NKX,NKX Z系列组合轴承
滚针组合轴承
Combined Needle Roller And Thrust Ball Bearings
NKX
NKX…Z 系列
此组合式轴承除承受径向负荷外可承受单向轴向重负荷。
组合轴承是我司具有特色的一款产品,具有精度高,使用寿合长等特点.目前我司生产的组合轴承已于国内多个主机厂家配套并远销国外. 组合式滚针轴承是由一个向心滚针轴承和一个推力 轴承 相结合 ,因此能够承受径向和轴向负荷。 组合式滚针轴承在很小的径向空间里对固定端 轴承 配置进行定位。...而其它类型的固定端 轴承 占空间太大的场合,这些 轴承 特别有用 .
TN=塑料保持架,允许工作温度:120°C连续;180°C短期。
