We are getting a little of track here, for the VC-160 I think your looking for tab bearings, now I'm not sure if these are in production, however new victa bearings of the same size, but without the two locking tabs will fit in comfortably mate.
UPDATE:
I stand corected, here's an ebay listing for tab type bearings, check your bearings to make sure there a match before you go in, if there not, theres also the non tab case ones, but again, check your dimensions just to be on the safe side.
