Bearing Modification Services

At times bearings require special or unusual features, but as is often the case they are expensive, have very long lead times or are simply not available at all. GLN has the capacity to modify many types of bearings to customise them to your needs.

Bearing Modification To Your Specific Requirements

Modifications and special features include:


  • Addition of internal or external lubrication grooves and holes
  • Convert parallel to tapered bore (K or K30)
  • Radial internal clearance (R.I.C) increase
  • Alteration of bore/OD diameters or tolerances
