The UCFC 200 series bearing is a specialized mechanical component designed to enhance performance in industrial applications. Combining the functionalities of a pillow block and a flange cartridge bearing, this unit offers a robust solution for heavy-duty environments. This article provides an in-depth analysis of its features, advantages, technical specifications, and real-world applications.
The UCFC 200 series bearing is a unitized pillow block flange cartridge bearing, integrating a spherical outer ring with a built-in flange, a cylindrical inner ring, and a set of balls held by a cage. This design allows for seamless integration into machinery, providing both structural support and alignment flexibility.

The inner ring is mounted on the shaft, while the outer ring is secured within a housing. The flange on the outer ring enables direct bolting to machinery or structures, simplifying installation and maintenance. This configuration ensures easy accessibility for repairs or replacements without disassembling the entire system.
One of the standout features of the UCFC 200 series is its ability to withstand heavy and shock loads. The load distribution across the balls, inner, and outer rings minimizes stress points, reducing the risk of mechanical failure. This makes it ideal for applications involving high-speed rotation or intense operational demands.
The spherical outer ring allows for self-alignment, compensating for minor misalignments between the shaft and housing. This feature reduces friction and wear, extending the bearing's lifespan and improving machine efficiency. According to the National Institute of Standards and Technology (NIST), "self-aligning bearings are critical in applications where precise alignment is challenging" (NIST).
Sealed on both sides, the UCFC 200 series effectively shields against dust, dirt, and moisture. This protection ensures consistent performance in harsh environments, making it a preferred choice for industries like agriculture and construction.
The UCFC 200 series is engineered to meet rigorous industrial standards. Below is a detailed specification table:
| Parameter | Details |
|---|---|
| Outer Ring | Spherical with built-in flange |
| Inner Ring | Cylindrical bore |
| Ball Configuration | Cage-held balls for even load distribution |
| Sealing | Double-sided sealing against contaminants |
| Material | High-strength steel for durability |
