MICROLUBE GL 261
Special lubricating greases for boundary friction conditions and tribo-corrosion
Application MICROLUBE GL 261
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.
Performance, Features & Benefits of MICROLUBE GL 261 are:
- 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

Product Description MICROLUBE GL 261
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.
