MICROLUBE GL 261 Special lubricating grease for boundary friction conditions and tribo-corrosion
- MICROLUBE GL 261 grease is a special lubricating grease on a mineral oil base. It also contains 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 grease has the capacity to absorb high pressures, and it has good anti-corrosion properties.
Benefits for your application
- 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
Applications
- MICROLUBE GL 261 grease is 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
It is generally suitable for machine elements potentially subject to tribo-corrosion.
Application notes
- MICROLUBE GL 261 grease can be precisely applied by brush, spatula, grease gun, and through centralized lubrication systems.
