How to Order Replacement Bearings
A step by step guide to ordering the right replacement bearing.

Ordering the correct replacement bearings is a critical task – but one that is not difficult if you take time to gather the right information.

  • Identify the type of bearing you need to place:
    Locate the identification number on the bearing. This is usually located on the inner ring face, outer ring face, or bearing O.D. Mounted units are identified by a number tag fastened to the unit or by as housing number cast into the housing cap.
    • Ball Bearing – Single Row, Double Row, Angular Contact
    • Roller Bearing – Cylindrical, Spherical, Tapered
    • Thrust Bearing – Ball or Roller
    • Split Pillow Block – Pillow Blocks
    • Super Precision – Angular Contact Ball, Cylindrical Roller, Ball Screw Support
    • Linear Motion – Linear Guide, Ball Screws, Monocarriers
  • Measure if necessary
  • If a bearing identification number is not legible, you will need to determine the following:
    The more information available, the easier it will be to identify the replacement bearing needed.
    • Inner ring bore
    • Out rind outside diameter
    • Inner width and outer width
    • Shape of the bore and/or outside diameter of bearing
    • Record any additional relevant information
  • Record unique features such as lubrication holes, snap ring grooves, machined shoulders, as well as application/equipment data.
  • Look in the appropriate section of the manufacturer’s catalogue.

By following these steps, replacing a bearing can be done quickly and easily.
