Engine/Bearing/773531-773550 BALL BEARING SINGLE THRUST, WITH FLAT SEAT

中文品名：单推力滚珠轴承，平底座

Series 51200, With Flat Seat

Thrust ball bearings are composed of washer-like bearing rings with raceway grooves for the balls.  The ring attached to the shaft is called the inner ring or shaft washer while that attached to the housing is called the outer ring or housing washer.  In double direction thrust ball bearings, there are three rings with the central one being fixed to the shaft.  Single direction and double direction thrust ball bearings can support thrust loads in one or both directions respectively.  There are also thrust ball bearings with an aligning seat washer beneath the outer ring in order to compensate for shaft misalignment or mounting errors.  Pressed-steel cages are usually used in the smaller bearings and machined cages are generally used in the larger ones. 

推力球轴承由类似垫圈的轴承圈和滚道槽组成。连接到轴上的环称为内环或轴垫圈，而连接到外壳上的环称为外环或外壳垫圈。在双向推力球轴承中，有三个套圈，中间的一个固定在轴上。单向推力球轴承和双向推力球轴承可分别承受单向或双向推力载荷。也有推力球轴承，在外圈下面有一个调心座圈，以补偿轴不对中或安装误差。较小的轴承通常使用压钢保持架，较大的轴承通常使用机械加工的保持架。
