Single-Row Tapered Roller Bearings ( LL575349/LL575310)

Demension: 539.75×635×50.8mm , Weight: 27kg.

SHAPE LOCATION TOLERANCE SHOULD BE TO CURRENT STANDARD;

Single-row tapered roller bearings
primarily carry combined loads which is main in radial,and tapered roller bearings with large tapered angles (27°- 30°)primarily carry combined loads which is main in axial but not pure axial loads. These bearings can limit axial displacement of shafts or housings in one direction. The inner and outer rings can be mounted rspectively as separable structure, the outer rings are interchangeable, and they are easy to be mounted and dismounted. The radial and axial clearance can be adjusted during mounting or working, and also can be interference mounted to increase stiffness. The clearance has great influence on bearing performance. If the clearance was too small, the temperature will be high; but if it was too much, the vibration will be increased and running accuracy will be difficult to ensure. The bearings will be damaged in both cases above. Therefore, the clearance must be adjusted during mounting or working. In order to prevent stress concentration between rollers and raceway to lead to bearing damaged in early period, the obliquity between shafts and housings is not permitted while mounting.

Tapered roller bearings
are widely used in real axle hubs of automotives, large machine tool spindles, large power decelerators, roller wheels of feedways, etc.

TS (Pressed Steel)

This is the most basic and most widely used type of tapered roller bearing.It consists of two main separable parts: the inner race assembly and the outer race.It is typically mounted in opposing pairson a shaft.
