    There is always an id number engraved in one of the bearing rings. Considering the status of the bearing, it has to come apart anyway, so you can then identify it. BTW, sure it is 1,75" (=44.45 mm), not a metric 45 mm?

    It probably is metric.. It was built in Sweden.. I just have never seen a tapered roller bearing used in a stern tube before.. I like the idea, but clearly it did not work in this case for whatever reason..

    The shaft does not look to good to me, so I am looking at replacing the shaft, so I will get all new seals and bearings anyway. Currently liking the dripless but still considering all options..

    This is a complete boat rebuild so I have the option to make major changes if necessary.

    If the stern tube assembly comes from Sweden as well, there is a good chance it is delivered by "Rodahl Marine AB" in the city of Lidkoping. They produce a variety of shafting components like that. Easiest way to contact them is by mail to: info@rodahl.se.
