Speciality Lubricant
Rolgard® is a unique high-performance and high-temperature lithium based grease reinforced with PTFE. Rolgard® deposits a fine, tenacious, clinging film on the applied metal surface and the innumerable micro particles of PTFE act as tiny ball bearings that help minimise friction and temperature buildup.
The presence of PTFE in Rolgard® helps propagate smoother movement between movable and interfacing parts even at high speeds and temperatures.

- The grease is known to be mechanically and chemically stable, providing effective lubrication at temperatures upto 250°C
- Excellent for all metal to metal lubrication
- Chemically and mechanically stable. Does not soften or harden, unlike ordinary greases
- Excellent thermal stability. Resists oil separation and does not migrate from hot surfaces
- Withstands a wide temperature range, –5 to +250°C
- Excellent shear stability. Remains where originally applied for extended periods
- Reduces friction and wear
- Cuts wasteful energy consumption
- Controls heat build-up. Safeguards your precious equipment
- Reduces noise and vibration, especially in large gears
- Contains no chlorine which has been known to promote corrosion
- Contains no silicone which has been known to cause migration problems
- High di-electric strength
- Offers greater malleability than graphite, MoS2 and other solid lubricants
- Joints treated with Rolgard® are easily dismantled, even after years
- Increases life of equipment
- Minimises downtime and maintenance costs
