Airline - Model BLG-30 -Lubricator

The obvious result of insufficient oil is frictional wear. The Piston in the average Rock Drill reciprocates about 1800 to 2000 times per minute. Other internal parts move at corresponding friction produces heat, and this is the factor that causes real trouble/Despite fine metallurgy, lack of oil can produce heat; sufficient to cause minute surface cracks that may result in complete breakage of the parts. Hence use of Airline Lubricators, which are designed to provide sufficient lubrication to ensure smooth working and prevent frictional wear on Piston.
