RNA Series Needle Roller

Single-row needle roller bearing, with flanges, without inner ring.

Single-row needle roller bearings without an inner ring ( are available here ) consist of a hardened and ground outer ring, with a needle roller and cage assembly. They are an excellent choice for compact bearing arrangements in applications where hardened and ground raceways can be provided on the shaft. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.
