China high quality Cross Roller Slewing Bearings with high quality

Cross Roller Slewing Bearings

Cross-roller slewing bearings, their rollers are arranged at 90° to each other at intervals between the inner and outer rings. They can simultaneously bear loads from all directions (such as axial, radial, overturning moment, etc.). Because the rollers are in line contact with the track surface, the elastic deformation of the bearing under heavy load is correspondingly tiny, and the rigidity is high. At the same time, it has mounting holes and sealing accessories or is equipped with teeth on the inner or outer ring to simplify the installation structure.

Crossed roller slewing bearing is also called crossed cylindrical roller slewing bearing. The single-row crossed cylindrical roller slewing bearing consists of 2 rings. It has a compact structure, is lightweight, has high manufacturing precision, small assembly clearance, and requirements for installation accuracy. High. The rollers are arranged in a 1:1 cross, which can simultaneously bear axial force, overturning moment, and large radial force. They are widely used in lifting and transportation, construction machinery, and military products. This bearing pre-interference has high rotation accuracy, supporting rigidity, and the ability to withstand high dynamic loads.

Product parameters

(1) Model parameters of external gear crossed roller slewing bearings

Standard Crossed Roller Bearing

CRB/CRBC: CRB/CRBC standard type is a bearing with the thinnest possible inner and outer rings because the outer ring is split while the internal circle is integrated into the main body. It is used in cases where high rotational accuracy of the inner ring is required.

RU series Crossed Roller Bearing.

RU series: RU particular type is a bearing with an integrated inner- and outer ring. It is used in cases where high rotational accuracy of both the inner- and outer rings is required.

XU Series Crossed Roller Bearing

XU Series: XU particular type is a bearing with an integrated inner and outer ring. It is used in cases where high rotational accuracy of both the inner and outer rings is required.

SX series Crossed Roller Bearing.

SX series: standard type is a bearing similar to an RB standard. A locking ring connects the 2 detachable outer rings.

NRXT series Crossed Roller Bearing

NRXT: NRXT series is a bearing with the thinnest possible inner and outer rings because the outer ring is split while the inner ring is integrated into the main body. It is used in cases where high rotational accuracy of the inner circle is required.
