Type SSR with Caged BallTM Technology
LM Guide type SSR is equipped with four rows of balls optimally configured for the highest load carrying
capacity in radial direction. This product also incorporates the revolutionary Caged BallTM design that
eliminates wear caused by friction between balls, thus improving the service life of the grease, achieving
low noise and pleasing running sound, and increasing high-speed performance. In addition, the ball cage
significantly improves the smoothness of motion in vertical applications by uniformly arranging the balls
within the block regardless of its orientation. The blocks are equipped with polyurethane seals on both
ends and the bottom to help keep lubricants in and dirt and debris out.
