SV: Rotor grease



This is the type of grease I am using on all my rotators. I am living far North in Norway and periodically experiency extreme low temperatures during winter time. Temperatures between minus 30 and 40 degs Celcius is not rare. Never had any problems after relubricating my rotors with MOLYCOTE BG20.

Molycote BG20:

    - Consists of synthetic oil, lithium complex thickener
    - For high rotational speeds, DN value 800.000
    - Good oxidation resistance = long relubrication intervals
    - Drop point > +230 degs Celcius
    - Temerature range -45 to +180 degs Celcius.
