Caged Roller LM Guide

The Caged Roller LM Guide is a roller guide that achieves low friction, smooth motion, and long-term maintenance-free operation by using a roller cage. In addition, rollers with optimized lengths and diameters have been utilized as the rolling elements in order to minimize elastic deformation and achieve ultra-high rigidity. Furthermore, the lines of rollers are placed at a contact angle of 45° so that the same rated load is applied in all (radial, reverse-radial, and horizontal) directions.

Structure and Features of the Caged Roller LM Guide

Caged Roller LM Guide is a roller guide that achieves low-friction, smooth motion and long-term maintenance-free operation by using a roller cage. In addition, to ensure ultra-high rigidity, rollers with low elastic deformation are used as the rolling elements and the roller diameter and the roller length are optimized.Furthermore, the lines of rollers are placed at a contact angle of 45° so that the same rated load is applied in all (radial, reverse and lateral) directions.

Advantages of the Caged Roller Technology

Evenly arranged rollers circulate in a way that limits the front-to-back and side-to-side movements of the rollers, preventing the rollers from skewing and minimizing rolling resistance fluctuations. The end result is smooth and stable motion.
The absence of friction between rollers and the retention of lubrication in grease pockets enable long-term maintenance-free operation.
The absence of friction between rollers achieves low heat generation and superbly high speed.
The absence of roller-to-roller collision ensures low noise and acceptable running sound.

Long-term Maintenance-free Operation

● High-speed Durability Test Data

Use of a roller cage eliminates friction between rollers, minimizes heat generation and increases grease retention, thus to achieve long-term maintenance-free operation.
