Description

Longlife 1200 is a multi-purpose synthetic grease developed for high speed turbine engine bearings and conforms to Mil-G-81322E. It has excellent long life and anti-rust properties for service temperatures ranging from -80°F to 400°F. It can be operated to 600°F, depending upon speed and load, environmental factors, and relubrication frequency.

Application

Longlife 1200 is highly recommended for use in a wide range of industrial equipment. Use on sheathed cables, O-rings, seals, gears, ball, roller, and plain spherical bearings. It is especially suitable for use in plastic and/or metal gear boxes where service temperature range and minimal evaporative losses are critical.
