Double row tapered roller bearing
wafangdian quanhua bearing manufacturing

The outer race and the inner race of the Tapered Roller Bearing are provided with conical raceway, and conical rollers are mounted on among raceways. If the conical surface is extended, it will converge on one point of the bearing axis. Tapered Roller Bearing is mainly used to be subject to radial and axial combination load in which the radial load is major load. Axial load capacity of the bearing is determined by contact angle. The larger the contact angle, the greater the axial load capacity. The Tapered Roller Bearing is separate bearing. The inner race provided with rollers and holder composes the inner component, which can be separately mounted with the outer race.

This type of bearing can limit one side axial displacement of shaft or housing, and does not allow shaft to incline relative to housing bore. Under the effect of radial load, additional axial force will be generated. So the outer race and the inner race are generally mounted opposite to ends in the two supports of the bearing.

This type of bearing is mainly applied on front wheel and rear wheel of cars, transmission, differential mechanism, shaft pinion, machine tool main shaft, construction machinery, large-sized agricultural machinery, mechanical reduction gear of railway car and rolling mill journal speed reducer.
