详细介绍
电机，俗称“马达”，是指依据电磁感应定律实现电能的转换或传递的一种电磁装置。
电机轴承又名电动机轴承或者马达轴承，是专门应用于电动机或者马达上的一种轴承。电机使用的
轴承是一个支撑轴的零件，它可以引导轴的旋转，也可以承受轴上空转的部件，轴承的概念很宽泛。电机常用的轴承有四种类型，即滚动轴承、滑动轴承、关节轴承和含油轴承。zui常见的电机轴承是滚动轴承，即有滚动体的轴承。滑动轴承泛指没有滚动体的轴承，即作滑行运动的轴承。
中小型电机多数采用滚动轴承。目前大中型号电机也采用滚动轴承。小型电机两端轴承，采用滚珠轴承（深沟球轴承）。中型电机在负载端采用滚柱轴承（一般用于高负载工况），非负载端采用滚珠轴承（但也有相反情况，如1050kW电机）。滚动轴承采用润滑脂润滑，但也有用润滑油润滑的。
