T25 drive side crankshaft bearing

Post by Langster »

So the marks on the roller bearing I pulled out of the casing were SKF 3NU05. Two flanges on outer ring with pressed steel cage.
It appears to be an SKF number that has been retired. The new SKF number would be something like NU305J (J for steel cage).

Going through various posts I have seen mention of "E" or "EC" suffixes for optimized roller configuration (higher load rating) likewise "M" for machined brass vs steel cage.

Any comments on the standard roller configuration with pressed steel cage versus optimized rollers with machined brass cages eg. NU 305 ECML.

Thanks

Ian
