UCF 218-56 3-1/2 NORMAL DUTY BALL BEARING 4-BOLT FLANGE SET SCREW LOCKING
The 0" Normal Duty UC 4-Bolt Flange Bearing is Moline Bearing Company part 19411308: a mounted ball bearing unit. It is fitted with a single lip contact seal and a set screw locking insert, in a Class 30 cast iron housing with a standard painted finish.
The insert is a single-row deep groove ball bearing with a spherical ground outside diameter that seats in a matching spherical seat in the housing, so the unit self-aligns at mounting. The inner ring is through-hardened in the raceway and left soft where the set screws seat, so they can be tightened without cracking the ring. These units are manufactured overseas for Moline Bearing Company to the quality standard set by the bearing industry, at a lower price.
It ships assembled, adjusted, sealed and pre-lubricated with lithium complex grease, so it mounts straight from the box with no adjustment or cleaning.
