pillow block ball bearing outer diameter surface of the sphere can be blended with a corresponding concave

   Pillow block ball bearing is a variant of deep groove ball bearings, it characterized by its outer diameter surface of the sphere, can be blended with a corresponding concave spherical bearing in mind the role played tune.

    Its basic properties and deep groove ball bearings should be similar, but because of this relatively rough bearing most of the machinery used in the installation orientation is not precise enough, the hole axis and the seat of the neutral axis of difference, or long-axis deflection the case of large, etc., and also bearing their accuracy is not high enough, some structure is relatively rough, so compare with  the actual performance of the same performance specifications deep groove ball bearings Yaoda quite a discount. For example: with the top wire of the outer spherical ball bearings used in large stiffness difference through shaft deflections, such bearings with seals on both sides, to close to prevent dirt intrusion, the factory had the right amount of lubricant filling.

   Without cieaning, without injecting lubricant  before installation, the bearings protruding wire screw terminal on the top of the shaft are tightened. Permissible dynamic axial load shall not exceed the rated load of 20%.
