Large Tapered Roller Thrust Bearing
Thrust Bearings
RBC domestically produces and stocks a line of heavy duty tapered roller thrust bearings with inside diameter sizes ranging from 1.75 inches (44.45 mm) to 16 inches (406.40 mm). These highly engineered bearings are designed for demanding applications operating in harsh environments, such as oilfield top drives, oilfield swivels, extruders, pulp and paper mill equipment, and boring mill tables. The RBC TRTB bearings are manufactured from high quality, high cleanliness, carburizing grade bearing steels for excellent service life and are also available in RBC’s proprietary MAX3™ steel for optimized, extended service life requirements (see page 60 for more MAX3™ detail). Standard designs incorporate a robust machined brass cage, however, most of these bearings can be supplied with a pin-type cage for applications requiring increased load capacity.
