mobile crane bearing Crossed roller bearing

Crossed roller bearing assembly points and quality measures

Thin-walled cross roller bearings according to its structure, the assembly stage needs to grasp the bearing clearance control, rotary accuracy Taper roller bearings‍ and stability of 3 points, cross roller bearings belong to special bearings with high precision, is mainly used in CNC machine, robot arm, as well as medical and military equipment, which are double row roller in a 45 degree tilt angle roll cross distribution channel, can maintain high rigidity on the roller and raceway contact line, but also because of a 45 degree tilt angle raceway can be uniformly load of axial and radial bearing, perfect overturning or torsional moment; in addition, cross roller bearings with negative clearance design and pre tight, can high rigidity bearing rotary bearing‍ guarantee (compared with traditional models, rigid increase 3~4 times) and high precision, cross roller bearings precision Luoyang Boying bearing is in P5 above, basic accuracy of P4, P2.
