The manual lever style grease gun is the most common. A typical, off-the-shelf shop gun can produce 7,500 to 15,000 psi. This can make the gun dangerous for bearing seals if misused. They typically hold 14oz (400gm) cartridges and produce various quantities/stroke.
How much PSI does a grease gun have?
A high-pressure manual grease gun is designed to deliver from 2,000 to 15,000 psi. Applying too much pressure while greasing will damage the bearing seals, which rarely handle more than 500 psi.
How much pressure can a grease fitting hold?
Grease guns are also capable of producing 15,000 – 20,000psi per stroke. Pressures like this are capable of blowing out bearing, and a careless approach can result in over lubrication resulting in a bearings life-cycle being significantly reduced. Over greasing of bearings is far more common than under greasing.

How much grease does a grease gun pump?
Generally, a shot of grease means one stroke from the grease gun. However, the output, or amount of lubricant dispensed from a grease gun depends on the model. Grease guns deliver widely varying amounts of grease (typically 0.1 ounce or 2 to 3 grams).
How many cc's are in a pump of grease gun?
Gun grease gun dispenses a theoretical 3cc per stroke. Our tests confirm the actual volume dispensed is 2.7cc/stroke.
Is an electric grease gun worth it?
An electric grease gun is a useful tool for those who operate heavy equipment and machinery. The gun injects heavy lubricating grease into machine parts and can be used with ease on both light and heavy equipment. Electric grease guns are generally more affordable than pneumatic guns, but do not create as much noise.
Where are alemite grease guns made?

What is the maximum pressure that a hand lever grease gun can dispense?
A high-pressure grease gun delivers pressure up to 15,000 psi. Most bearing seals will rarely handle more than 500 psi. A grease gun in the hands of an untrained technician can compromise the bearing’s seal and lead to early failure.
Do grease guns go bad?

Can you grease a pump while it's running?
Care must be taken to follow the simple rule of 1-2 seconds between grease gun strokes and to grease while the motor is running. NEVER use an electric grease gun to grease an electric motor. A disadvantage of shielded bearings is an increase in friction and temperature of the bearing.
How do you know when a grease fitting is full?
If this is the case, the best tactic is to “feel” the grease into the bearing cavity until slight resistance or back pressure is felt against the trigger, or lever, signaling the bearing cavity is now full.
Are there different size grease gun couplers?
Grease fittings come in many different styles. There are two grease fittings that are very common. These are the 1/4″-28 thread and the 1/8″ NPT thread. However, there are other less common grease fitting threads in use.
Why is the M3 called a grease gun?
The M3 was commonly referred to as the “Grease Gun” or simply “the Greaser”, owing to its visual similarity to the mechanic’s tool. The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944.

How many pumps does it take to accumulate 1 fluid ounce of grease from a grease gun?
Pump one fluid ounce(six pumps of hand pump grease gun) of grease into the fitting located nearest the leading edge of the blade on a tractor installation or nearest the trailing edge on a pusher installation, until grease emerges from the hole where the fitting was removed.
How does a gravity feed lubrication system work?
Drip feed systems, also referred to as gravity feed systems, consist of a loosely covered cup or manifold of oil placed above the bearing that meters out oil at a set interval. The supply to the bearing is controlled by a needle or conical valve, and can be adjusted as necessary.

How do you store a grease gun?
New grease cartridges or tubes should be stored upright (vertically) with the plastic cap up at all times. This will help to prevent oil from leaking out of the tube. If the cartridge is left in a grease gun, the gun should be depressurized and stored in a horizontal position inside a clean, cool and dry area.
Does anyone make a grease gun that works?
Best Electric Grease Gun—Lumax Cordless Grease Gun Another great tool by Lumax is the LX-1175 Handyluber; a lightweight, electric grease gun operated by a 12V battery that can deliver up to five cartridges of grease on one charge.
Why is it called a grease ZERK?
The Zerk design, named after Oscar Zerk, used a fitting much smaller than the Alemite pin-type and did not lock the hose coupler or hand gun and fitting together. Instead, the seal between them was maintained by the pressure of a pushing action when the operator applied the coupler to the fitting.
What does ZERK mean?
zerk in American English (zɜrk ) noun. a small metal fitting through which grease can be inserted into a mechanical joint that requires periodic lubrication.
What is a button head grease fitting?
Button head grease fittings are a heavier duty fitting distinguished by its flat, low profile appearance. They are able to handle large grease volume due to their high flow rate and sturdy construction. Button head fittings feature a smooth working surface and allow for easier coupler attachment and removal.
Why does my grease gun leak?
Gravity, shearing and vibration are all forces that can separate oil from a grease thickener. It happens in a machine when moving parts shear through the grease to release oil into contact points. … If that low point is not a sealing surface, oil can leak away from the machine, grease tube or even a grease gun.
How do you fill a push type grease gun?
8oz Push Type Mini Grease Gun: Designed with a push-action technique, simply push the pump down to force grease from nozzle. This compact design holds up to 8oz of grease. To fill with grease, simply unscrew the base cap and load up the body with new grease.
Can you leave grease in a grease gun?
It is acceptable to leave unused grease in a grease gun. It is recommended to release the pressure from the grease by drawing the handle back and locking the spring in the retracted/compressed position.
Can bearings be over greased?
When it comes to regreasing bearings, more is not always the better option and actually can be a costly mistake. … Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.
How often should you grease a motor?
In general, for oil bath lubrication where the operating temperature is 50°C (120°F) or less, oil should be replaced once a year. When the operating temperature is between 80°C – 100°C (176°F – 212°F), oil should be replaced at least every three months.
Should sealed bearings be greased?
Sealed bearings are generally only used for lower speed motors, 75 hp and under, and have an anticipated life span of only three years. These types of bearings fall under the “Lubricated for Life” designation and do not require regreasing.
