I used WD-40 by the gallon a week on the open bearings on
two water based ink flexographic printing presses.

True it doesn't last long but I hit the bearings three
times a day, morning, mid-day and after washing down the presses
with pressure sprayed water.

Prior to my doing so the machine shop was replacing bearings
and bent shafts on the presses at least once a week,
after I convinced them to buy it it became a once a two month
event at most.
One gallon WD-40 a week some 7 - 14 dollars in 1985, I forget exactly,
as opposed to:
1 45 dollars per bearing replaced in pairs for 90 dollars.
2 Time spent turning down a shaft on a lathe from standard stock
to replace bent shaft.
3 Production time lost, average of 2 1/2 hours
4 Two persons time from the machine shop for time
to repair the printer also 2 1/2 hours for 5 man hours.
5 printing plates usually destroyed by the eccentric print
cylinder motion.
6 Time and materials to replace and assemble destroyed printing plates.

And still they bitched about me using the stuff :-(

It's certainly not a universal lubricant or water displacement
product for all applications but it does have it's niche
uses.
