The oil 132-21 (TU 6-02897-78) is a mix of a polyethilsiloxane liquid and mineral lubricant oils.
It is intended for greasing of bearings in various devices and friction units of the machines working in the range of temperatures -(65-70) … +70°С.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.


Scope: Apply to greasing of high-speed and sensitive ball-bearings at temperature from-40 °С to +100 °С, and as for decrease and stabilisation of a friction, anticorrosive protection in ball-bearings, tooth gearings, sliding sites and as for the landing and not protected surfaces of details in the precision devices filled with air and nitrogen.


The synthetic oil intended for greasing of mechanisms and preparation of plastic greases, and also for use as a dividing liquid. It is efficient in contact to some excited environments in the range of temperatures 50… +50 °С.
