I do have a couple possible options for you as we do not carry an exact replacement for your National 203025. We have the Bearing Buddy Seals # BB60001 designed for a 1" spindle using Bearing # L44643 or Seals # BB60005 designed for a 1-1/6" spindle using Bearing # L44649. These utilize a stainless steel ring for a polished grease seal surface.
