RAIL GREASE MS-27 and MS-27z

Product ID: ТУ 2113-004-70470322-2009
Storage conditions: Guaranteed storage life in original containers is 3 years.
Composition: Rail greases are based on mineral oil and contain organic and mineral thickeners, adhesives and an additive package.
Field of application: Rail Greases MS-27 and MS-27z are designed to reduce wear of rails and wheel flanges. Grease is applied to the rail-head side edge with the use of railroad lubrication cars. By order of Russian Railways JSC as of January 20, 2012 No.76р "On the admission of lubricants", Rail Grease MS-27 ТУ 2113-0047040322-2009 produced by the KGP company is admitted to be used at Russian Railways JSC. Rail Grease MS-27z is used in winter at the air temperature from -10°C to -45°C. On the basis of acceptance tests carried out by the Railway Research Institute (JSC "VNIIZhT"), Rail Grease MS-27z has advantages over other lubricants used at negative temperatures:
  • - critical load (Pcr) (921N);
  • - welding load (Pw) (over 4381N);
  • - a better viscosity-temperature characteristic.
The research conducted by Rostov State Transport University has showed that Rail Grease MS-27z does not cause segregation of metals.
