Product descriptions from the supplier
China slewing bearing manufacturer
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.
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.
Slewing bearing is also called rotary bearing. Some people also call it: slewing bearing and slewing bearing. English names are slewing bearing, slewing ring bearing, turntable bearing, and slewing ring.
It is an important transmission part of the machine that needs to make relative rotary motion between two objects and bear axial force, radial force, and overturning moment at the same time.
WIER slewing rings have been widely used in ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, wind power, industrial machinery, and other industries.
WIER manufactures standard and customized slewing bearings in various designs, with outside diameters from 0.1 to 18 m to meet the demands of particular applications.

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, and military products.
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.
