TSNII-KZ

Grease «TSNII-KZ» (TU 32 TSТ 896-82) is a mix of petroleum oil, propylene glycol and glycerine. It solidified with lithium soap of stearin acid and acids of castor oil; it contains antioxidizing, anticorrosive and antiwear additives.
Grease «TSNII-KZ» possesses excellent deices properties. It have absorbability. It is efficient at temperature -40 … +40°С.
Scope: protection against an icing of current collectors of electric locomotives and an electrorolling stock.

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.

Buksol

Grease plastic «Buksol» (TU 0254-107-01124328-01) used for application in friction units with bearings of a rolling of locomotives, passenger and freight cars including maintained in the conditions of high-speed movement to 200 km/ch. It is applied at an ambient temperature from-60°S to 60°С. Grease use is supposed at temperature in volume of a friction unit to 120°С.

ZHD

Grease «ZHD» (TU 32 СТ 548-83) used for cutting shaft bearings, fingers of cranks and the bearings equipped with floating plugs.
The basic operational characteristics:
It is water soluble, efficient at temperature to 100 °С.
Structure:
It is petroleum oil solidified oil a soda soap of acids саломасла and fatty tar. It contains to 6 % of water and to 1,2 % of alkali (NaOH).

ZHT-72

Grease «ZHT-72» (TU 38.101345-77) is an organosilicon liquid solidified with calcium soap of stearin and acetic acids. It contains an antioxidizing additive and the additive reducing viscosity at negative temperatures. It is cold-resistant; does not call swelling of rubber consolidations of autobrake devices.
It is efficient at temperature-60 … +120°С. The Scope: brakes of locomotives at a rubber friction on metal. Substitutes: ЖТ-79Л, ЦИАТИМ-221.
