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 bearing have various types in structure, beside open type bearings, shield or seals at both side can also be provided.

Characteristic of deep groove ball bearing:
1. Seal form: open style, Z, ZZ, RS, 2RS, 2RZ
2. Bearing stop ring: N,NR 
3. Class of precision: ABEC-1, ABEC-3, ABEC-5, ABEC-7 
4. Vibration rank: V1, V2, V3, V4 
5. Noise rank: Z1,Z2,Z3,Z4.
6. Internal Clearance code: C0, C2, C3, C4, C5
7. Bearing material: bearing steel (9Cr18), stainless steel (AISI440C, AISI304, and AISI316), ceramics
8. Cage: stainless steel, PTFE, nylon
9. Bearing rings and ball hardness: 59 - 63HRC
Explanation:
  Z represents that one-side of the deep groove ball bearing is mental dust cover, and ZZ represents that both sides are mental dust cover.
  RS represents that one-side of the deep groove ball bearing is non-touch sealed, and 2RS represents that both sides are non-touch sealed.
  RZ represents that one-side of the deep groove ball bearing is contact seales, and 2RZ represents that both sides are contact sealed.
