Bearing Ring Suppliers and Manufacturers

Specifications: Raceway diameters: Standard models from 12" to 120" Capacities: Thrust: from 80,000 to 2,700,000 pounds Moment: from 16,000 to 6,700,000 pounds Radial: from 16,000 to 800,000 pounds Gearing: Internally geared, externally geared or gearless models are available. Applications: Excavators, Lift truck rotators, Industrial turntables, Capstans, Turnstiles, Mining equipment and Antennas. DPB Crossed Roller Slewing rings are built with V-groove raceways providing two roller paths in each ring. By alternating adjacent rollers at right angles to one another, one-half of the rollers transmit loads in one direction with the other half transmitting loads in the other direction. The crossed roller bearing design provides a higher theoretical dynamic capacity per unit size, greater stiffness, and a lower spring rate than a single roll ball slewing ring design

We can also make the customized products according to customers requirement or drawing. The materials include NBR (Buna-N), Viton, EPDM, HNBR, Silicone, etc. All the products are ROHS approved, and the FDA & NSF61 approved products are available. Also FREE SAMPLES ARE AVAILABLE. Especially, we are supplying the slewing bearing seal strip for wind energy turbine to many bearing manufactures in China. The products are also exporting to America, India etc, and are well received by our customers. We are looking for long-term business partnerships, and we will provide the best service and competitive quotation. The performance of the products is as below: 1. Longer using life. Not less than 20Year. 2. Excellent weathering & ultraviolet resistance. 3. Highly elongation and strong abrasion resistance. 4. Excellent low temperature resistance. 5. Excellent lubricating greases resistance.
