Ciatim-221

The Ciatim-221 grease (GOST 9433-80) is an organosilicon liquid, thickened by complex soap, it contains an antioxidizing additive.
The basic operational characteristics: it is insoluble in water, hygroscopic, saves stability even at boiling. At moisture absorption it is condensed, has the low antiwear characteristics chemically proof, inert to rubber and polymeric materials. It is efficient at residual pressure 666,5 Pases in the range of temperatures from -60°С to +150°С.
Scope: bearings of a rolling of electromachines, control systems and devices with frequency of rotation to 10000 mines-1, modular bearings of flying machines, friction units and the interfaced surfaces «metal-rubber» working in vacuum.
