Bearing Lubrication. Download PDF of this information. The Role of Bearing Lubricant. Bearing Lubrication plays a vital role in the performance and life of rolling element bearings. The most important task of the lubricant is to separate parts moving relative to one another (balls or rollers and raceways) in order to minimize friction and prevent wear.
Types of grease and grease selection Types of grease and grease selection . Posted : 2/19/2016. Category : Industrial application expertise ... From extending regreasing intervals at a plant from weekly to quarterly, to extending the life of machine bearings, synthetic grease can improve industrial operations and help to cut costs for operators.
The consistency of grease depends on the percentage of soap, or thickener in the grease. It is obtained by measuring in tenths of a millimeter, the depth to which a standard cone sinks into the grease in five seconds at a temperature of 25 Â°C. When choosing a grease consideration must be given to circumstances and nature of use.
It is important to note that the viscosity of a lubricant will decrease as the temperature increases. Viscosity Index (VI) is an arbitrary scalar value that indicates the change in an oilâ€™s viscosity with
Welcome to the world of Barden Precision Bearings. For over 100 years Barden/FAG has been a global leader in the development of precision bearing technology.

Basic bearing grease selection With additional information like speed, temperature, and load conditions, LubeSelect for SKF greases is the easiest way to select the right grease. For additional information, visit www.aptitudeexchange.com. Additionally, the SKF bearing grease selection chart provides you with a complete overview of SKF greases.
Grease (lubricant) Although the word grease originally described the rendered fat of animals, the term is now applied more broadly to mean a lubricant of higher initial viscosity than oil, consisting originally of a calcium, sodium or lithium soap jelly emulsified with mineral oil.. Properties. A "true" grease consists of an oil and/or other fluid lubricant that is mixed with another thickener ...
Q: I shot a bunch of expensive marine-style grease into the bearing buddies on my bass-boat trailer last fall. It was recommended to me by a marine mechanic as the best product for my trailer ...
Recommended for food processing industry appliances that need excellent mechanical function in very humid environments. Being formulated with complex calcium sulfonate soap and semi-synthetic oil means it performs exceptionally in load-bearing work, demonstrating a high lubricating and anti-oxidant capacity.

bearing, a grease with a high dropping point is frequent-ly desirable. Lithium-complex greases and polyurea-thickened greases both have dropping points of approx-imately 500Â°F or higher. ExxonMobil Guide to Electric Motor Bearing Lubrication The proper lubrication of electric motor bearings is essential
Because the majority of grease-lubricated applications are element bearings, one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing, many people will use a grease containing that same oil for an identical grease-lubricated bearing. There are ...

An electric motor bearing ... eventually increases the oil viscosity and hardens the soap. Some oil bleeding is desirable, but too much reduces the ...
For many years a standard Lithium based grease has been the lubricant specified for use in DC motor bearings. With the trend toward the replacement of DC traction motors with AC motors, NSK has been instrumental in the development of a lithium-complex soap grease to achieve longer life.
Bearing grease is composed of a base-oil, a thickening agent and additives.Specific base-oils are designed to handle certain applications and environments: Thickening agents within grease manage the â€śbleed-rateâ€ť by releasing or retaining the base-oil.Some grease thickeners are

High temperatures can cause grease to bleed (purge the oil), which reduces the lubricantâ€™s efficiency. In elevated temperature conditions, oxidation can lead to the loss of lubricating oils from the grease, leaving a dry, crusty soap that can seize the bearing. Higher temperatures also reduce the hardness of the metal, causing early failure.
