Deep groove Ball Bearing is bearing the most common type. The basic model consists of a deep groove ball bearing outer ring, an inner ring, a ball and a set to keep structure as deep groove ball bearing type code 0. Deep groove ball bearings are mainly used for pure radial loads, but also to support radial and axial load. When the only pure radial loads, the contact angle is zero. Deep groove ball bearing friction coefficient is small, speed is also high, especially in very high speed load conditions in the axial direction, deep groove ball bearings. Deep groove ball bearing structure is simple, easy to reach compared with other types of manufacturing high precision, so easily into a series of mass production, the use of very common. For high speed or high speed operation, and very durable, without regular maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low cost, easy to achieve high manufacturing precision.

A great variety of types and designs are known, the manifolds of the bearings is justified by their various purpose of application, each type of bearing has a certain characteristic technical properties, Hardware bearings have the following advantages compared with the plain bearings:
1) Shield / closure: Open bearing, Z, ZZ, RS, 2RS
2) Snap ring: N, NR
3) Tolerance codes: ABEC-1, ABEC-3, ABEC-5, ABEC-7
4) Vibration level codes: V4, V3, V2, V1
5) Internal clearance codes: C2, C3, C4, C5
6) Material: GCr15, AISI52100, AISI440C, AISI304, AISI316, ceramic
7) Retainer: PTFE, nylon, PEEK or stainless steel
