This bearing housing unit accommodates a radial insert ball bearing secured with an eccentric locking collar, mounted in a cast iron housing. The bore diameter is 40.0 mm, overall height is 99.0 mm, net mass is 1.54 kg, and the basic dynamic load rating is 34500.0 N. Sealing is provided by P seals on both sides of the bearing. The eccentric locking collar allows secure fixing of the bearing onto the shaft without requiring additional shaft modifications, while the P seals restrict the ingress of contaminants and retain grease within the housing. The cast iron housing construction gives the unit sufficient rigidity for the stated load rating, and the self-contained design of the unit simplifies alignment and mounting at the specified bore diameter.
