4-Way Equal Load Roller-Type LM Guide HRX

LM Guide suitable for ultra-high rigidity and ultra-heavy loads


Feature 1: Ultra-High Rigidity and Ultra-Heavy Loads

The HRX is an LM Guide that uses rollers as a rolling element for higher rigidity. Also, compared to our existing roller products, we have extended the overall length of the LM block and increased the number of load-bearing rollers to achieve improved static load rating.

Feature 2: 4-Way Equal Load

On the HRX, each row of rollers is arranged at a contact angle of 45° so that the LM block receives an equal load rating in all directions (radial, reverse radial, and horizontal directions), ensuring high rigidity in all directions.

4-way Equal Load Type


This model is equally suited for use in a horizontal orientation and any other orientation.



Feature 3: LM Blocks and LM Rails Available for Individual Sale

The HRX lineup features interchangeable products that can meet specifications by freely combining LM blocks and LM rails of the same model number.
