Greasing liquids

Impellent oils represent specially developed structures for greasing of internal components of the engine. Usually contain wide any spectrum of the additives serving for prevention of foaming and corrosion. Impellent oils are issued various degree of viscosity - from 5 to 80. Necessity of application of oil of this or that grade is usually defined by environmental conditions and requirements of the concrete engine. Liquid (easy) oils are usually applied in the conditions of a frigid climate and at insignificant loadings on the engine. Heavy (viscous) oils are used in hot conditions and at strong loadings on the engine. All-weather oils possess characteristics both easy, and heavy oils and usually have designations from 5W-20 to 20W-50.

Transmissionnoe oil is developed for application in differentials, РТ, and other knots where stability to influence of heats is required.

Greasing for components of the chassis and bearings of wheels represents the dense greasing applied in knots, subject to the raised loadings and a friction, such as bearings of wheels, spherical support of a suspension bracket, tips of steering draughts and карданные hinges.

High-temperature greasing for bearings of wheels is capable to resist to influence of the heats arising in bearings of wheels of cars, equipped with disk brake mechanisms. Usually contains дисульфид the molybdenum, being greasing substance of dry type.

White greasing (циатим) represents the dense greasing put on contacting metal surfaces in places where there are problems with the raised humidifying. Remains soft both at low, and at heats, it is not washed away and it is not diluted by water.

Assembly greasing represents special greasing, for application in the conditions of high pressures, usually contains molybdenum and is used for greasing of the knots subject to high loadings (such as radical and шатунные bearings and working ledges of cams) before the first start of the engine after major repairs end.

Silicone greasings are applied to protection of rubber, plastic, vinyl and nylon components.

Graphite greasings serve applications there where oil cannot be used in a kind of problems with pollution (for example in locks). Dry graphite perfectly greases metal details, preventing influence on them of pollution, a moisture and acids. Greasing is electrowire and does not break contact in such knots, as for example the ignition lock.

Молибденсодержащие getting structures are applied to simplification отдавания "the become attached" fixture, and also for greasing of fixture in order to avoid its corrosion in the future.

Teploprovodnaja greasing is not electrowire and serves for installation of electronic modules of ignition from which intensive heat removal is required.
