An automatic lubrication system sometimes referred to as a centralized lubrication system, is a system that delivers controlled amounts of lubricant to multiple locations on a machine while the machine is operating. Even though these systems are usually fully automated, a system that requires a manual pump or button activation is still identified as a centralized lubrication system. The system can be classified into two different categories that can share a lot of the same components.
Oil Systems: Oil systems primary use is for stationary manufacturing equipment, such as CNC milling.
Grease Systems: Grease's primary use is on mobile units, such as trucks, mining or construction equipment.
