Double row angular contact ball bearings to improve its abrasion resistance heating

Oil bath heating method can be used in the bearing assembly, disassembly double row angular contact ball bearings, you can use the hot oil poured over heating.
Oil bath heated double row angular contact ball bearings, the application of the 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, do not directly in contact with the bottom, to prevent double row angular contact ball bearing local temperature rise is too high and affected by the oil dirt.
Double row angular contact ball bearing anti-wear and extreme pressure additives can generally be divided into two categories of oily and anti-wear extreme pressure agents:
Oily additives: double row angular contact ball bearings oily additive by physical adsorption film is formed on the metal surface, to improve the frictional function of the surface of the metal contact and to enhance the lubricating effect. Top oily additives are: animal and vegetable oils, higher fatty acids, esters, alcohols and other metal soaps, etc..
Antiwear extreme pressure agent: double row angular contact ball bearings are anti-wear extreme pressure agent most strong chemical activity of organic compounds, such compounds at room temperature when not afford lubricating effect on the metal surface, while at high temperature can be 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 the role to prevent abrasions.
