推力圆柱滚子轴承

产品详细

  推力圆柱滚子轴承属分离型轴承,只能承受单向轴向载荷和轻微冲击,能够限制轴(或外壳)一个方向的轴向位移,因此可用作单向轴向定位。但其承载能力远远大于推力球轴承。滚子滚动时,由于滚子两端线速度不同,使滚子在套圈滚道上不可避免地产生滑动,因此,此类轴承的极限转速较推力球轴承低,通常仅适用于低速运转场合。

  标准设计的推力圆柱滚子轴承采用车制金属实体保持架,根据用户要求,也可采用其它型式或材料的保持架。推力圆锥滚子轴承只能承受单向轴向载荷,能限制轴承单向轴向位移,故可用作单向轴向定位。与推力圆柱滚子轴承相比,承载能力大、相对滑动小,但极限转速较低。

  推力圆柱滚子轴承主要用于重型机床、大功率船用齿轮箱、石油钻机、立式电机等机械中。
