Feiken short base pillow (plummer) block ball bearing units adhere to the Japanese Industrial Standards (JIS). These units comprise an insert bearing mounted in a cast iron housing with an extended inner ring and set screw locking. This variant has threaded holes for attachment bolts and is suitable for applications where the direction of rotation is constant or alternating. These enclosures can be securely bolted to machine walls or frames. While accommodating moderate initial misalignment, Feiken ball bearing units typically do not allow axial displacement.
