These slewing rings feature exceptionally durable radial cages and are capable of sustained high-speed operation. High-speed operation requires selection based upon dynamic capacity limitations which impose more severe limits on loads than static capacity. Available in gearless models only. 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 Rotek bearing design and is inherently the stiffest style of construction.
Frictional torque is lower than other styles under most load conditions.
Special order up to 14 meters. Internally geared, externally geared or gearless models are available. The Series 15,000 is ideal for applications where it would be difficult or impossible to remove and replace the slewing ring. Raceway inserts and rolling elements are available in stainless steel. Supporting rings are available in a wide variety of materials, including steel, aluminum alloy and bronze.
