Journal Bearings and Their Lubriion

Grease is used to lubrie journal bearings when cooling of the bearing is not a factor, typically if the bearing operates at relatively low speeds. Grease is also beneficial if shock loading occurs or if the bearing frequently starts and stops or reverses direction.

The M&E Guide to Grease | Maintenance and Engineering

19/2/2019· The M&E Guide to Grease. The word “grease” comes from the Latin word “crassus” meaning “fat”, which effectively describes its consistency. It is believed that around 500BC the ancient Egyptians were among the first to develop a real grease by coining olive oil with lime (calcium), which acted as a thickening agent.

Types of Bearings and Thier Appliions

25/5/2019· Fluid Bearings are bearings in which the load is supported by a thin layer of rapidly moving pressurized liquid or gas between the bearing surfaces. Since there is no contact between the moving parts, there is no sliding friction, allowing fluid bearings to have lower friction, wear and vibration than many other types of bearings.

Disadvantages of grease used

In General, ordinary mineral oil grease only allows use of conveying speed of a DN value (the inside diameter of the bearing MMX turn speed r/min) is less than 300000mm • r/min. With the development technology of lubriing greases, synthetic lubricants can be used to 500,000 ~60 DN value, or even 1 million.

How to Choose the Best Grease for Your Heavy Equipment | …

30/8/2019· Don''t overuse the grease gun on the bearings—Grease guns produce up to 15,000 psi per stroke (or shot), but a bearing lip seal can only handle up to 500 psi. If you apply, say, 20 shots of grease to a bearing, you may overfill the bearing cavity, which can force the grease outside of the seals when the equipment heats up.

Determine Grease Consistency | Nye Lubricants

A grease with an NLGI grade of 1 has a consistency like tomato paste, where a grease with an NLGI grade of 3 has a consistency more like butter. The most commonly used greases, such as those used in automotive bearings, would use a lubricant that is NLGI grade 2, which has the stiffness of peanut butter. Grades within this range can operate in

Understanding technical data of greases | SKF | SKF

A measure of the stiffness of a grease. A proper consistency must make sure that the grease stays in the bearing without generating too much friction. It is classified according to a scale developed by the NLGI (National Lubriing Grease Institute). The softer the grease, the lower the nuer. Grease for bearings are typically NLGI 1, 2 or 3.
