Description
MICROLUBE GL 261 Special lubricating greases 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.
- Temperature range: -30°C to +140°C
- Volume: 5kg bucket
- Also available in: 400g cartridge, 1kg can, 25kg bucket, 180kg barrel
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, 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.
