This lubricator delivers a metered flow of grease to the central lubrication points on the host machine. It is a maintenance component that operates in the automatic lubrication system, supplying the correct quantity of lubricant to bearings and pivot joints at programmed intervals. A failed or blocked lubricator causes under-lubrication of critical joints, leading to accelerated wear and eventual seizure of the moving assembly. The original part maintains the calibrated delivery volume and cracking pressure that the system controller expects, so replacement with a non-calibrated unit can disrupt the lubrication cycle. When replacing, purge the supply line of air and verify the output at each distribution port before returning the machine to service.
