Design: UCF flanged series has four-bolt mounting with set screw locking. Self-Aligning Feature: These bearings use wide inner ring ball bearings with self-aligning spherical outside diameters that compensate for shaft misalignment. Pre-lubricated: Bearings come pre-lubricated and ready for immediate installation. A grease fitting is supplied for re-lubrication. Applications: UCF pillow blocks are suitable for a variety of applications such as agricultural equipment, conveyor systems, industrial machinery, food processing and much more. Material: Made to last, our mounted bearings consist of chrome steel (AISI 52100) ball bearings for higher resistance and durability. This series ball bearing unit is a double sealed bearing with a steel cage, set screws and is pre-housed. The double sealed bearing keeps the lubricant in and contaminants out. The steel cage that evenly spaces the balls for reduced friction, vibration and noise. The set screws enable the inner ring of the bearing to be fixed to the shaft, preventing slippage. This bearing has a solid base with two bolt holes which is easy to install and safe to replace. A mounted unit is essentially a ball bearing with a spherical outer ring (self-alignment to avoid any misalignment), the ability to lock on to the shaft, and is pre-housed. Example of possible applications include: mining, metallurgy, agriculture, chemical engineering and conveying machinery, etc. The bearing is sealed on both sides to keep the lubricant in and contaminants out. It has a solid base with 4 bolt holes for easy mounting, installation and safe replacement. Steel cage evenly spaces balls for reduced friction, vibration and noise.
