Description of Suffixes and Prefixes :
TRTB - Tapered Roller Thrust Bearing
VF - V-Flat Configuration
other salient points to be noted :
• RBC manufactures a comprehensive line of heavy-duty V-Flat tapered roller thrust bearings, with bore sizes ranging from 5 inches (127 mm) to 17 inches (431.8 mm). These bearings are specifically engineered for high-performance in extreme environments, making them ideal for tough applications such as oilfield top drives, swivels, extruders, and other heavy industrial uses.
• RBC’s TRTB-VF Series V-Flat tapered roller thrust bearings feature a unique design with one tapered raceway and one flat raceway. They include a pin-type cage and roller assembly with controlled-contour rollers, which optimize stress distribution across the contact surface. This advanced design delivers maximum load capacity within a compact envelope. Bearings in this series are available with either bronze or pin-type cages, both providing enhanced performance for heavily loaded applications.
• TRTB-VF Series V-Flat tapered roller thrust bearings from RBC are also offered in MAX3™ steel, delivering superior fatigue life for applications requiring increased durability and performance.
Advantages of RBC heavy-duty tapered roller thrust bearings :
• Interchangeable with Industry Standard Product Offerings
• High Shock Resistance
• Application Flexibility – Assemblies are available with bore reliefs on larger sizes, optional on smaller sizes – to fit a variety of unique applications.
