Product descriptions from the supplier
China slewing bearing manufacturer
Slewing bearings serve as fundamental elements for allowing spinning movement. These bearings consist of an inner and outer ring, with one typically featuring a gear assembly.
Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components.
The inner and outer rings, together with the rolling components and retainers or spacers, are engineered to handle forces applied individually or jointly, regardless of orientation.
Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components.
The inner and outer rings, together with the rolling components and retainers or spacers, are engineered to handle forces applied individually or jointly, regardless of orientation.
Often referred to as a rotary bearing, the slewing bearing is alternatively known as a slewing bearing or slewing bearing. In English, it is commonly termed slewing bearing, slewing ring bearing, turntable bearing, or slewing ring.
A critical component in machinery that enables rotational movement between two elements and simultaneously withstands axial, radial, and overturning loads
WIER slewing rings are extensively applied across marine systems, construction equipment, light manufacturing tools, metal processing machines, medical devices, wind energy systems, heavy industrial systems, and various other sectors.
WIER produces both standard and bespoke slewing bearings in multiple configurations, offering outer diameters ranging from 0.1 to 18 meters to suit specific application needs.

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 are composed of two ring supports, offering a compact design, low mass, precise production, minimal fit tolerance, and strict demands on installation precision.
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
A double-row ball slewing bearing features three support rings; the balls and spacer block are positioned directly within the upper and lower raceways, with separate upper and lower ball sets of varying sizes installed based on load distribution.
This open configuration is highly practical due to the 90° arc angles of the upper and lower bearing raceways, enabling it to handle significant axial loads and tilting torques. If the radial load exceeds 0.1 times the axial load, the raceway must undergo special engineering.
Double-row variable ball slewing bearings feature substantial axial and radial dimensions with a robust design, making them ideal for medium-diameter tower cranes, mobile cranes, and material handling equipment.
Three Row Roller Slewing Bearings
This three-row roller slewing bearing includes three seat rings, each having distinct upper, lower, and radial raceways, allowing accurate measurement of the load carried by each roller row.
It can simultaneously withstand various loads and is the product with the highest load-bearing capacity among the four types.
Features a substantial shaft and wide radial reach with a strong, durable build. Ideal for heavy-duty equipment needing a big diameter, including bucket wheel excavators, wheel cranes, ship cranes, steel ladle turners, and heavy-load truck cranes.
Thin Section Slewing bearings
Light slewing bearings share the same basic design as standard slewing bearings but feature reduced mass, a more condensed build, and a thinner profile.
They are widely used in fields such as food machinery, filling machinery, and environmental protection machinery.
Flanged Slewing Bearing
Flanged slewing bearings are advanced rotational components engineered to handle substantial axial, radial, and torque forces, enabling accurate and seamless spinning across diverse industrial uses.
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.

Step1.Forgings
Evaluate top suppliers, randomly select and analyze their raw materials to confirm compliance with national regulations and ensure mechanical characteristics align with product specifications.
2. Once the forgings arrive at the facility, quality control personnel carry out visual checks and precise dimension verification to confirm the absence of visible flaws, ensuring a sufficient tolerance for final product manufacturing.
2. Rough turning
1. Descaling rough turning: according to the size of finished products, reserve enough size margins.
2. Ultrasonic defect inspection: forged parts following rough machining are examined using ultrasonic waves to identify material imperfections, including porosity, inclusions, and layering, among others.
3. Tempering treatment: according to the national standard or the special reguirements of customers, the tempering treatment could improve the mechanical properties.
4. Hardness testing of tempering treatment: Testing whether the overall hardness of forgings is qualified according to quenching and tempering hardness requirements.
3. Precision turning before quenching
A suitable clearance is established based on the raceway's design and dimensions to compensate for both machining and quenching-induced distortions, while minimizing the leftover material as much as feasible.
4. Quenching and temper stability of raceway.
The raceway undergoes medium frequency quenching treatment. The hardened zone attains a hardness of HR(SS-62 and maintains a minimum effective depth of 3 mm. Following quenching, a stable tempering process is applied to relieve internal stresses, minimize deformation during later machining, and lower the likelihood of raceway fractures.
5. Detection of hardness, depth and crack
Detection of hardness. effective depth and crack in quenched area. especially initial position.
6. Quenched semi-finish turning
Processing datum level, providing datum for subsequent processing of teeth, holes, etc.
7. Tooth processing
According to different kinds of tooth shape, processing methods such as shaping, hobbing and milling can be selected.
The accuracy level can meet 7-10 grades. If higher accuracy is needed, grinding can meet 4-6 grades.
8. Hardening, Tempering Stability and Testing of Teeth
To ensure the teeth have sufficient durability and operational lifespan, selective high-frequency quenching is applied to both the root and crown areas based on specific needs. The resulting hardness reaches HRC 40–55, with a penetration depth of 1.5mm. Following quenching, a tempering process stabilizes the structure, removes residual stresses, lowers the chance of cracks forming, and enables subsequent hardness testing and crack inspection.
9. Hole Processing and Detection
Control the chord length, wall thickness. aperture and other items in the machining process and correct them in time
Inspection for threads with high accuracy requirements
10. Fine grinding and testing
Precise grinding is employed in high-accuracy manufacturing to accurately manage ring ellipse, wall thickness, and surface flatness, thereby guaranteeing that final product tolerances align with specified standards or customer specifications.
11. Match clearance
Accurate measurement of part size, Calculating spare parts allowance, according to the requirements of the drawings to match clearance.
12. Assembling
Eliminate ring burrs and ensure surface is free of debris. Fit rollers, cages, seals, and all other components as specified in the assembly blueprint. Hand-rotate the unit to verify smooth operation and the absence of any unusual sounds.
13. Finished product testing
The assembly is completed, detecting whether all aspects meet technical standards.
14. Installation of Sign Mark
Install sign and logo according to customer requirement.
15. Fill grease and Packaging
1. Before product packaging. add corresponding brand and type grease according to customer's requirements to protect raceway from damage.
2. Wooden crates designed for ocean freight are employed to guarantee the secure delivery of goods across varying distances, durations, and geographic locations.
