The zinc plated finish provides durability under any condition, while the semi-steel wheels are abrasion resistant and rugged, maintaining effortless rolling under heavier loads, and provides a cost-effective solution over steel wheels. The roller bearing is capable of carrying greater loads while also providing smoother rolling motion. It has a split outer race shell into which the roller assembly is inserted.
Combination seal/thrust retainer washers protect the bearing from dirt, water, and chemicals. They also help absorb thrust friction (Note: roller bearing must be used with hardened spanner bushing or hardened shaft). Mounting options include top plate, bolt hole and standard and metric threaded stem sizes.
