Design: UCP pillow block series has two-bolt mounting with set screw locking. Solid Base Housing: Jeremywell pillow blocks are manufactured without cavities and fillers, their solid base makes the bearings stronger and more durable. A solid base helps eliminate material build-up and is easy to maintain unlike a hollow base housing. 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. 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 has set screws that makes the inner ring of the bearing to be fixed to the shaft, preventing slippage. The bearing is sealed on both sides to keep the lubricant in and contaminants out. It has a solid base with 2 bolt holes for easy mounting, installation and safe replacement. It has a solid base with 2 bolt holes for easy mounting, installation and safe replacement. Steel cage evenly spaces balls for reduced friction, vibration and noise. Deep groove geometry for high speeds and supporting both radial and axial loads
