Product Description

Product Definition & Features:

Slewing bearings are the core components that enable rotational motion. Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear.

Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components.

The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination and in any direction.
 

Single Row Four Point Contact Ball Slewing Bearings

Single-row four-point contact ball slewing bearings consist of two seat rings, featuring a compact structure and light weight.
The steel balls make four-point contact with the arc-shaped raceway, enabling the bearing to simultaneously withstand axial forces, radial forces, and overturning moments.
It is suitable for use in engineering machinery such as rotary conveyors, welding manipulators, medium and small-sized cranes, and excavators.

Single Row Crossed Roller Slewing Bearings

Single-row crossed roller slewing bearings consist of two seat rings, featuring a compact structure, light weight, high manufacturing precision, small assembly clearance, and high requirements for installation accuracy.
The rollers are arranged in a 1:1 crossed pattern, enabling them to simultaneously withstand axial forces, overturning moments, and large radial forces.
They are widely used in lifting and transportation equipment, construction machinery.

Double Row Ball Slewing Bearing

Double row ball slewing bearing has three seat rings; the steel ball and the spacing block can be directly arranged into the upper and lower races, and two rows of upper and lower steel balls with different diameters are fitted according to the stress condition.
This kind of open assembly is very convenient, for the upper and lower bearing raceway arc angles are 90°, which can bear large axial forces and tilting moments. When the radial force is greater than 0.1 times the axial force, the raceway needs to be specially designed.
Double row different ball slewing bearing's axial and radial sizes are relatively large and solid in structure, so they are especially suitable for the medium diameter tower cranes, truck-mounted cranes, etc., and loading and unloading machinery.

Three Row Roller Slewing Bearings

The three-row roller slewing bearing features three seat rings, with separate upper, lower, and radial raceways, enabling precise determination of the load on each row of rollers.
It can simultaneously withstand various loads and is the product with the highest load-bearing capacity among the four types.
It has large shaft and radial dimensions and a robust structure. It is particularly suitable for heavy machinery requiring a large diameter, such as bucket wheel excavators, wheel cranes, ship cranes, steel ladle rotators, and large-tonnage truck cranes.

Thin Section Slewing bearings

Light slewing bearings have the same structural form as ordinary slewing bearings but are lighter in weight, more compact in structure, and thinner in design.
They are widely used in fields such as food machinery, filling machinery, and environmental protection machinery.

Flanged Slewing Bearing

Flanged slewing bearings are specialized rotary bearings designed to withstand high axial, radial, and moment loads while facilitating smooth and precise rotation in various applications.
They are characterized by a flange on their outer or inner ring, facilitating easy mounting and, in some cases, providing greater stiffness.
Flanged slewing bearings are widely used across different industries, including construction, wind turbines, heavy machinery, and crane systems.
