SKF UCP203 – UCP 213 Pedistial bearing Pillow Block Bearing

Material – Cast iron housing, chrome steel bearing
The UCP pillow block bearing unit is equipped with two specially designed setscrews positioned in the inner ring of the ball bearing to lock onto the shaft.
The pillow block set screws are placed at a 90-degree angle to optimize balance between holding power and inner ring distortion. The UCP205 pillow block bearings are relubricatable and offer a full-width inner ring for added stability
The UCP pillow block bearing also features a positive-contact, three-piece, fiber-imbedded R-seal to protect against harm full contaminants and retain lubricant. The setscrew locking mechanism on the pillow block bearing is easy to install and well suited for reversing applications and normal loads
Applications for the UCP pillow block bearing include: Construction, Conveyors, Food and Beverage, Packaging and General Industrial Equipment.

Pillow block bearings consist of a sealed single-row ball bearing with a spherical outer ring which is mounted in housing. Because of the spherical outer surface of the bearing, shaft misalignment can be compensated for. The bearings are manufactured with a plus tolerance. This results in transition or press fits when using shafts with h-tolerances. The shaft is secured by grub screws on the inner ring.
In normal applications, pillow block bearings are maintenance-free due to the lifetime lubrication. In difficult environmental conditions re-lubrication can be carried out over the grease nipple.
All housing dimensions are nominal dimensions for which the usual casting tolerances must be taken into consideration. Pillow blocks are advanced applied in places with simple equipment and spare parts, such as agricultural machines, convey system or construction machines. One unit of pillow block consists of deep groove ball bearings with spherical outer rings closed in double sides and a housing made by gray cast iron or punches steel. A pillow block bearing (Plummer block) is a mounted bearing used to provide support for a rotating shaft with the mounting surface on a parallel line with the axis of the shaft.

Pillow block bearings are generally self-lubricating.
Pillow block bearings are a form of mounted bearing used to provide load support for a rotating shaft axis. The bearing housing mounts to a surface parallel to the shaft axis. Selection of the appropriate bearings can be accomplished based on the shaft size and the radial and thrust load requirements. Pillow block bearings are designed to support a shaft: the mounting surface is on a parallel line with the axis of the shaft. Elongated bolt holes in the base or feet of the unit allow for some adjustment and easy mounting of the pillow block bearing.
