The NKE RNA4924 is a precision-engineered needle roller bearing designed without an inner ring, making it an ideal choice for applications where the shaft can be hardened and ground to serve as the raceway. This configuration facilitates a highly compact bearing arrangement while providing exceptional radial load carrying capacity. With a bore diameter of 120 mm, an outer diameter of 150 mm, and a width of 40 mm, this NKE bearing is suitable for demanding industrial environments requiring robust and space-efficient solutions.
