Gear Oils

Product Description

Mobiltac 375 NC, 325 NC ａnd 275 NC extra high performance non-leaded, diluent-type, heavy-bodied open gear lubricants designed for a wide variety of open gear ａnd mining applications. They contain a non-chlorinated, volatile solvent that ensures fluidity during application, even at low temperatures. Once applied, the diluent evaporates ａnd the lubricants take on a flexible, adhesive, high-strength consistency that is maintained throughout their service life. Mobiltac 375 NC, 325 NC ａnd 275NC adhere strongly to gear teeth ａnd other machine elements to resist excessive throw-off, thereby providing a wear-resistant, viscous, continuous film that lubricates well under boundary conditions. Mobiltac 275 NC also contains solid phase EP/anti-wear additive for added equipment protection

Mobiltac 375 NC, 325 NC ａnd Mobiltac 275NC will not harden, chip, or flake in cold weather, are self-healing, ａnd do not form a hard-packed buildup in gear-tooth roots. Dripping ａnd throw-off are minimal, ａnd the lubricants are easily cleaned up with a solvent-soaked rag. The lubricants provide resistance to rain, snow, ａnd process water washing. Their flash points minimise the risk of fire. These new generation gear ａnd mining lubricants are applied easily by hand or by automatic dispensers. Mobiltac NC technology has rapidly become a firm favourite among many open gear users ａnd mine operators around the world
