RBC’s experience in the design and production of bearings for coiltube injectors is second to none. Our DTJ-75121-12 incorporates many improved features overcompeting designs.
TJ Design
RBC’s patented TJ design provides the best of both worlds with respect tooperating loads and speeds. With tworollers per cage pocket, RBC’s TJ designdelivers more load carrying capabilitythan competitor’s standard, caged,needle roller bearings.
The RBC TJ design significantly reduces the “roller scrubbing” that plagues fullcomplement bearings. “Roller scrubbing”dramatically increases operatingtemperatures, which in turn causes apremature breakdown of bearing lubrication.Once the lube film breaks down, the rollersand raceways “micro-weld” and tradematerial, causing rapid bearing failure.
This is important as “skate bar” replacementis time consuming and expensive!
