High quality Pillow Block Bearing GRAE35-NPP-B GRAE40-NPP-B GRAE30 Outer Spherical Bearing
Product Description
The UC bearing is actually a variation of the deep groove ball bearing. The characteristic is that the outer diameter surface of its outer ring is a sphere, which can be fitted into the corresponding concave sphere of the bearing seat to play the role of centering.The outer spherical bearing is mainly used to bear the combined radial and axial load with the radial load as the main one, so it is generally not suitable to bear the axial load alone.The bearings can be mounted with inner ring (with full set of rollers and retainers) and outer ring respectively.This type of bearing does not allow the shaft to be tilted relative to the housing and will generate additional axial forces under radial load.The size of the axial clearance of the bearing has a great impact on the normal operation of the bearing. When the axial clearance is too small, the temperature rise will be higher.When the axial clearance is large, the bearing is easy to be damaged.Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, it can be preloaded to increase the rigidity of the bearing.

Materials
The performance and reliability of rolling bearings are greatly affected by the materials which the bearing components are made from.BXY bearing rings and balls are made of high quality of GCr15 vacuum-degassed bearing steel.Chemical composition of GCr15 bearing steel is basically equivalent to some representative bearing steel as the chart shown below.

Application
Although UC bearings basic performance with deep groove ball bearings should be similar, but because of the bearing are mostly applied in mechanical rough, installation location is not accurate, the axis of the shaft with a hole to neutral, or under the condition of large axial length and deflection etc, and the bearing itself precision is not high, some structure is rough, so the performance of the actual performance comparison on the same specifications of the deep groove ball bearings to play quite a discount.Therefore, the outer spherical bearing is generally used for equipment and parts are relatively simple and not high requirements, such as agricultural machinery, transport systems or construction machinery.
