Project Description
The Inch R Series Ball Bearings are radial ball bearings with inch dimensions available from 0.5″ to 1.5″ bore size.
The Structure of inch R series ball bearings is a type of non separable deep groove bearing, and allows an axial thrust loads in addition to radial loads.
- bearing material: chrome steel(GCr15/SAE52100) and stainless steel(440/316/304)
- Seals: open, ZZ(metal shields), 2RS(rubber seals)
- tolerance: P0(ABCE-1), P6(ABCE-3), P5(ABCE-5), P4(ABEC-7), P2(ABCE-9)
- clerance: C0(normal), C2, C3
- noise: Z(normal), Z1, Z2, Z3.
- vibration: V(normal), V1, V2, V3.
