The Hitachi bearing is a captive ball against thrust pad design and should be oiled the whole way down. As should the Technics, but the bottom of the SL-1200/etc. bearing housing is essentially a sieve. IOWs, the main bearings of a lot of DD decks are almost an afterthought.
The lack of any form of oil reservoir is why Technics specify such regular oiling, although their 'techniques' ignore the fact that there exists a spindle end down the bottom there. IOW, it is an oiled sleeve bearing that just happens to sit upon a thrust pad.
Keep in mind that putting a tiny drop of oil round the upper lip of the bearing well, Technics service style (post cleaning any ring of dirt away), isn't necessarily going to lube the whole works. I suggest you repeat working in a drop at a time, lifting/lowering and rotating the spindle each time to help each drop be drawn in, until such time as none will be accepted.
