I am about ready to drill and bore the holes for my Y axis thrust bearings. These are the 3 piece - 2 steel "washers" with a nylon disk holding the ball bearings - type of thrust bearing that I've seen on a number of mills here. Mine are 24mm OD, 12mmID and 6.35mm wide.
To what dimension should the hole for the 24mm ring be? Should it be slightly oversized so the outer ring can rotate freely? And how deep should the hole be? I suppose if the bore is slightly oversize, the bore should be deep enough to prevent the outer ring from pressing against the table bed.
thanks in advance,
Michael
