Overview
The FYH UCS13 is a medium-duty flanged ball bearing unit engineered for reliable performance in industrial machinery. This model features a grease-sealed deep-groove ball bearing with a spherical outer ring and a wide inner ring with set screw holes, providing both radial and axial load capacity in a compact, flanged housing format. The UCS13 is a direct replacement for Browning VF4S-235 applications and is commonly used across manufacturing, agriculture, and industrial equipment.
