Anson Bearing Load Rating Tables

These load rating tables apply when the following installation and operating conditions are met:

  1. Maintain adequate grease lubrication.
  2. Align bearings with shaft for uniform load distribution.
  3. Normal running loads should not exceed ratings shown in load tables. Starting and occasional peak loads should not exceed ratings by more than 100%.
  1. The journal shaft surface should be equal to that of commercial steel shafting (about 32 micro-inches) and the diameter within the tolerances of commercial steel shafting.
  2. Ambient temperature should not exceed 225F for babbitt, 300F for bronze, 250F for ZA and 225F for urethane bushed bearings. If shaft transmits heat from a source such as an oven, the shaft temperature at the bearing should not exceed these ambient temperatures.
  3. Where thrust loads are present, install a bronze washer and fasten it in place with a set screw collar against end of bearing. The bearing ends are finished.
