(Kulpsville, PA) offers self-aligning ball bearings that allow for angular misalignment of the shaft relative to the housing without affecting operation. The ball bearings gain their self-aligning capability from a design incorporating two rows of balls with a common sphere raceway in the outer ring. They are available with cylindrical or tapered bores, in bore diameters ranging from 5 mm to 130 mm.
Basic bearing types include open designs and sealed versions featuring contact seals on both sides. The steel-reinforced rubber seals protect against contaminants during handling and operation. Sealed bearings are supplied as standard, with a lithium base grease suitable for operating temperatures from -22 to 230°F. Users have a choice of cage materials and bearings designed with inner rings, and bore tolerances for easy mounting and dismounting.
