Full-Ball Type LM Guide, Radial Type, SR Model

Full-Ball Type LM Guide, Radial Type, SR Model

THK

THK

A type with a compact structure that has a low cross-section height and is resilient against loads in the radial direction. More advantageous than HSR when incurring loads in the radial direction (longevity, precision, rigidity, etc.).

[Features]
· Circulates the ball row using the end plate that is assembled in the LM block when the ball rotates the rotating side with four rows that have been precision ground into the LM block and LM rail.
· The ball will not fall out even if the LM block is removed from the LM rail because it is held by a holding plate.
· Has a low cross-section height, and the LM block has been designed with a high rigidity, which allows for highly precise and consistent linear motion.
· A compact type with a low cross-sectional height, which is ideal for horizontal guide parts for ball contact structures that are strong against loads in the radial direction.
· This is a self-aligning type that can easily absorb error in the level precision and the degree of parallelism for the two shafts, which is capable of highly precise and smooth movements.
· The retainer part on each of the ball rows can obtain rolling motions with limited sound because of the balls being designed to smoothly circulate using the guiding part on the end plate.
· It is possible to maintain precision of long periods of time, have excellent abrasion resistance and limited differential slipping even when there is a preload or uneven loads.
· LM block, LM rail, and LM rail are all compatible with stainless steel.
