Product Details

Deep groove ball bearings are particularly versatile.They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from VCD in many designs, variants and sizes.

VCD produced 6201 and 6202 deep groove ball bearings(Z3V3 class) are widely used in different types of ceiling fans.Now we have established supplying relations with many fans producers,especially for India markets.Every month we ship large quantity there.

Bearing vibration and noise level can be divided into 4 levels: Z1, Z2, Z3 and Z4. We can detect by S0910-1 instrument. According to the special requirement, we can use BVT-1 detection, and be divided into the V1, V2, V3 and V4.Specific data are listed below. Customer’s order should be indicated the vibration and nosie level requirements.
