Deep Groove Ball Bearing 6800 Series

1. Bearing Material
High carbon chrome bearing steel(Gcr15) is the standard material for bearing ring & rolling elements, also carbon steel & stainless steel will be used upon request. The cages are pressed steel ribbon cages & pressed steel snap cages. For extra-high speed application, synthetic-resin, stainless steel, nylons(Phenolic resins) will be used upon request.
2. Lubrication
Different types of greases can be supplied for shielded & sealed bearings and oil for open bearings
3. Tolerance
YUTONG Bearings can meet tolerance grades from ABEC-1 to ABEC-3 as requested dimension tolerance & runout accurancy.

C2 Group clearance only for bearings over ABEC-3 accurancy.
4. Vibration and Noise
The vibration and noise of bearing in four classes Z1, Z2, Z3 and Z4, It is measured by the instrument of S09-1, For special requirement, it is measured by BVT-1 and classified as V1, V2, and V3, The date are shown tables, different vibration & noise requirement should be menrioned in order.
