Rexroth Roller Rail systems have been especially designed for machine tools and industrial robots requiring compact, roller bearing linear motion guideways. They are available in various accuracy classes with extremely high load capacity and high rigidity.
These space-saving assemblies available in 5 common sizes (25mm to 65mm) afford the same high load capacities in all four major planes of load application.

The Miniature version of the Rexroth Ball Rail System has been developed specifically for the precision engineering sector, i.e. for the production of optical or electronic data processing devices, where rolling-element linear motion guideways of extremely compact dimensions and high load capacity are required. The linear motion guideways have equal load capacities in all four directions of load application.

Features:

• High load capacity in all directions including moments about all axes utilizing the largest possible ball diameter.
• Lubrication access from front face and/or side ports, dependent on size.
• All parts made of corrosion and acid resistant material similar to DIN 17230/EN 10088.

Rexroth’s eLINE range of ball rail systems was developed for applications where high rigidity and accuracy are frequently not the most important considerations, especially for light machinery and for handling and positioning movements where the main emphasis is on economy and durability. Made of wrought aluminum alloy with ball tracks of hardened antifriction bearing steel, the runner blocks and guide rails are characterized by their low weight, compact design, and equal load bearing capacity in all four main directions of loading.

Special features of the new eLINE Ball Rail Systems:

• Available in the three most common sizes to DIN 645-1
• Structural design allows for much greater parallelism and height offsets of the mounting bases
• Can be mounted even on unmachined mounting surfaces, depending on the application
• Especially compact, lightweight design; 60% weight saving versus steel versions
• Much higher corrosion resistance than steel versions
• Two rows of especially large-diameter balls make this guide less sensitive to dirt while offering higher torsional stiffness
• Runner blocks initially greased in-factory, therefore provided with long-term lubrication
• Available in two accuracy classes and two preload classes
• Ball retainers in the runner blocks allow them to be removed from the rail without any loss of balls
• Optional lube units can be mounted at each end to prolong lubrication intervals still further, often reaching lube-for-life, and provide end sealing action
• Guide rails with reference edge on both sides
• All accuracy classes can be combined with one another
• Interchangeability allows individual stocking of runner blocks and guide rails
• Same connection dimensions as steel ball rail systems
