NPK AUTOLUBE SYSTEMS are designed to automatically provide a supply of grease to the hammer tool bushing - increasing tool bushing life by reducing tool bushing wear.  NPK offers both carrier mounted and hammer mounted options.  Due to its compact design, the hammer mounted autolube system can be installed directly onto the hammer. This design ensures that the autolube system is always with the hammer, great when sharing a hammer between several carriers.
