Four 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.

The performance of this type of bearing is almost identical with double-row Tapered Roller Bearing, but the bearing can be subject to larger radial load than double-row Tapered Roller Bearing. Its limit speed is a little lower, and it is mainly applied on heavy-duty machine such as rolling mill etc.
