Main structure of thrust ball bearing consist of a row of steel balls and a cage, it belong to separate bearings. It can carry axis load, no radial load,according to different structure, it can carry load in single or double directions. It is suitable for the equipment of low rotate speed.
Except main type of thrust ball bearings,there are some derivative bearings,like thrust ball bearings without cage，thrust spherical ball bearings,thrust four-point contact ball bearings,the thrust ball bearing with inner gear and outside gear, doubleaction thrust ball bearings.
