In the bearing assembly, using an oil bath heating method, in the disassembly of the bearing, use hot oil poured over the heating method.
When oil bath heated SKF bearings, application thermometer control oil temperature to prevent overheating and, at the same time should be bearing placed the separated net or bracket of 50-70 mm from the bottom of Never direct contact with the bottom, to prevent bearing local temperature rise too high, and by oil, dirt impact.
Bearing anti-wear and extreme pressure additives can generally be divided into the oily and wear extreme pressure agent two categories:
The oily additive: FAG bearings oily additive is through physical adsorption film is formed on the metal surface, to improve the friction of the surface of the metal contact function, and enhance the lubricating effect. Top oily additives are: animal and vegetable oils, higher fatty acids, esters, alcohols and other metal soaps, etc..
The antiwear extreme pressure agent: the majority of the NSK bearings antiwear extreme pressure agent is a strong chemical activity of organic compounds, such compounds at room temperature when not afford lubricating effect, while the metal surface under heat and pressure can be is inherently relatively dense chemical film, this film is generally lower than the melting point of the raw metal material, the shear strength is small, when the metal surface friction, wear, and prevents scratches role.
