SKF deep groove ball bearing is the most representative rolling bearing with wide range of uses. It is suitable for high speed or even high speed operation, and it is very durable without frequent maintenance. SKF deep groove ball bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and easy to achieve high manufacturing accuracy. Dimensions and forms vary widely. It is the most widely used type of bearings in machinery industry for its applications in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries. It is mainly subjected to radial load and can also bear a certain amount of axial load.
