Need to support a rotating shaft on a flange, or connect two shafts together? These two power transmission parts solve different problems: the FYH flange bearing unit is a mounted bearing for shaft support, and the uxcell rigid shaft coupling is a steel connector for joining shafts. The right pick depends less on cost and more on what your machine needs.
Quick verdict
If your task is to mount and support a rotating shaft, the FYH flange bearing unit is the functional match, with a corrosion-resistant nickel-plated cast iron housing and a ball bearing insert. If your task is to rigidly connect two shafts, the uxcell rigid shaft coupling delivers a black oxide-coated steel body and four set screws. Choose by function first, then by bore size.

Where each product wins
- FYH wins if your priority is a mounted bearing that supports a rotating shaft.
- uxcell wins if your priority is a rigid coupling that joins two shafts for torque transmission.
Product notes
NEW FYH UCFL20516EG5NP 1" Bore Nickel Plated 2-Bolt Flange Bearing Unit
The FYH unit is built around a 1-inch bore and a ball bearing insert, housed in a 2-bolt flange made of nickel-plated cast iron. That finish makes it a practical fit for damp or washdown environments, and the flange style is designed for mounted bearing support. At $23.99, it is the more affordable of the two products. The trade-off is that the bore is fixed at 1 inch, so you need a matching shaft, and the condition is noted as "New - Open box," meaning the packaging may be opened even though the unit is new. For a straightforward flange-mounted bearing support with a 1-inch shaft, this is the part to consider.
Shaft Coupling 7/8" Bore 1-3/4" OD 2" Length Rigid Coupling, 4 Set Screws
This uxcell coupling is a rigid connector for two 7/8-inch shafts, with a 1-3/4-inch outside diameter and 2-inch length. The 45# steel (ASTM1045) body gets a black oxide coating to help resist corrosion, and the four set screws are designed to hold the shafts firmly in place. It uses a simple set screw mechanism and can be installed without special tools or professional help. The listed price is $34.32, making it the higher-priced option. The coupling also carries a California Prop 65 warning for cancer and reproductive harm, which may be a consideration depending on your state and workplace.
Final choice by use case
Choose the FYH flange bearing unit when you need shaft support. Choose the uxcell rigid shaft coupling when you need to join two shafts. For bearings, couplings, and power transmission tasks, the biggest factor is matching the bore to your shaft, then deciding whether your application needs shaft support or shaft joining.
