THK HSR25 HSR25LB Linear Guide Slide Block HSR25LB1SS

Linear Slider THK LM Rail Block SSR20XW SSR20XW1UU(GK) are a range of machine parts that are indispensable for reducing linear motion friction in the positioning mechanisms of machinery.We supply a large range of products including the linear way and linear motion rail guiding systems, and a ball spline-based shaft guiding system. Available sizes range from the world’s smallest track rail at just 1 mm wide, to a very large version which provides high rigidity and high-load capacity. The Caged Ball LM Guide can realize long service life and long-term maintenance-free operation and improve the work environment. Caged Ball LM Guide GK Series include three types; Models SHS, SSR and SRS, which are made available.

With the Caged Ball LM Guide, balls circulate being retained by the ball cage, thus to eliminate metallic contact between the balls. When balls enter or leave the loaded area of the LM block, the ball circulation part of the unloaded area of the LM block is formed with resin, which prevents metallic contact between the balls and LM block. Therefore, the Caged Ball LM Guide reduces noise and improves the quality of the operation sound. In addition, the grease retained in the ball circulation path and the ball cage (grease pocket) forms a very thin oil fi lm on the ball surface by being caught by rotation of the balls. This constantly keeps good the lubrication condition of the contact surface between each ball and the ball cage.
