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.
1. 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.
2. The absence of friction between rollers and the retention of lubrication in grease pockets enable long-term maintenance-free operation.
3. The absence of friction between rollers achieves low heat generation and superbly high speed.
4. The absence of roller-to-roller collision ensures low noise and acceptable running sound.
Rolling Resistance Data: Evenly spaced and aligned rollers circulate, minimizing rolling resistance fluctuations and achieving smooth and stable motion.

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.

Rigidity is measured with the two axes placed in parallel and one of the axes not fixed with a bolt in order not to apply a moment. |
