       推力圆柱滚子轴承常组合成高刚度轴承配置,可以毫无困难地承受重载荷和振动载荷。这种轴承可以承受单方向很大的轴向载荷,但是不能承受径向载荷,它们没有自动调心能力。

       推力圆柱滚子轴承可以拆分为推力圆柱滚子和保持架组件、轴圈和座圈。

       811系列和812系列推力圆柱滚子轴承由推力圆柱滚子和保持架组件、轴圈和座圈组成,重要的零部件是推力圆柱滚子和保持架组件。保持架:推力圆柱滚子轴承可采用模压玻璃纤维增强型聚酰胺66保持架(表示为:TVPB、TVPB1),机加工轻金属保持架(表示为LPB)或机加工黄铜保持架(表示为:MB、MPB)。

Thrust cylindrical roller bearings are often combined into high-rigidity bearing configurations that can withstand heavy loads and vibration loads without difficulty. This type of bearing can withstand large axial loads in one direction, but cannot withstand radial loads, and they do not have self-aligning capabilities.

Thrust cylindrical roller bearings can be split into thrust cylindrical roller and cage assemblies, shaft washers and seat washers.

811 series and 812 series thrust cylindrical roller bearings consist of thrust cylindrical roller and cage assemblies, shaft washers and seat washers. The important components are thrust cylindrical roller and cage assemblies. Cage: Thrust cylindrical roller bearings can use molded glass fiber reinforced polyamide 66 cages (denoted as: TVPB, TVPB1), machined light metal cages (denoted as LPB) or machined brass cages (denoted as: MB, MPB).
