Product Announcement from RBC Bearings
RBC's patented TJ design provides the best of both worlds with respect to operating loads and speeds. With two rollers per cage pocket, RBC's TJ design delivers more load carrying capability than competitor's standard, caged, needle roller bearings.
The RBC TJ design significantly reduces the "roller scrubbing" that plagues full complement bearings. "Roller scrubbing" dramatically increases operating temperatures, which in turn causes a premature breakdown of bearing lubrication. Once the lube film breaks down, the rollers and raceways "micro-weld" and trade material, causing rapid bearing failure.
This is important as "skate bar" replacement is time consuming and expensive!
