Product Description

ASTM D2596 D2783 D2266 D5183 D4172 Four-Ball Extreme Pressure Test Machine
 
Introduction:
 The Automatic Four-Ball Extreme Pressure Test Machine is a floor standing instrument designed to determine the friction properties of extreme pressure oils and greases. It has been applied in tribology research laboratories and in the routine quality control of finished lubrication products.

The Automatic Four-Ball Extreme Pressure Test Machineis designed and manufactured strictly according to the following ASTM standards:
 ASTM D2596-15 "Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method)"; ASTM D2783-03(2014) "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 D5183-05(2016) "Standard Test Method for Determination of the Coefficient of Friction of Lubricants Using the Four-Ball Wear Test MachineASTM D4172-94(2016) "Standard Test Method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method)"
 The Automatic Four-Ball Extreme Pressure Test Machine can be used for the determination of wear preventive characteristics of lubricating oils and the measurement of extreme-pressure properties of lubricating fluids; including the maximum no clamping load PB, the sintering load PD, the comprehensive wear value of ZMZ and other three indicators. It is also suitable for long-term wear resistant test, determination of the friction index, real time curve of friction and record of friction force. With high precision measuring digital microscope, friction grinding spot and friction wear spot can be enlarged to be shown on computer screen and analyzed via data processing software.
