Single-row Crossed Roller Bearing

Single-row crossed roller bearing incorporates two rings and is designed with compact construction, light weight, high precision, and small assembling clearance. The rollers are crossed one by one, enabling the slewing bearing to accommodate high axial, radial and tilting moment loads. Single-row crossed roller bearing is suitable for hoisting equipment and other engineering machinery.

The sealing of the slewing bearing, on the one hand, is to prevent the leakage of filled grease, on the other hand, is to prevent the outside dust, impurities and moisture from invading into the exterior of the bearing and affecting its work. The sealing ring of LYJW slewing bearing is made of nitrile rubber material, which is resistant to high temperature and corrosion.

Raceway

Bearing raceway surfaces are quenched, whose quenching hardness is HRC55-62, guaranteeing that its effective hardening depth is qualified.

Toothing

Due to the need to transmit force, slewing bearings usually have teeth on one of the rings. The toothing is generally normalized or quenched and tempered. Depending on the application, the gears can also be full-tooth hardened or single-tooth inductively hardened. Single tooth inductively hardening can be divided into full tooth hardening and tooth foot (flanks and base) hardening.
