нашел тему по смазке на форуме Ленко.
"не все просто в датском королевстве"(С) кому интересна тема на английском языке

наиболее доступно и понтно мне показался ответ от фирмы изготовляющей эти самые пдшипники скольжения

Цитата:Standard Oilite® bearings are impregnated with a highly refined mineral oil to ISO VG (SAE 30) having a high viscosity index and containing anti-oxidant, anti-rust and defoamant additives.

To prevent possible seizures with stainless steel, hard-chromium and nickel plated shafts, an addition of molybdenum disulphide to the impregnation oil must be specified.

Any particular application thought to be outside standard conditions should be referred to our Technical Department.

However, here are some basic rules:

Low viscosity oil for low temperatures, high speeds or light loads
High viscosity oil for high temperatures, low speeds or heavy loads
High viscosity index oil for wide variations in operating temperatures
Oxidation stable oils for long-period usage
Oil with 'oiliness' additives for boundary conditions
Oil of lesser 'oiliness' for full film (hydrodynamic) conditions
Oil with Extreme Pressure (E.P.) additives for very heavy or shock loads

Machined Oilite® bearings and plates are supplied fully impregnated after machining. A wide range of lubricants are available to meet specific requirements within a temperature range of -60°C to 200°C, lubricant additives are also available to impart anti-wear properties in marginal lubrication conditions. Special additives are also available for use with various shaft materials and finishes.

It is highly recommended that additives are employed when using stainless steel shafts. Please contact our technical department for advice on specific applications.
