Overview
The FYH UCFB-204-NP is a compact 20mm bore mounted bearing unit combining a deep-groove ball bearing insert with a rugged 3-bolt cast-iron housing. Equipped with a premium C3 precision insert bearing housed within a high-strength solid-base cast-iron housing, this self-aligning flange bearing is engineered for straightforward installation and long-term durability in industrial and commercial applications.
Key Features
- Self-Aligning Design: Consists of an insert bearing with a spherical outer diameter in a 3 bolt cast iron housing. The bearing is often mounted to the shaft by two set screws in the extended portion of the inner ring
- Sealed for Lubrication: Features ball bearings in cast iron housings that allow for self-alignment and have double lip seals for grease retention. Grease fittings are included to facilitate lubrication
- Compact Mounting: Three mounting holes provide excellent stability and control for the mounted bearing in limited space applications
- Industrial-Grade Reliability: Added features improve the overall life and performance of the unit, such as; a steel retainer, wide inner-ring, anti-rotation device, relubricating capabilities, and strategically placed set screws
