Product Description

Descriptions
deep groove ball bearings are non-separable and require little attention or maintenance in service, capable of operating at high speeds and are widely used radial bearings. The inner and outer ring of single row deep groove ball bearings have a deep groove raceway. The bearings are mainly used to carry radial loads and a part of axial loads in two directions. This kind of bearing can carry much heavy axial loads after the increase of radial clearance, thus, it can take the place of high speed angular contact ball bearings.  Deep groove ball bearings have various types in structure, besides open type bearings, shields or seals at both sides can also be provided.

Features
The bearings are the most typical rolling bearings with extensive applications. The raceways in both of the rings are in arc groove form, which can carry radial and axial load in double directions. They can be applied in situations where high-rotating speed and low noise and low vibration are required.

Applications
All kinds of motors, toys, medical equipment, electric vehicles, sports and office equipment.

Types
Basic type; With snap ring groove on the outer ring (-N); With one shield (-Z) on one side or two shields (-2Z) on both sides; With one seal (-RS) on one side or two seals (-2RS) on both sides.
