24-722 Timing side crankshaft bearing, where to find a good one?

Hi I'm looking for a new timing side crankshaft bearing to suit my B33, it's the part number BSA 24-722 and it's a large cylindrical roller bearing with a brass cage and a lip on one side of the outer race. The outer race is pressed into the timing side crankcase half, and the inner roller assembly lives on the timing side shaft of the crankshaft. My local SKF dealer doesn't have anything and I'm wondering where people source these from nowadays? Draganfly have them but don't list the bearing manufacturer, I've heard there are some replacements available but of dubious quality (Chinese I believe), can anyone comment on this?

This chart references old bearing numbers.

Hi Nick,

Drop me an email if you struggle, I run my own bearing company in Rossendale, so should be able to help out.
