🟢 1. Product Overview The UKP213 is a pillow block (plummer) bearing unit composed of a UK213 insert bearing mounted in a P213 cast iron housing , locked onto the shaft by an adapter sleeve H2313 . Unlike the set-screw type UCP213, the UKP type locks via taper-bore + adapter sleeve, which delivers stronger holding force and easy axial positioning — widely used in conveyors, agricultural machinery and industrial drives.
