|
|
LM Stroke
The LM Stroke is a linear guide of a type with limited strokes that can provide rolling guidance for rotational and reciprocating motion. With a very small frictional coefficient, the LM Stroke provides a compact, highly precise guiding mechanism at an inexpensive price.

|
|
|
Cross Roller Guide
The Cross Roller Guide is a limited stroke linear guide that has precision rollers orthogonalized alternately. This product provides rigid yet supple linear motion and is particularly suitable for linear guidance where high rigidity and supple movement is demanded.
|
|
|
|
|
Linear Ball Slide
The Linear Ball Slide is a lightweight, compact, limited stroke linear guide unit that operates with very low sliding resistance. It excels in high-speed responsive performance due to its very small frictional factor and low inertia.

|
LM Guide Actuator
The LM Guide Actuator is a compact actuator with high rigidity and high precision that has an integrated LM Guide with a ball screw. Reductions in the number of parts and design man-hours can be realised by adopting the LM Guide Actuator.
|
|
|
|
|
Ball Splines
The Ball Spline is a rolling guide spline bearing. This is an innovative product with a ball rolling on a groove connected to the shaft, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.

|
|
|
|
Cross Roller Table
The Cross Roller Table is a compact, high-precision, high-rigidity, limited linear guide unit with built-in cross roller guide. Easily installed with bolts, this product provides a high accuracy linear guiding mechanism.
|
|
|
|
|
LM Roller
The LM Roller is a compact linear guide with high load performance and a mallet type roller able to make infinite circular motions. This product is optimally applicable to machines required for high positioning accuracy, repeatability and rigidity.
|
|
|
|
|
Slide Pack
The Slide Pack is an inexpensive linear guide configured with the press-formed slider and roll-formed rails. It provides lightweight, compact and supple linear motion
|
|
|
|
|
Ball Screws
The Ball Screw is a high-efficiency feed screw with the ball making a rolling motion between the screw axis and the nut. Compared with a conventional sliding screw, this product has drive torque of one-third or less, making it most suitable for saving drive motor power.
|
|
|
|
|
Lead Screw Nut
The Screw Nut is a sliding feed nut compatible with the standards for a 30-degree trapezoidal screw thread. Formed by die-casting special bearing alloy of superb abrasion resistance, it is an inexpensive high precision product.
|
|
|
|
|
Change Nut
The Change Nut is a sliding feed screw of 45° lead angle not easily available from machining. Its large lead angle is best suited to acquiring a quick traverse mechanism at a low revolution rate.
|
|
|
|
|
Flat Roller
The LM Roller is a compact linear guide with high load performance and a mallet type roller able to make infinite circular motions. This product is optimally applicable to machines required for high positioning accuracy, repeatability and rigidity.
|
|
|
|
|
Slide Rail
The Slide Rail is a low-priced limited-type linear guide made of steel plate precision-formed by rolling. Thin, compact and easy to install, this product is suitable for linear guides for various applications.
|
|
|
|
|
Precision Linear Pack
The Precision Linear Pack is a superbly thin and lightweight linear guide. It is most suitable for precision measuring devices, semiconductor manufacturing and inspection equipment, and other applications where accurate linear motion is essential.
