Bearing quality appearance

1, the bearing parts are not allowed cracks, sharp edges, burrs and rust; raceways are not allowed on the channel processing traces; inner and outer rings, balls Face ultra-fine grain should be uniform, not allowed to have scratches, bumps;
2, the bearing parts with surface grinding lines should be consistent with the rules, does not allow a spiral pattern, chatter, yin and yang face and grinding marks, does not allow support printing and significant measurement traces, does not allow bump hurt and obvious color differences.
3, the parts of the surface oxide are not allowed. Chamfering rings, inner diameter, outer diameter required lighting process.
4, the bearing ring parts by pickling, the work surface should not have burned, with the surface should not have been visible burns pickling without affecting hardness testing.
5, the assembly chamfer.
a. assembly chamfer dimensions, chamfered shape should be consistent with our product drawings requirements.
b. chamfered surface, no rust and bump hurt.
6, ball
Ball appearance quality standards should be consistent JB/T10861 standards.
7, cage
Exterior surfaces should be smooth, no glitches, no bumps, no rust and obvious color difference, does not allow bruise contusion, deformation and trachoma and other cosmetic defects.
