About Product
The IKO RNAST Series consists of Separable Roller Followers designed as heavy-duty track rollers with high-performance characteristics. These bearings incorporate needle rollers within a thick-walled outer ring, specifically engineered for the rotation of the outer ring. The RNAST type is a separable structure that combines the outer ring, a needle roller cage, and the needle rollers, but is supplied without an inner ring.
