Selecting the right grease is crucial to maximize the performance of your application. A proper grease product recommendation requires an extensive insight into all involved working elements:

• Operating temperature and conditions
• Load regime
• Rotation speed
• Type of application

Once all the above-mentioned parameters are determined, the following performance properties of the grease are used as selection criteria:

• Dropping point
• Water washout
• Pumpability
• Environmental friendliness

These properties are mostly defined by the application conditions: water, extreme pressure performance, steam, temperature, food industry, bio degradable, harsh conditions, …

 

For example, it is not necessary to use a high temprature grease when the bearing is mostly working at ambient temperature. And a light loaded high speed bearing does not need high performance EP additives. A good rule of the thumb is to use greases with higher NLGI grades for applications with higher speeds.
