Tapered roller bearing major in application to support combined load (radial load and axial load) which inclines to radial load .It generally not suit to sustain axial load solely. Under the radial loading forces, it will produce additional axial forces. The axial load ability of the bearing is determined by the contact angle .The bigger the contact angle, the heavier the axial load capacity. Tapered roller bearing is combined by separate bearing and the inner ring with rollers and separators. And the outer ring can be installed separately. During the process of mounting and using we can regulate its radial clearance,axial clearance and also can install with pre-interference .We company can produce all types of single, double and four row tapered roller bearing .It has the typical features of easy mounting and dismounting and regulating clearance .It can be widely used in all the various trades and occupations.
