The NSK UC205 Bearing Pillow Block Unit is a reliable mounted bearing assembly designed to support rotating shafts in industrial and mechanical systems. It features a precision UC205 insert ball bearing with a spherical outer surface and a set-screw locking design, ideal for applications where easy installation, smooth rotation, and maintenance accessibility are required.
Product Overview
The UC205 is part of NSK's UC series insert mounted bearings, which combine a spherical outer ball bearing insert with a pillow block housing (when sold as UCP205). These units allow easy mounting, shaft alignment, and secure shaft locking via set screws.
Core Components
-
Insert Bearing: UC205 radial ball bearing with 25 mm bore, spherical OD, and set-screw shaft locking.
-
Housing (optional): When packaged as a pillow block unit (e.g., UCP205D1), it includes a cast iron housing for secure mounting.
