I glad you made that point - I often wondered why roller & ball bearings need lubricating.
On my Progress drill someone fitted a grease nipple into a blind hole.

most tractor gearboxes are filled with engine oil, as are a lot of heavy plant gearboxes. RTFM to a point but once ou understand why what speced you can get cocky change things and see if you got it right. i fill the gearbox on my mk2 golf up with ATF, noticably less transmition loss from doing so, and it's not gone bang yet.
as for landrover swivels, in theory there is an oil bath inside but i don't think that theory survived much past the forcout before the oil got out. for long time people have just poured liquid grease in them, it's not as good a lubricant from what i'm told but the fact that it stays there makes it much better, as ep 80/90 just runs out and lubricates the drive

Not a lot if it's done right for the application. One of my machines uses Nylon bushes wick fed with oil.

Don't know it by name. I think they tried Teflon coated housings instead of chromed.

Yes, use it on the brake and clutch lever pivots on the Kwacker, good stuff for where it is intended but I would not use it in a bearing unless specified to do so.

I have read that overgreasing "frictionless" ( ball or needle) bearings will cause the balls or needles to skid round rather than rotate and in so doing destroy the tracks.
There are some bush applications that are designed to be oiled and not greased as grease dries out in the passage ways , reduces lubrication and leads to seizure - Triumph Herald king pins and Ransomes Marquis rear rollers!!

I've read that the moon landings didn't happen and I don't believe that either. If grease dries out it's the wrong kind of grease. It's a long time since I worked on a Herald but the ones I saw had a grease nipple on the trunnion and any lubrication was preferable to none which was what they usually got.
Heralds etc you are suposed to lube with EP90 (?) using a suitable grease gun - the grease simply dries out in the grooves of the bronze trunnion after doing a tiny bit of work. A legacy perhaps of old design when people knew to grease things little and often to push out contaminated grease? I use a heavy duty shock proof oil in my trials car that uses Triumph uprights - seems to work.
Grease will "dry" out if left pressurised - the "oily" bit simply gets squeezed out and leaves the cake behind - which doesn't do much other than block things up - ever left your grease under under pressure and wondered why the shelf where you left it is oily? . . . You can get greases specifically for pressurised use, but even they give up. The world of grease is way more complicated than I used to think - and way more expensive! Couple of grand for a tub of grease anyone? Which some twonk will leave with lid off in the shop after using a it. . . grrr . . .
I can sort of see why someone might come up with the idea of bearings dragging dirt in - taper rollers tend to pump lubricant from one side to another - get a twin taper roller with a centre feed of lubricant, and you have to consider some way of allowing the lubricant to be pumped though and out the sides, returning to sump, under the motion of the rollers. Something you want to make sure you have covered when designing using bearings that cost a couple of grand! To cope with that, looking at pumping over a litre a minute of oil into a bearing rotating around 150rpm.

is that why all machine men used to get a greasing allowance in there wages might have been an hour a day Badger can you confirm this

Hi, I do. It was used in the steering boxes of RT's and RM's and other AEC vehicles at the bus company.

Used to be used in the gear box's of the Naval 4.5 Mk 5 (HMS Eskimo).
A nice job even to that goby tiff.
