The UC series bearings refer to standardized, widely-used pillow block ball bearing units with adapter sleeves. At their core is a deep groove ball bearing featuring a spherical outer diameter (SPB) designed to fit into the matching spherical bore of a cast iron housing. Adhering to metric dimensions, this series is specifically engineered for industrial applications demanding high load capacity, straightforward installation, and dependable performance.
