BiRAL N1-720

The thicker consistency super-adhesive grease that:

Will not melt or drip at high temperatures.

Resists low temperatures and the most aggressive environments.


BiRAL N1-720 is highly recommended for use wherever conventional greases drip away or completely disappears over time as a result of heat, wear or washout.


BiRAL N1-720 proves excellent for lubricating slow running gears which operate under heavy loads and under extreme environments e.g.: shipboard*, drilling rigs, mining, quarrying applications. N1-720 boasts incredibly strong adhesive properties. Its very long fibres make it particularly suited for applications involving rotating shafts, cogs, wheels, bearings, components etc.


*BiRAL N1-720 is used worldwide in various maritime applications not least in radar navigation equipment


Commonly supplied in 400gm cartridges and 5Kg tubs. Also available in 18, 50 and 180Kg drums.

  • Operational performance+
    BiRAL N1-720’s lubricating film maintains contact with all moving parts in gears, bearings etc. The high drop point means that N-720 will not melt or drip at high temperatures – up to +270°C. BiRAL N1-720 not only lubricates – it also protects against corrosion especially from salt-water attack and most corrosive chemicals. A very high adhesion factor means that N-720 is also highly resistant to water washout and steam pressure cleaning.
