This bearing housing unit pairs a cast iron housing with a radial insert ball bearing held by an eccentric locking collar. Bore diameter is 20.0 mm, overall height 64.0 mm, net mass 0.63 kg, and the bearing carries a basic dynamic load rating of 13600 N. R seals close off the bearing bore on both sides. The eccentric locking collar clamps the inner ring directly onto the shaft, giving a secure fit without additional fasteners and allowing quick disassembly during service. The R seals provide lip contact against the inner ring, limiting ingress of dust and moisture into the bearing. The cast iron housing offers higher stiffness than a pressed steel design, supporting the stated 13600 N dynamic load rating at the given bore size.
