Grease Gun: Best-Practice Fundamentals for Use

Today, there are numerous technologies that are used for the re-greasing of machine components. One of the most popular tools used for this purpose is the grease gun. The reason for using the grease gun is to apply lubricant via an orifice to a certain point, and it is done with the support of a special fitting. Grease guns are built for numerous applications, and the most popular designs include pistol-grip, hand-grip, lever, battery-powered, and air-powered models. The lever design is the most affordable, and, therefore, the most popular among them.

A Vital Tool in Skilled Hands

One of the most underutilized and unessential tools in a maintenance workshop, one grease gun can cause the complete breakdown of an entire manufacturing facility if not used properly. An important step that is ignored is instructing the lubrication technician on the appropriate use of the grease gun. A high-pressure grease gun has the capability to deliver at most 15,000 psi of pressure. Have you imagined a scenario whereby you put a bearing on the shop surface and introduce 15,000 psi to the outer surface or race before proceeding with the new installation? A grease gun left in the hands of an unqualified technician will distort the bearing’s seal, resulting in an early failure of the machine.

Lubrication technicians must also know the total output in relation to the grease gun’s stroke so as to determine the total grease that will be needed for the lubrication of the equipment. Grease guns come in various ranges and differ in the amount of grease used per stoke, with different amount of grease. Some manufacturers will always include the strokes per ounce and maximum pressure on their manual. If it is not included, you can easily calibrate one by yourself. The items you need are the gun and a postal scale.

Another factor to take into consideration is the kind of grease fittings used in the workshop. The most popular fitting is the hydraulic fitting. These fittings come with a ball check positioned on the head of the fittings which obstructs dirt from affecting the bearing.
