UCP20210 Pillow Block Bearing 5/8 Bore 2 Bolt Solid Base (2 Pieces)Brand New Bore Size: 5/8 InchStatic (axial) Load Rating: 6.65 kN/1500 lbsDynamic (radial) Load Rating: 12.8 kN/2900 lbsMaterial: Cast IronMax RPM: 4000Quantity Per Order: 2 PiecesSelf Alignment Feature: If the bearing is crooked please dont worry. This is our selfalignment 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 its own alignment once it begins to rotate. If the bearings were not aligned properly and spinning at high RPMs then sure disaster would happen. Our selfalignment feature is a way to prevent this from happening.Style: 2 BoltsProduct Description: 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 readytomount unit has solid base cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds. This onepiece pillow block housing allows for a stationary outer ring and rotating inner ring. Insert bearing maintains the separation between moving parts to reduce rotational friction, and to support radial and axial loads. The bearing is secured to the shaft with set screws to prevent slippage. This mounted bearing is used in food and beverage manufacturing, textile industry and many other industrial manufacturing.
