SW UCF 204-12 Square Flange Bearing Unit | 3/4 inch (19.05mm) Self-Aligning Cartridge | Heavy Duty Cast Iron
The SW UCF 204-12 is a robust, four-bolt square flange mounted ball bearing unit designed for demanding industrial environments requiring stable mounting and self-aligning capabilities. This unit pairs a high-quality UC 204 insert bearing with a rigid, single-piece cast iron housing (F 204), ensuring maximum durability and resistance to operational stress and vibration. The unit features an extended inner ring for secure shaft mounting, typically utilizing set screws for quick and reliable fixation. Engineered for longevity, the insert is pre-lubricated but includes a grease fitting (nipple) for periodic re-lubrication, extending service life in high-contamination or high-load applications.
Optimized for conveyance systems, agricultural equipment, packaging lines, and textile machinery, the UCF 204-12 provides superior operational efficiency and simplifies maintenance procedures. Its precise bore tolerance (3/4 inch / 19.05mm) minimizes run-out and ensures smooth performance even under moderate misalignment, protecting against premature wear. SW bearings are manufactured to rigorous quality standards, providing reliable performance metrics, including high dynamic and static load capacities, making the UCF 204-12 an essential component for optimizing uptime and reducing total cost of ownership in critical industrial infrastructure.
