UCFC 213-40 2-1/2 NORMAL DUTY BALL BEARING PILOTED FLANGE SET SCREW LOCKING
The 2 1⁄2" Normal Duty UC Piloted Flange Bearing is Moline Bearing Company part 19431208: a mounted ball bearing unit. It is fitted with a single lip contact seal and a single collar, set screw locking insert, in a solid 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.

This configuration
- Fixed. The shaft is located axially at this position and cannot move lengthwise.
- Single Lip Contact Seal. One flexible lip in contact with the insert. Lowest friction of the contact seals, suited to cleaner environments.
- Single Collar. One locking collar secures the insert to the shaft. Standard for unidirectional rotation and steady loads.
- Set Screw Locking. Set screws in the collar bite into the shaft. Simple and widely used; best where rotation is in one direction.
Replacement parts
The bearing insert is UC 213-40, and the housing on its own is Moline Bearing Company part FC213.
Applications
Normal Duty ball bearing units go into lighter-load, higher-speed drives: conveying, screening, material handling, and food and beverage equipment. It is dimensionally interchangeable with industry-standard UC-series units of the same size.
