Grease is used to lubricate glass stopcocks and joints. Some laboratories fill them into syringes for easy application. Two typical examples: Left - Krytox, a fluoroether-based grease; Right - a silicone-based high vacuum grease by Dow Corning.
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.
Grease compatibility charts have been developed and circulated since the 1980s without much alteration. However, grease technology has changed significantly over the years, and there are many examples of performance that contradict several widely used compatibility charts.
Charts from Lubritene and Transit Lubricants indicate that “Polyurea” grease is BORDERLINE COMPATIBLE with Calcium Complex. A chart provided by Amsoil shows both “Polyurea
19 sie 2024 · This involves a comprehensive analysis of whether using the grease extends the lubrication cycle, the number of grease additions, grease consumption, bearing failure rate, and maintenance costs, among other factors.
12 kwi 2024 · What are Specialty Greases? 7 Types of Grease. Grease is a crucial lubricant used in various industries and applications, providing protection against friction, wear, and corrosion. There are different types of grease available, each with its own unique properties and uses.
17 lut 2017 · February 17, 2017 - NLGI Grade. A numerical scale for classifying the consistency of lubricating greases, based on the ASTM D217 worked penetration at 25°C (77°F). NLGI Grades are also referred to as NLGI Consistency Numbers or NLGI Numbers. In order of increasing consistency (hardness):
