After they made further improvements to the oil impregnation and sintering technologies, they received a patent for their lube-free roller chain, as evidenced by Patent #JP20070237969. [5] In the new design, advancements in powder metal bush technology allowed engineers to design a bush that had a smaller diameter yet was stronger, which ...
Tricresyl phosphate (TCP), used for high-temperature operation, often used as an AW and EP additive in turbine engine lubricants, and also in some crankcase oils and hydraulic fluids; Halocarbons (chlorinated paraffins), for extreme pressure operations; Glycerol mono oleate
Extreme pressure additives are usually used in applications such as gearboxes, while antiwear additives are used with lighter load applications such as hydraulic and automotive engines. Extreme pressure gear oils perform well over a range of temperatures, speeds and gear sizes to help prevent damage to the gears during starting and stopping of ...
The size of the particle and many other interrelated components of a lubricant make it difficult to make blanket statements about whether PTFE is useful or harmful. Although PTFE has been called " the slickest substance known to man ", [ 15 ] [ 16 ] it would hardly do any good if it remains in the oil filter .

Engine lubricants are evaluated against the American Petroleum Institute (API), SJ, SL, SM, SN, SP, CH-4, CI-4, CI-4 PLUS, CJ-4, CK, and FA, as well as International Lubricant Standardization and Approval Committee (ILSAC) GF-3, GF-4, GF-5, GF-6A, GF-6B and Cummins, Mack and John Deere (and other Original Equipment Manufacturers (OEM ...
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
Tests are performed to quantify a lubricant's performance for a specific system. This is often done by determining how much wear is caused to a surface by a given wear-inducing object in a given amount of time. Other factors such as surface size, temperature, and pressure are also specified.
