Part identification help

Not sure which INA part you need?

Send your INA reference, envelope dimensions or a clear photo of the part marking, and we confirm the exact part and complete assembly before quoting.

  • Worn or partial markings: send a photo and tell us which details are still unconfirmed.
  • Cam followers: include roller diameter, stud thread and outer-ring profile.
  • Needle and axial bearings: say whether the design needs an inner ring or thrust washer.
  • Any alternative is listed separately, and no technical change is made without your approval.
