R-SEAL – RA-RR SERIES ExTENDED INNER RING AND RADIAL BEARINGS

The RA-RR series bearings feature Fafnir’s positive contact, landriding seal developed especially for agricultural applications . The nitrile rubber seal lip is molded to a close clearance heavy metal shroud cap This shroud design prevents injury to the seal lip and provides improved protection from dirt, dust, fibre wrap and abrasion . Seal back-up is provided by a ground shoulder on the inner outside diameter (O .D .), inboard of the seal to eliminate seal lip inversion . The sealing surface is crush-ground simultaneously with the ball race to provide excellent surface finish and concentricity

The RA-RR series features an extended inner ring and self-locking collar for simple effective shaft retention in a standard series bearing. The positive contact, land-riding R-seal (described in detail on page 5) provides improved protection against the heavy contamination normally encountered in agricultural applications. A heat stabilized, moisture conditioned 6/6 nylon retainer has proven extremely effective under conditions of misalignment. Economical RA-RR series bearings are ideally suited for moderately loaded, moderate speed applications.
