ISO-Certified Manufacturer with 30+ Years of Expertise in Metallurgy, Port, and Construction Applications
When your heavy machinery demands reliability under extreme stress, roller slewing rings deliver unmatched performance. These robust bearings use cylindrical or tapered rollers—instead of balls—to handle higher loads, resist impacts, and endure harsh environments like steel mills, port cranes, and mining sites. At LUOYANG INNO BEARING CO., LTD, we’ve spent three decades perfecting slewing ring designs that combine precision engineering with industry-specific durability.

✅ Heavy-Load Champions
Built with GCr15 bearing steel rollers and 42CrMo alloy rings, our roller-type slewing bearings support radial/axial loads up to 5,000 kN. Ideal for port cranes lifting 100+ tons or mining excavators operating in abrasive conditions.
✅ Customization in Days, Not Months
Need a non-standard design? Submit your CAD file, and our engineers will provide feasibility feedback within 24 hours. Modular production slashes lead times by 30%—even φ3000mm slewing rings ship in 25 days.
