Grewirifc UCP205-16 Pillow Block Bearings (2 Pack) - 1 Inch Bore, 2 Bolt Flange Mounted, Solid Cast Iron Base, Self-Alignment

The UCP pillow block mounted bearing series has two bolt holes, and a set screw lock is designed for mounting onto bearing surfaces parallel to the shaft axis, such as conveyor belts. This ready-to-mount unit has solid base cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds. UCP205-16 Pillow Block Bearing Specifications Whereas, a hollow base is susceptible to build-up that can trap moisture and therefor cause corrosion to the cast iron housing. Jeremywell pillow block bearing's only come with a solid base, making them a lot stronger and easier to maintain than a hollow base. Please don't worry. This is our self-alignment feature. These bearing are meant to have some play in them. When you mount them, just use the shaft to rotate the bearing into proper position, or if it is not out of alignment by much, the bearing will correct their own alignment once they begin to rotate. Because if the bearings were not aligned properly and spinning at high RPMs then sure disaster would happen. So our self-alignment feature is a way to prevent this from happening. 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. 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.
