Short answer - no

This is a cylindrical roller bearing- R&M MMRJN1M has 1" Bore 2-1/2" OD 3/4" Wide.

For the early Austin 7 you need a front crankshaft roller bearing- R&M MRJ 1 1/8", rear crankshaft roller bearing R&M MRJ 1 1/4"

R&M is now RHP.

Thanks Tony,

I was sure you would be able to help. I didn't recognise it but thought it was worth checking.

It must have been for something else and got mixed up in the A7 spares

Dimensions as RN RP pinion ball. Is it an earlier pinion roller?

Correct dimension but has shoulders on both inner and outer ring so no axial movement possible.

Which, if not standard for some earlier model, makes it a direct and probably originally expensive replacement for the somewhat inadequate RP ball with no need to pin the outer ring.
Some ball pinions I have removed have had nil play when free, suggesting a close tolerance bearing may have been sold for this application.

Interesting possibility !
