TRTB - Tapered Roller Thrust Bearing
Other salient points to be noted:
• RBC manufactures a wide range of heavy-duty tapered roller thrust bearings, with bore sizes ranging from 1.75 inches (44.45 mm) to 16 inches (406.40 mm).
• These bearings are specifically engineered to perform reliably in demanding, high-load environments, such as oilfield top drives, swivels, extruders, and other rugged industrial applications.
• RBC’s TRTB Series tapered roller thrust bearings come with either bronze cages or pin-type cages, both designed to deliver substantially higher load capacity for heavily loaded applications.
• RBC offers TRTB Series tapered roller thrust bearings in MAX3™ steel, providing enhanced fatigue life for applications where increased durability is essential.
Key Benefits of RBC Heavy-Duty Tapered Roller Thrust Bearings :
• Fully interchangeable with standard industry bearings.
• Excellent resistance to shock loads, ensuring reliable performance in tough conditions.
• Versatile design — available with bore reliefs (standard on larger sizes, optional on smaller sizes) to accommodate a wide range of specialized applications.
