Selection checks

Many airframe sizes are inch sizes. 15.875 mm is 5/8 in; check whether your drawing is in inches before you compare.
The suffix after the size describes a version of the same envelope. Send the full number, not only the basic size.
State the torque, clearance and lubricant requirements from your drawing or specification in the inquiry.
Interchange is matched by dimensions and function and confirmed on your sample or drawing before we quote.

Interchange and drawing-based supply

Send the full part number, your drawing or a sample, the quantity and any test or documentation requirements. We match by dimensions and function and confirm before quoting.

Frequently asked questions

Why are the dimensions not round millimetres?

Most of these bearings are inch sizes. For example 15.875 mm is 5/8 in and 6.35 mm is 1/4 in.

Can you supply an interchange for my part number?

Send the full part number and your drawing or sample. We match by dimensions and function and confirm before quoting.

Do models with the same size but different suffixes differ?

Yes. The suffix marks a different version of the same envelope. Always send the full number.
