Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
A grease gun (pneumatic) A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'. The channels behind the grease nipple lead to where the lubrication is needed.
Lincoln patented the first lever grease gun to work with a full stroke operation called the Model 1242. This meant that a hand-held grease gun could generate up to 10,000 lbf/in² (70 MPa) of pressure. Operators of the unit could push grease into blocked or "frozen" fittings and the unit allowed for work in confined areas.
This edit by 75.131.110.5 removed every mention of the inventor of the grease fitting, Oscar Ulysses Zerk, and the word Zerk. This seems like vandalism. I've put back the fact that Zerk invented it, but the vandal did quite a job and I don't feel up to fixing every removal of "Zerk". Vaughan Pratt 04:59, 26 January 2018 (UTC)
The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. [12] The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun , but was cheaper to mass produce and lighter, at the expense of accuracy. [ 12 ]
A zip gun constructed from a toy cap gun. The gun is capable of shooting a .22 caliber round. More advanced improvised guns can use parts from other gun-like products. One example is the cap gun. A cap gun can be disassembled, and a barrel added, turning the toy gun into a real one.
Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware.Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones.
Grease is a solid or semisolid lubricant formed as a dispersion of thickening agents in a liquid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil .
