The expiration date will vary depending on the thickener. For example, lithium grease is often identified as having a 12-month shelf life, while calcium-complex greases may have a shelf life of just six months – and this is under good storage conditions.
Can I 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.
Does grease go bad with age? “Lubricant deteriorates over time as a result of aging, condensation, and separation of the oil and thickener. For closed bearings – sealed or shielded – that contain the standard domestic grease (GJN), and that are still in their original, unbroken packaging, the recommended shelf life is five years.
Does mechanical grease go bad? Unused lubricating grease can “go bad” if it is stored for an excessively long period of time, or under poor storage conditions. … Both the oil and solids separation phenomena can be aggravated by the improper storage of the grease container in direct sunlight or near a heat source.
Do grease guns go bad? Re: Frustrated with Grease Guns If you buy a good one it will last a life time. A new whip hose and tip every once in a while. The Lincoln I have is at least 35 years old.

What happens to bearing grease over time?
Grease made from low-viscosity base oils is at the highest risk of volatilization. At sufficiently high temperatures, oil can boil out of the thickener matrix, causing hardening of the grease over time (lower oil-to-thickener ratio and higher base-oil viscosity).
What do I do if my grease fitting won’t take grease?
Grease made from low-viscosity base oils is at the highest risk of volatilization. At sufficiently high temperatures, oil can boil out of the thickener matrix, causing hardening of the grease over time (lower oil-to-thickener ratio and higher base-oil viscosity).

How do you keep grease from separating?
What can I do to prevent the grease from separating or bleeding? First, when you’re finished greasing, level the grease surface before placing the container back in storage. Second, try to store your greases away from heat and cold sources or in areas where temperature fluctuations are common.
Why do grease guns 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.
What causes oil separation in grease?
Oil separation can occur when the oil is exposed to heat over a long period of time, when the pail is stored in a hot storage environment, when the grease surface is uneven or when the pail is exposed to pressure and altitude changes.
Why isn’t my grease gun pumping?

What is the shelf life of bearing grease?
Lubricant deteriorates over time as a result of ageing, condensation, and separation of the oil and thickener. Therefore, sealed bearings should not be stored for more than three years.
Does compressor oil go bad?
Oil ages when not changed regularly. As it goes bad, its viscosity lessens because of its exposure to a lot of cooling and heating cycles. Because of friction, the environment inside the compressor becomes too humid that the grease liquefies and this will further make it lose its ability to lubricate.
What is lifetime lubrication?
There’s no standard definition of “lubricated for life,” since life can vary, depending on the product and application. The simplest explanation of “lubricated for life” is a linear bearing (or ball screw) that does not need re-lubrication over its normal service life.
What does the color of grease mean?
Dark blue – typically for multipurpose greases made from conventional oil base stocks. Red – mostly for multipurpose synthetic greases. Grey – for those containing moly for many off-road equipment specifications, and. White or undyed greases – typically used in paper machines or food-grade applications.
What is the difference between red and green grease?
Although there is no hard and fast rule, red could be indicative of grease for high temperatures, blue for cold temperatures and green for environment friendliness.
Why did grease turn black?
How can grease color affect performance? … It may either lose color or become darker to black. These color changes can occur due to thermal degradation, oxidation, or contamination. High temperatures can cause the dyes to lose color intensity while highly oxidized greases may blacken with use.

Can you put too much grease in a bearing?
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 bearings?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months, you could average it out to a stroke every 8 weeks or so.

What is oil bleeding?
Oil bleed is a term used to explain the separation of oil or seepage of oil during normal grease operating conditions. The lower the viscosity of the base oil used in the grease, the more separation you are likely to see.
Does grease turn into oil?
At room temperature, greases are usually solid, while oils are usually liquid. All oils can be turned into greases, but not all greases come from oils. Greases are typically only used on machinery, tools, or equipment, while oils have a multitude of other, non-industrial uses.
How do you store grease?
Instead, store the grease in the refrigerator (up to 3 months) or freezer (indefinitely). The refrigerator is best because the fat will stay soft enough to scoop, so you can have delicious solid drippings at the ready.
