Slewing Bearings

The four-point contact gearless slewing bearing is a large-scale bearing with a special structure that can withstand large axial loads, radial loads and overturning moments.Single-row four-point contact ball slewing bearings are generally composed of two rings. They have a compact structure and are lightweight.

Cross-roller type internal gear slewing bearings are generally composed of four parts: inner ring, outer ring, rolling element, and separator. it can carry the axial load and radial load at the same time.The ring gear with internal or external teeth can be selected according to different applications.The cross-roller type slewing bearings are widely used in lifting, transportation, and construction machinery.

External geared slewing bearings, as precision transmission components, comprise four key units: inner ring, outer ring, rolling elements, and separators. Designed for combined axial/radial load-bearing, they maintain structural consistency across subtypes (e.g., single-row cross-roller types feature dual-ring frames). Precision machining enables compact, lightweight designs while supporting multi-load capabilities (axial, overturning moment, large radial). Configurable inner/outer gear rings enhance installation adaptability. Widely used in hoisting, transportation, and construction machinery.

This abstract summarizes key features of four-point contact slewing bearings: The large-scale, specialized internal gear type integrates support, rotation, torque transmission, and fixation functions, designed to simultaneously withstand high axial/radial loads and overturning moments. Single-row ball variants, typically with two-ring structures, feature compact, lightweight designs; their steel balls maintain precise four-point contact with curved raceways, enabling concurrent load-bearing of multi-directional forces to optimize performance in demanding rotational applications.
