THK球保持器型LM滚动导轨径向型SSR型：SSR15XW、SSR20XW、SSR25XW、SSR30XW、SSR35XW、SSR15XV、SSR20XV、SSR25XV、SSR15XWM、SSR20XWM、SSR25XWM、SSR30XWM、SSR15XVM、SSR20XVM、SSR25XVM、SSR15XTB、SSR20XTB、SSR25XTB
SSR结构与特长：钢球沿着LM轨道和LM滑块上经精密研磨加工而成的4列滚动面进行滚动，通过球保持器与组装在LM滑块上的端盖板，使钢球列作循环运动。
因为采用截面高度低的紧凑设计，并具有在径向方向上承重能力强的钢球接触构造，所以适合于水平安装下使用。
