As lubricant oil castor has a number of advantages in comparison with mineral oils: wide range of working temperatures (t of freezing = - 16 °C, t of flash =275 °C), insolubility in oil products, not toxicity, not aggression in relation to the majority of plastic. The main shortcomings limiting use of this substance as lubricant are its bystry oxidability and low heat conductivity.
At the beginning of development of aircraft castor oil was used as engine oil for piston aviation engines. Now has application in aircraft modeling in the lubrication system of kalilny and compression engines.
It is used for lubricant of details of cars in the food industry and as a component of plastic lubricants (for example, "VNIINP - 291", "Benzinoupornaya").
Liquids for hydraulic actuators
Liquids on a castor basis for hydraulic actuators of brakes of cars were widely widespread in the past. Consisted of mix of equal shares of castor oil and alcohol. ESK liquid — ethyl alcohol and castor oil, BSK — butyl alcohol and castor oil.
The first is not made long ago as has the low temperature of boiling and contains easily separated ethyl alcohol. Was in use till 1950th years.
The second is used in brake systems only with drum brake mechanisms (trucks and cars of old models, for example, of GAZ - 24). It Haraterizutsya by high resistance, it is not hygroscopic, is not aggressive for rubber details, has the greasing and anticorrosive properties.
