圆柱滚子轴承

滚动体是圆柱滚子的向心滚动轴承。

圆柱滚子轴承内部结构采用滚子呈平行排列，滚子之间装有间隔保持器或者隔离块，

可以防止滚子的倾斜或滚子之间相互摩擦，有效防止了旋转扭矩的增加。

The rolling element is the centripetal rolling bearing of a cylindrical roller.

The internal structure of cylindrical roller bearings adopts rollers arranged in parallel, and there is a spacer or isolation block between the rollers, 

which can prevent the tilt of the rollers or the friction between the rollers, 

effectively preventing the increase of rotating torque.
