Shrus 4M
TU 0254-007-46977243-2004
Lubrication plastic «SHRUS-4M» is an oil oil thickened with lithium soap of 12-hydroxy stearic acid and contains antioxidant, extreme pressure and antiwear additives, including. disulfide molybdenum.
The lubricant «SHRUS-4M» is designed for lubricating the hinges of equal angles of wheel speeds of front-wheel-drive cars such as VAZ 2109, 2108 and similar units of the KRAZ family, as well as bearings of wheel hub, clutch release bearing, propshaft spider, and other high- industrial equipment. In bearings and other friction units, lubricants can be used instead of lubricants: SHRUS-4, No. 158, FIOOL-2U, LZ-31, SHRB-4, AM-cardan, Litol-24.
On performance characteristics, the lubricant «SHRUS-4M» meets the modern requirements for automotive lubricant antifriction. Water resistant, has increased anti-wear characteristics. It is made by thickening of petroleum oil with lithium hydroxystearate, contains antioxidant, antiwear additives and antifriction additives, including molybdenum disulphide.
Grease «SHRUS-4M» is operable from -40ºС to + 120ºС.
