A superior, low melting, silicone base lubricant which liquefies at body temperature. Because of its composition, you need apply only a very thin film of Stir-Lube® to a stirring shaft to increase bearing and shaft life at least three times over that of a bearing lubricated with glycerine. Non-cooled Ace bearings can be operated at 1500rpm and water-cooled bearings at 2000rpm for many hours with negligible wear.
