BiRAL N-720

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


The extra rust protection also makes the grease suitable for wet and corrosive environments.  BiRAL N-720 is suitable for heavily loaded industrial applications where water wash out is problematic.  The grease is also suitable for heavy-duty vehicles working outdoors in wet and dirty condition.


*BiRAL N-720 is used worldwide in various maritime applications not least in radar navigation equipment, marine stabilisers & hydrovanes.
