Automatic lubrication system

An automatic lubrication system (ALS), often 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 primary use is on mobile units such as trucks, mining or construction equipment.

Oil vs Grease can very even though their primary use is mostly stationary for oil and mobile for grease, some stationary manufacturing equipment will use grease systems.
