MICROLUBE GL 261

Special lubricating greases for boundary friction conditions and tribo-corrosion.

MICROLUBE GL 261, GL 262 greases are special lubricating greases on a mineral oil base. They also contain special lithium soap and the MICROLUBE additive package, which ensures a wear-free surface finish. Running-in wear is reduced to a minimum. In addition, the MICROLUBE additive package provides protection in the boundary friction regime, thus preventing tribo-corrosion. MICROLUBE GL 261, GL 262 greases have the capacity to absorb high pressures, and they have good anti-corrosion properties.

MICROLUBE GL 261, GL 262 greases are particularly suitable for low to medium-speed plain and rolling bearings, and for swivel movements and vibrations.

Other applications:

linear guides
serrations, multiple spline shafts
small gears, e.g. adjustment gears

They are generally suitable for machine elements potentially subject to tribo-corrosion.

MICROLUBE GL 261, GL 262 greases can be precisely applied by brush, spatula, grease gun, and through centralized lubrication systems

Optimum lubrication in the boundary friction regime, thus preventing machine downtime due to tribo-corrosion
Tried-and-tested for many years and approved by OEMs
Longer component life due to special additives, especially with oscillations and micro-movements
Trouble-free operation of machines due to good pumpability in central lubrication systems
