Applications

Wide inner ring bearing inserts like the Fafnir RA103RRB are designed to mount directly into cast iron or pressed-steel pillow block, flanged, and take-up housings. The wide inner ring extends beyond the outer race on both sides, providing a larger contact surface for the locking collar and better resistance to axial loads and shaft misalignment. These bearings are standard components in agricultural machinery — including combine harvester drives, grain augers, planters, hay balers, and other power transmission shafts exposed to dirt, moisture, and vibration. The double-rubber-contact seals (RRB) keep lubricant in and contaminants out, which is especially important in field and farmyard environments. Fafnir's agricultural line was developed specifically for the demanding duty cycles found in farm equipment and remains a well-recognized choice for replacement and maintenance applications on older and current machinery.
