Heavy-Duty Internal-Geared Crossed Roller Slewing Bearings for Port Cranes

Cross-roller-type internal gear slewing ring bearings are generally composed of four parts: inner ring, outer ring, rolling element, and separator. As the core component adopts slewing bearing, it can carry the axial load and radial load at the same time. Although there are many types of crossed roller type slewing bearings, their structures are the same. The single-row cross roller type slewing bearing is composed of two rings, featuring a compact structure, lightweight design, and high manufacturing precision. It can simultaneously carry axial loads, overturning moments, and large radial loads. The ring gear with internal or external teeth can be selected according to different applications. it also features easy installation and usage. The cross-roller type slewing bearings are widely used in lifting, transportation, and construction machinery.
