For tapered roller large end and sliding friction between the inner wall, the speed limit is often lower than the same size cylindrical roller bearings.
因圆锥滚子大端与内圈挡边之间滑动摩擦，其极限转速往往低于同尺寸的圆柱滚子轴承。

The influence of the pile type and the friction angle of the contact surface on the limit bearing capacity of the piles and the composite foundation is discussed with an example.
