Premium through-hardened wheel bearings from National Wheel End Components are engineered to deliver increased strength and dimensional stability, ensuring longer service life in the most demanding operating environments for heavy-duty trailers. The bearings are manufactured through the same processes and with the same equipment as original equipment bearings to deliver the exact fit, performance and durability, the company says.

Combined with OE-style crowned raceways and rollers, a high-strength steel cage and matched rollers, the new bearings offer both performance and dependability, according to the company. For more information, go to
