FETT 4600

FETT 4600

NLGI 2-3

GREASE 4600 (FETT 4600) is a quickly biodegradable lubricating grease based on a special calcium soap. GREASE 4600 (FETT 4600) is primarily used as a sealing grease for main bearing seals in the front area of tunnel boring machines. Due to its consistency (NLGI 2/3) and the high base oil viscosity, the grease offers a very good sealing effect.

What does tribology mean?

Tribology covers scientific research and technical applications of friction, wear and lubrication, taking account of design, materials science, regulations imposed by the authorities, etc. Tribo technology also deals with the retention of the value of machines and tools, simplification of lubrication application, minimisation of energy losses plus environmental demands, cost-optimised production and targeted maintenance schedules.
