4 meters/157 inch slewing bearing ring
The 4-metre (157-inch) slewing bearing ring is engineered for heavy-duty machinery requiring high load-bearing capacity, such as cranes, excavators, and wind turbines. Its large outer diameter provides stability and even load distribution, critical for applications where axial and radial forces are substantial. The bearing is manufactured from high-grade steel, a standard material for slewing rings due to its fatigue resistance and durability under cyclic stress.
Precision machining ensures smooth operation even under extreme loads, with typical industry tolerances for slewing bearings in this size range falling within ISO 286-2 standards for dimensional accuracy. The ring’s design allows for integration into various equipment configurations, including single-row ball, double-row ball, or roller slewing bearings, depending on the application’s torque and load requirements.
This component is widely used in construction, mining, and marine industries where reliability and longevity reduce maintenance costs and downtime. Buyers should confirm the bearing’s raceway hardness, typically 55-62 HRC for high-grade steel slewing rings, and the gearing specifications if the ring includes teeth. The supplier’s location in Luoyang, a hub for bearing manufacturing in China, suggests access to advanced production facilities.
| Outer Diameter | 4 m (157 in) |
| Material | High-grade steel |
| Typical Hardness | 55-62 HRC (standard for slewing bearings) |
| Load Type | Axial and radial |
| Typical Industry Standard | ISO 286-2 (dimensional tolerance) |
| Common Applications | Cranes, excavators, wind turbines, marine equipment |
| Raceway Type | Single-row, double-row, or roller (application-dependent) |
| Typical Gear Module | 6-12 (standard for large slewing rings with teeth) |
| Fatigue Resistance | High (typical for quenched and tempered steel) |
| Operating Temperature Range | -30°C to +70°C (standard for uncoated steel bearings) |
| Lubrication Requirement | Grease or oil (confirm with supplier for specific grade) |
Luoyang Kaixuan Bearing Manufacturing Co., Ltd. is based in the Technology Industry Park, Jianxi District, Luoyang, China, a region known for its concentration of bearing and machinery manufacturers. The supplier operates within an industrial zone designed to support high-precision engineering, indicating capabilities for large-scale production of components like slewing bearings.
The company’s profile does not specify certifications, production capacity, or client histories, but its focus on slewing bearings suggests specialisation in this niche. Buyers should request evidence of quality control processes, such as hardness testing reports or non-destructive testing (NDT) certificates, to verify the material and manufacturing standards. The imported trust tier signals a verified exporter, though response metrics are not provided.

Sourcing 4 meters/157 inch slewing bearing ring from Luoyang Kaixuan Bearing Manufacturing Co., Ltd. - China Import Guide
Before placing an order, verify the bearing’s load ratings and raceway configuration to ensure compatibility with your machinery’s torque and weight demands. Confirm the outer diameter’s exact tolerance, as even minor deviations can affect fitment in large assemblies. Request the material certificate and hardness test results to validate the steel grade and heat treatment process.
Clarify the Incoterms offered by Luoyang Kaixuan; FOB Luoyang is typical for Chinese bearing exports, but CIF or DDP may be available for added convenience. Lead times for custom slewing bearings can exceed 8-12 weeks, so plan accordingly. Packaging for large rings usually includes wooden crates with anti-corrosion treatments; confirm the supplier’s packaging meets your shipping and storage requirements.
Quality checks should include a dimensional inspection using a coordinate measuring machine (CMM) to verify the outer diameter and flatness. Request a third-party inspection report if available, or arrange for pre-shipment inspection by a trusted agency. Documentation such as the commercial invoice, packing list, and certificate of origin are essential for customs; ensure these are provided in English and comply with your country’s import regulations.
