产品简介：
是可分离型轴承，只能承受轴向载荷。单向轴承只能承受一个方向的轴向载荷，双向轴承能承受两个方向的交变轴向载荷。推力球轴承在工作中必须加以轴向予紧。他们主要适用于车床顶心、汽车离合器、减速机等。双向推力角接触球轴承适用于机床主轴，单向推力角接触球轴承适用于丝杠支承。
This type of bearings is separable , which can only carry axial load . The single direction bearings of them can only carry axial load in one direction , while the double an carry alternating axial load in either direction . Before using they have to be preloaded. The thrust ball bearings are used in lathe centers , auto clutches, reducers and so on . The double direction angular contact thrust ball bearings are suitable for machine tool spindles , while the single are used to support ball screws .
