Railube Bio Flange Oil SG7
Railube Bio Flange Oil SG7
Railube Bio Flange Oil SG7 is a synthetic ester structured lubricating liquid grease formulated with special additives, graphite and biodegradable special ester base oils for the lubrication of flange.
Usage
Railube Bio Flange Oil SG7 is used as a lubricant to reduce friction and thus wear between rail and wheel flanges.
Features
- Low Wear Costs:
Provides significant reductions in wheel and rail wear, and improved vehicle safety is ensured by high adhesion and low friction. - Easy Application:
Provides an efficient spray system onto wheel flanges. - High Protection Performance:
Extends the lifespan of wheels and rails. It does not lose its performance regardless of climate and operating conditions. It is insoluble in water and cannot be removed from the surface it adheres to by washing with water.
