You probably already know, but please do not even consider using 'copper grease' as a bearing lubricant. It is not intended for this purpose, but as an anti-seize assembly 'barrier'. It's dynamic lubricating properties are very poor - you would better off with butter and you could lick it off your fingers afterwards!!!!I was doing a bit on the bikes today.
I have a large tub of copper grease dated 1986. It is still 3/4 full.
You’ve got a big garage there for your mini mill………..Kluber grease is fit once for the life of the component. I used it in my industrial research friction welding spindle bearings 100kn loading. Once you have done the bedding in runs, it was superb in use. I used to have to adjust the spindle bearings every couple of months to 50 micron play, cold. After the Kluber grease, ran for a year until the project ended without needing adjustment. 2009 price was £1000 per kg and bearing adjustment process took three days. Similar machine here.View attachment 813057
Dont fall into the "British disease" of conflating value and cost. Focus on the value!Just read this thread with interest and thought 'I might buy me some of this Kluber NB52 grease for my wheel bearings' - a quick Google later = no I won't, not when it seems to be £50+ a tube!
