Product Description

Compact design with low cross-sectional height and ideal for horizontal guides.
[Features]
· 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.
· Self-aligning type that can easily absorb error in the level accuracy and the degree of parallelism for the 2 shafts, which is capable of highly accurate and smooth movements.
· The retainer part on each of the ball rows can obtain rolling motions with limited sound because the balls are designed for smooth circulation using the guiding part on the end plate.
· Accuracy is possible to be maintained for long periods of time, has excellent abrasion-resistance and limited differential slipping even when there is a preload or uneven load.
· LM block, LM rail, and ball are all compatible with stainless steel.
· 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.
