The ZZ single row cross roller slewing bearing provides a reliable rotation solution for excavators, truck cranes, drilling rigs, and tunneling machines. Its rollers are arranged in a 90° cross pattern, allowing the bearing to handle axial, radial, and tilting moment loads simultaneously. This design ensures high rigidity, stable rotation, and minimal deformation, making it ideal for heavy machinery operating under demanding conditions.
Crane slewing bearings, also known as slew bearings or slew bearings, are critical components in the design of cranes and other heavy machinery that require rotation about a central axis. The main function of the slewing bearing is to support the upper structure of the crane (such as the jib and cab) and make it rotate smoothly.
Single row cross roller slewing bearing consists of two rings, compact structure, light weight, small clearance, so high precision is required.Roller adopts 1:1 cross arrangement, can bear axial force, tilt moment and relatively large radial force.It is widely used on lifting, transportation, construction machinery and military products.
