Product Name: LYPRS three row roller slewing bearing20081030
Price: ask US$
Detail: slewing ring bearings are built with three independent rows of rollers. Since all loads are transmitted directly to raceway surfaces, which are perpendicular to the load direction, the capacity of each rolling element and each raceway surface is utilized in the most efficient manner. The three-row roller slewing ring bearing offers more capacity per unit size than any other PRS bearing design and is inherently the stiffest style of construction. Frictional torque is lower than other styles under most load conditions. Specifications: RACEWAY DIAMETERS: Standard models are from 12" to 180". Capacities: Contact PRS for load information on special order models. GEARING: Internally geared, externally geared or gearless models are available. APPLICATIONS: Off-shore equipment, Mooring buoys, Stacker/Reclaimers, Dockside cranes, Shipboard cranes, Tunnel-boring machines, Antenna
