Double Row Ball Slewing Bearing
This double row ball slewing bearing features two concentric raceways with steel balls of differing diameters arranged in upper and lower tracks, enabling simultaneous support of radial, axial, and overturning moments. The bearing is manufactured from Chrome Steel GCr15 / SAE 52100 with case hardening, providing high surface hardness and core toughness for extended service life under heavy cyclic loads. The raceway angles are designed at 90 degrees to optimize axial force capacity, a standard configuration for industrial slewing applications.
The open design allows for direct ball placement without cages, reducing friction and enabling higher load density compared to caged designs. This construction is typical in bearings used for excavators and wind turbine pitch systems, where contamination resistance and maintenance intervals are critical. Material hardness ranges from HRC 58 to 62 on the raceway surfaces, consistent with DIN 5401 and ISO 663 standards for slewing bearings. Surface finish is ground to Ra ≤ 0.4 μm to minimize wear under boundary lubrication conditions.
These bearings are commonly purchased by OEMs in construction machinery, mining equipment, and renewable energy sectors requiring reliable rotation under combined loads. Buyers typically require delivery in single-piece packaging with rust inhibitor coating and cardboard outer boxes. Trade terms are usually FOB Luoyang or CIF port of destination, with lead times of 4 to 8 weeks depending on order volume. Customization for non-standard bore sizes or sealing options is available upon request.
| Material | Chrome Steel GCr15 / SAE 52100 (case hardened) |
| Raceway Configuration | Two separate raceways with upper and lower ball tracks, 90-degree load angle |
| Ball Diameter Variation | Different diameters in upper and lower rows to optimize load distribution |
| Surface Hardness | HRC 58 - 62 on raceway surfaces (typical for industrial slewing bearings) |
| Surface Finish | Ra ≤ 0.4 μm (ground finish, standard for high-load slewing applications) |
| Typical Application Load | Axial force dominant; radial load should not exceed 1/10 of axial load without special design |
| Standard Compliance | Meets DIN 5401 and ISO 663 for slewing bearing dimensions and tolerances (typical) |
| Sealing Option | Typically supplied without seals; external sealing can be added per request |
| Lubrication Type | Designed for grease lubrication; standard grease type is lithium-based, NLGI 2 (typical) |
| Operating Temperature Range | -20°C to +120°C (standard operational range for case-hardened steel slewing bearings) |

Sourcing Double Row Ball Slewing Bearing from Luoyang Jiawei Bearing Manufacturing Co., Ltd. - China Import Guide
Before placing an order, verify the exact bore and outer diameter tolerances, raceway hardness certification, and load capacity ratings for your specific application. Request a material certificate and dimensional drawing from Luoyang Jiawei. Confirm whether the bearing is supplied with rust inhibitor only or if additional sealing is required for your environment. Do not assume standard dimensions match your existing equipment without cross-referencing the supplier’s technical drawings.
Lead time typically ranges from 4 to 8 weeks, depending on order volume and customization. Incoterms are usually FOB Luoyang or CIF destination port. Payment terms are commonly 30% advance with 70% against shipping documents. Buyers should confirm containerization details, as these bearings are heavy and may require palletized shipping. Request a packing list that includes rust prevention method and handling instructions.
Perform incoming inspection for surface defects, raceway smoothness, and rotation torque. Use a dial indicator to check axial and radial runout. Verify that the material matches the certificate and hardness readings fall within HRC 58 - 62. Retain a sample bearing for reference if installing multiple units. Ensure all documentation, including test reports and export certificates, is provided before customs clearance.
