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 length of the metal LM block and increased the number of load-bearing rollers to achieve an improved static load rating.
For the HRX, in order to achieve an improved basic static load rating, we have extended the length of the metal LM block and increased the number of load-bearing rollers.

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.
The Model HRX is designed to have an equal basic load rating on the LM block for all four directions. (*Four directions: radial, reverse-radial, horizontal) As a result, this model can be used in any orientation, enabling a wide variety of applications.
A contact angle of 45° is used so that the basic load rating is equal in all directions: radial, reverse-radial, and horizontal.
This model is equally suited for use in a horizontal orientation and any other orientation.
Structure of the HRX
The Model HRX features raceways on the sides of the LM rail, which come into contact with the rollers at a 45° angle.
Lineup
The Model HRX comes in six sizes ranging from 25 to 65, and a lineup of four block types is available: C/LC and R/LR.The Model HRX's dimensions conform to world-standard ISO specifications (ISO 12090-1:2011 Rolling Bearings). Only #65R/LR height M differs from ISO dimensions.
