What is SKF Deep Groove Ball Bearing - Ball and roller bearing

SKF deep groove ball bearing is an instrument device with open and double-sided sealing ring. The sealed bearing has a groove for sealing ring or dust cover on the outer ring. It is suitable for high speed Running.

The basic types of SKF deep groove ball bearings are open type, double-sided with seal ring or double-sided with dust cover type, which is in production. Sealed bearings have grooves on the outer ring that can be fitted with seals or dust caps. The groove can also be supplied as an open bearing.


The basic types of SKF single row deep groove ball bearings use normal tolerances. As long as the user needs, we can also provide bearings with tighter manufacturing tolerances.

Bearing clearance

The basic type of SKF single row deep groove ball bearings uses a basic clearance set. Bearings with larger clearances are available on request.


The basic type of SKF deep groove ball bearings without the retainer suffix in the model is fitted with a steel stamping cage. The deep groove ball bearing with the suffix M in the model has a steel ball-guided brass solid cage.


Due to the limited self-aligning ability of SKF deep groove ball bearings, the concentricity of the bearing installation is required. The poor concentricity will affect the smoothness of the operation and increase the stress of the bearing, thus shortening the service life of the bearing. In order to keep the additional stress on the bearing within the permissible range, SKF deep groove ball bearings can only allow a small deflection angle, which also depends on the load.

Allowable speed

SKF bearings In some cases, the reference speed may exceed the limit speed. Specific operating conditions are considered by determining the amount of heat generated at the maximum allowable operating speed.


SKF deep groove ball bearings are the most representative rolling bearings and are used in a wide range of applications. Suitable for high speeds and even high speeds, it is extremely durable and requires no maintenance. 

SKF deep groove ball bearings have small friction coefficient, high speed limit, simple structure, low manufacturing cost and easy to achieve high manufacturing precision. 

Dimensional range and form are varied, and it is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery. It is the most widely used type of bearing in the machinery industry. 

It is mainly subjected to radial loads and can also withstand a certain amount of axial load.
