Profile: ZZ Bearing (Shanghai) Co., Ltd specializes in manufacturing of ball bearings and roller bearings. we offer cover various kinds of common bearings such as spherical roller bearing, cylindrical roller bearing, tapered roller bearing, deep groove ball bearing, and angular contact ball bearings. The precision bearings we produce are widely used in the industries of metallurgy, chemistry, coal, papermaking, cement building material and mechanical equipment. Spherical roller bearings are designed with two row rollers running between an inner ring of two raceways and an outer ring with a spherical raceway. This allows these bearings to support both an axial and radial load, and the high radial load capacity ensures the spherical roller bearings are ideal for heavy load or impact load conditions.
