Pillow Block Units & Flange Bearings (UCP, UCF, UCFL)

Mounted Ball Bearing Units (often termed pillow blocks) combine a precision sealed deep groove ball bearing with a convex spherical outer ring housed within a rigid cast iron or pressed steel mounting block. The spherical matching interface compensates for shaft misalignment, while set-screws (grub screws) or eccentric locking collars firmly secure the bearing inner ring to the commercial shafting.
