Constalin

Grease Constalin (GOST 1957-73) is a cylinder oil solidified with soda soaps of fat acids of castor oil.
The basic operational characteristics: water resistance low, at contact to water emulsifyd also is dissolved in it. It is efficient at temperature-20 … +110°С.
Scope: friction units of fans of foundry machines, domain and cement furnaces, rolling bearings on a railway transportation, etc.
Appearance and colour: Homogeneous ointment without lumps from light yellow to dark brown colour
Penetration at 25°С, mm, 10-1: 225-275
The content of water, %, no more: 0.5
Vaporability at 150°С, %, no more: —
Drobfall temperature, °С: Not more low 130

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.

Grease «1-13»

Grease «1-13» (TOR 38.40158142-95) is a mix of petroleum oils of low and average viscosity, thickened oil a soda soap of fat acids of castor oil; contains a little calcic soap of the same fat acids.
The basic operational characteristics: low water resistance, at contact with water it dissolves in it.
It is efficient at temperatures from -20 … +110°С. The application: various bearings of a rolling, rarer – sliding bearings; bearings of electric motors, naves of wheels of out-of-date cars, etc.
