer and V guideways as a mating track. They are used particularly for supporting static or pulsating loads, where lubrication is not possible or only initial lubrication can be provided or where an increased friction level is required in order to provide damping. The guidance systems are also suitable for oil or grease lubrication and have the same mounting dimensions as M/V guideways with flat cages. The guideways are supplied in grades Q6 and Q10.


J/S guideways with needle roller flat cage

These guidance systems comprise J and S guideways separated by needle roller flat cages. They are used as non-locating bearings and for limited stroke lengths.

The guideways are supplied in high and flat versions. The cages made from metal or plastic and are of single or double row design.


Counterstay system with needle roller and cylindrical roller flat cages

This counterstay system is a linear locating/non-locating bearing unit. Due to the subdivision into locating and non-locating bearing arrangements, the system is not distorted by thermal expansion. The locating bearing system comprises M/V guideways and the non-locating bearing system J/S guideways. Needle and cylindrical roller flat cages are arranged between the guideways. The guidance system is preloaded by an L-shaped counterstay. The guideways are supplied in grade Q2.

The counterstay system is used where guidance systems must have high accuracy with extremely high rigidity and load carrying capacity and the adjacent construction must not be distorted by preload forces or thermal expansion. It has the highest accuracy of any rolling element linear guidance system, is particularly low-friction and very easy to fit, requiring no adjustment work after mounting.
