GQZ UCP204 Two-Bolt Pillow Block Bearing Unit 20mm Shaft Cast Iron Housing Equipped With UC204 Insert Bearing

The UCP204 is a standard two-bolt pillow block bearing assembly, consisting of UC204 self-aligning insert ball bearing and P204 cast iron housing with double set screw locking structure. It mainly bears radial load and withstands slight axial load. The spherical outer ring provides self-aligning capability to compensate minor shaft misalignment, widely adopted for base mounting of various rotary machinery under dusty and humid working conditions.
