Automatic Four Ball Wear Friction Tester Popular in Europe and Middle East

Automatic Four-ball Lubricant Tester is a floor-standing instrument designed and manufactured to determine the Extreme-Pressure Properties, the Wear Preventive Characteristics and the Coefficient of Friction of Lubricants. It has been widely applied in Tribology Research Laboratories and in the routine quality control of finished lubrication products.

We have exported our Automatic Four Ball Wear Friction Tester to Europe and Middle East and got a good score in customer’s supplier evaluation, like product quality, price and service,etc.

Automatic Four Ball Wear Friction Tester can meet ASTM standards:

ASTM D2596-20 “Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method)”;

ASTM D2783-21 “Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Fluids (Four-Ball Method)”;

ASTM D2266-01(2015) “Standard Test Method for Wear Preventive Characteristics of Lubricating Grease (Four-Ball Method)”;

ASTM D4172-20 “Standard Test Method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method)”;

ASTM D5183-21 “Standard Test Method for Determination of the Coefficient of Friction of Lubricants Using the Four-Ball Wear Test Machine;

Automatic Four-ball Lubricant Tester is mainly used for the determination of the load-carrying properties of lubricating greases & fluids, extreme-pressure properties of lubricating fluids; including last nonseizure load (PB), weld point (PD), combined wear number (ZMZ) and other data.

It is also suitable for the determination of the coefficient of friction, real-time display curves of friction and its coefficient. With high-precision measuring digital camera system, scar could be enlarged to be shown on computer screen and analyzed via data processing software.
