Bluesil Grease 33 
Bluesil GRS 33 consists of a silicone fluid thickened with a lithium soap. It is especially designed for use in lubrication of ball-bearings and bearings operating at high or low temperatures (from - 70°C up to + 180°C).Features of Grease 33:

Resistance to heat
Very good stability especially in contact with water and most corrosive media
Negligible effect under vacuum, no change in consistency
Applications:

Greasing of ball bearings or moving parts operating under severe weather conditions or working at extreme high or low temperatures: ski lift-carrier shafts, freezing equipment, electric motors, windscreen wipers, motor gears, rotating beacons for airport run ways, valves in the petroleum industry
Greasing of precision equipment in which the grease consistency must be nearly constant: aircraft switches, geo physical instruments, cameras, photographic equipment
Lubrication of ball-bearings which must operate at the same speed under very low tovery high temperatures: clockwork mechanisms, x-ray equipment, synchronise motors
