Automatic lubrication systems have some big benefits.
For one, the grease is evenly distributed on the wear surfaces of each pin and bushing. This drastically extend the life of these components.
And automatic greasing systems are highly precise. They apply just the right amount of lubrication to the machine, and won’t go overboard and apply too much grease.
Automatic lubrication is also highly efficient. Not only do they not provide too much lubrication, but they also use less grease than if a machine was lubricated manually by hand with a grease gun. This also saves on downtime.
It also improves the health of a machine by creating mini “grease donuts” around each pin. This keeps contamination out of the lubrication point.
And each lubrication point gets just the right amount of grease, in line with how much it needs. An excavator’s bucket pins, for example, need up to 25 times the amount of grease than a boom cylinder pin needs on each system cycle.
