Full Ceramic Ball Bearing for Hand Spiner
1. Introduction to Deep Groove Ball Bearings:
Deep groove ball bearings are one of the most commonly used rolling bearings. They are widely applied in various industries. The raceway grooves on both the inner and outer rings have a slightly larger radius than that of the balls. These bearings can handle both radial and axial loads in either direction. Due to their low friction, they are ideal for high-speed applications where energy efficiency is crucial. In addition to open bearings, they often come with steel shields or rubber seals on one or both sides, pre-lubricated with grease. Snap rings may also be used on the periphery, and pressed steel cages are typically the most common type.
2. Features of Deep Groove Ball Bearings:
- Shield / Closure: Open, Z, ZZ, RS, 2RS, 2RZ
- Ball Bearings with Snap Ring: N, NR
- Tolerance: ABEC-1, ABEC-3, ABEC-5, ABEC-7
- Vibration Level: V4, V3, V2, V1
- Radial Play: C0, C2, C3, C4
- Material: GCR15
3. Versions of Deep Groove Ball Bearings:
- With one or two side rubber seals: RS, 2RS
- With one or two side metal shields: Z, ZZ (2Z)
- With snap ring groove in the outer ring: N
