Bearing Lubrication and the Reasons for Lubrication
There are four functions a lubricant must perform to ensure that a bearing will provide good service:
Maintain an unbroken film between metal surfaces.
Prevent excessive friction and the resulting increase in temperature.
Conduct heat away from the bearing’s surfaces.
Remain stable under severe operating conditions.
Severe operating conditions are temperature, humidity and vibration.
The right selection of a lubricant is usually based on four conditions;
Any one of these is crucial in any application. Of the four, the environment of the application is the most variable. When equipment is used outdoors or in a factory setting, which they may be exposed to dust, water, chemicals.
Load , speed and temperature are pretty much related. If the load or speed increases, the temperature of the bearing also increases. Only when the internal temperature of the bearing is extremely hot, then the type of lubricant may be different.
The kind of lubricant is also based on what type of bearing you are using;
journal, ball, roller or others. Most lubricants are interchangeable.
