Lubricants can be used interchangeably

Thread Content

Depending on the operating conditions of the equipment, the working environment, the specific characteristics of the friction surfaces, and the lubrication method, the type and grade of lubricating oil used also vary: for equipment with high rotational speeds, where oil films are formed and strong lubricating effects are required, lubricants with low viscosity should be used； When the load per unit area on the friction surfaces of the equipment is high, lubricants with high viscosity and good oiliness should be used ； When the operating environment of the equipment is at high temperatures, lubricants with higher viscosity, higher flash point, better oiliness, and greater stability, or greases with a higher consistency, should be used ； The smaller the gap between the friction surfaces of the equipment, the lower the viscosity of the lubricating oil that should be used ； The friction surface is relatively rough; the higher the viscosity of the lubricant chosen, the greater its working cone angle should be if grease is used ； In pressure cycle lubrication, where the oil temperature is high, lubricants with higher viscosity should be used.
