Hello all,
I have a SB 9 headstock casting with spindle bearings that are segmented rather than smooth. The large bearing has 14 segments and the small (LH) bearing has 10 segments. It is a front oiler with bottom spring wicks and looks very similar to other 9 headstocks. The bearing cap bolts are not slotted or hex cap screws but are rounded hex head bolts. I think it is a later model due to the SB green paint. My 9" spindles fit nicely into the headstock. I think I saw this described as a "high-speed bearing" model.
Can anyone shed more light on this?
Bob
