What type of grease for bearings

Barium complex grease is a high-performance grease widely known for its mechanical stability, high-temperature resistance, ability to withstand heavy loads and high speeds, excellent water tolerance, great oxidation stability, as well as resistance to various chemicals.

Barium complex grease is mostly used in demanding, heavy-load applications, such as industrial, aeronautical, marine, and manufacturing applications. Bentone grease is a clay-based lubricant developed with the help of bentonite clay.

This grease type is often called non-melt lubricant because it has no known dropping point. Its main properties are temperature change resistance, great wear and tear protection, exceptional water tolerance, good mechanical or shear stability, and impressive adhesiveness. Polyurea grease has become very popular due to its amazing characteristics, such as outstanding water resistance, great oxidation stability, rust and corrosion prevention, durability, versatility, good mechanical stability, as well as high-temperature performance.

Due to these features, polyurea grease is recommended for long-life applications and used across various industries. It is considered vital for proper lubrication of steel plants and electric motors. Sodium grease is formulated by mixing soda soap with additives and base oils. Such mixture provides solid shear stability, high dropping point, excellent rust protection, and good lubrication, but has poor water resistance and oxidation stability.

Due to its drawbacks, sodium grease is now mostly used for lubrication of rolling contact bearings. Moreover, it is commonly mixed with other greases in an effort to produce grease of higher quality and value. All these seven types of grease can be referred to as multipurpose MP greases, extreme pressure EP greases, marine greases, heavy-duty greases, specialty greases, automotive greases, industry greases, and so on, depending on the unique properties of base oils, additives, and thickeners used in the process of manufacture.

Three main types of base oils are mineral, synthetic, and vegetable oils. The 0 rating indicates that the grease is soft, in an almost liquid-like consistency. Most wheel bearing formulas come with a rating of 2. This indicates that the consistency is similar to peanut butter. You can mix together some oils used in bearing grease.

For example, plant-based oil and petroleum-based oil can mix freely with each other. If you want to know if the new bearing grease will mix well with the old bearing grease, you can do some research. If you mix together two incompatible types of grease, your wheel bearings can fail. Mixing together two different types of soap can result in the soap separating from the oil.

This will render the grease useless. That means thoroughly removing the old grease before packing the new grease into the wheel bearings. Here are some liquids you can use to clean out the old grease:. In some situations, it can be hard to remove the old grease.

Just make sure the grease you used before is the same as the one you will be using. You can try to pump out the old grease with the new grease using a grease gun. The new grease will push out the old grease. We would love to hear your feedback! Contact [email protected] to share your thoughts! Share on Facebook. Share on Twitter. Share on Reddit. These additives can shorten the life of the grease and are not recommended for use where they are not required.

Dropping point: The dropping point is an indication of the temperature at which the grease will melt or the oil will separate from the thickener. A grease with a high dropping point is desirable, given the high temperatures reached during electric motor bearing operations. An electric motor bearing grease should soften no more than 1 to 1.
