I think the bearings on mine were two angular contact bearings, one at each end of the quill but I changed them to a pair of tapered roller bearings, I think I have a pair of new originals kicking about if I come across them when I start unpacking the tools I'll let you know the sizes. These were readily available in both angular contact and tapered roller.
