Does anyone know the actual Bearing numbers for a J series Head? Looking for the top cap bearing, and the bearing under the adjuster plate for the variable speed.
I don't need the spindle bearings. Thanks

Very friendy, helpful folks too. They know Bridgeports and get parts out ASAP.

In lieu of that, measuring the ID (1.375 IIRC) / OD (2.375iirc) , how thick, thrust, etc and contacting a local bearing supply house can get you fixed up too. Pretty sure they're all spec'd abec-7 / sealed.

They are only regular deep groove Bearings 2RS is all that is needed, the spindle is the only part that has ABEC 7 Bearings
