Choosing between a flange bearing unit and a face-mounted shaft collar starts with one question: does the shaft need to rotate, or does it need to be clamped and held in place? The two parts here look similar because both mount to a flat face and both fit the same bore size, but they do very different jobs. The FYH UCFL20516EG5NP is a mounted ball bearing unit for rotating shafts; the Summit Collars face-mounted unit is a shaft collar/hub coupling for clamping and positioning. Price, material, and mounting details decide which one belongs in your cart.
Quick Verdict
If you need true rotating support, choose the FYH UCFL20516EG5NP 2-bolt flange bearing unit. It is the lower-priced option of the two and gives you a complete mounted bearing unit rather than a shaft collar. If you need a clamping collar that mounts to a face, choose the Summit Collars face-mounted shaft collar. It is the higher-priced option, but it is built for a different purpose: clamping around the shaft and providing mounting flexibility rather than acting as a bearing.
Price and Spec Comparison
| Product | Price | Price Bar | Shaft/Bore Diameter | Key Detail |
|---|---|---|---|---|
| FYH UCFL20516EG5NP | $23.99 | 1 in | 2-bolt flange bearing unit; nickel-plated cast iron housing with ball-bearing insert | |
| Summit Collars Face Mounted Collar | $38.65 | 1 in | Face flange mounted shaft collar/hub coupling; aluminum black anodize; three tapped counterbored holes and three unthreaded holes |
Where Each Product Wins
- The FYH flange bearing unit wins for rotating shaft support because it is a complete mounted bearing unit at the lower price.
- The Summit Collars shaft collar wins for clamping and hub-mounting jobs because its mounting-hole layout gives you more flexibility when bolting to a face, hub, or coupling.
Product Notes
FYH UCFL20516EG5NP Nickel Plated Flange Bearing Unit
The FYH UCFL20516EG5NP is a complete mounted bearing unit, not just a shaft collar. It brings together a ball bearing insert, a cast iron housing, and a corrosion-resistant nickel-plated finish in a flange configuration. That combination makes it a natural fit for washdown-oriented machinery such as food processing equipment, conveyors, and packaging systems, where the housing is exposed to moisture and cleaning. It is listed as new open-box, so you are getting a new unit rather than a used part. Choose this one when you need a bearing that supports a rotating shaft and you want the lower price point. The trade-off is that it is specialized as a bearing unit; it will not serve as a clamping collar for a shaft that needs to be held rather than rotated.
Summit Collars Face Mounted Shaft Collar
The Summit Collars face-mounted shaft collar is a different tool for the same shaft size. This version is aluminum black anodize, a lightweight finish that offers good corrosion resistance. The collar clamps evenly around the shaft to create a strong, mar-free hold, and the three tapped counterbored holes plus three unthreaded holes give you options when bolting it to a face, hub, or coupling. It is listed as new and carries the higher price of the two products. Pick it when your task is positioning, clamping, or hub-mounting a shaft rather than supporting rotation. The limitation is that it is not a bearing unit, so it cannot take on the role of the FYH flange bearing in a rotating-shaft application.
Final Choice by Use Case
For rotating shaft support, go with the FYH UCFL20516EG5NP. It is the true bearing option and costs $14.66 less than the Summit Collars' $38.65 price. For face mounting a shaft collar or hub coupling, choose the Summit Collars unit at $38.65; it is built for clamping and face-mounting flexibility rather than rotational support.
