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, to ensure ultra-high rigidity, rollers with low elastic deformation and optimized diameter and length are used as the rolling elements. 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.

Features
Structure and Features of the 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, to ensure ultra-high rigidity, rollers with low elastic deformation and optimized diameter and length are used as the rolling elements. 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 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 reduced running sound.


Smooth Motion
● Rolling Resistance Data
Evenly spaced and aligned rollers circulate, minimizing rolling resistance fluctuations and achieving smooth and stable motion.

Conditions
- Feeding speed10 mm/s
- Applied loadno load (one block)

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 achieving long-term maintenance-free operation.

Radial Rigidity


Reverse-Radial Rigidity


Horizontal Rigidity

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.
