Double row tapered roller bearing
ID : 80 - 570 mm, OD : 140 - 750 mm WAFANGDIAN ROLLING BEARING MAKING CO.,LTD

Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the centerline of the bearing. Due to this design feature, rollers move along the center of the raceway surfaces. The tapered rollers are guided by the compound force of the inner and outer raceway surfaces which keep them pressed up against the large rib on the inner ring. A large veriety of these bearings, including single, double, and four row arrangements, are in use both in metric and inch series.
Back to back arrangement (with two outer rings) and face to face arrangement (with two inner rings) types are both available, and they have been adjusted ao that each type's internal clearance values are fixed. Therefore, only parts with identical manufacturing numbers can be used and they must be assembled according to their code numbers.
