Product Details
1、 Product Introduction:
Electro hydraulic servo typeFour ball friction testing machineThe bearing capacity of lubricants is mainly evaluated in the form of sliding friction under extremely high point contact pressure conditions. Including maximum non card bite loadPBSintering loadPDComprehensive wear valueZMZWait for three indicators. This four ball friction testing machine can also perform long-term wear resistance tests on lubricants, measure friction coefficients, and record friction and temperature curves. The electro-hydraulic servo type four ball friction testing machine can be equipped with a high-precision measuring device, which can realize the calculation screen display, measurement, and recording of friction pair friction spots.Special attachments can also be used for simulating end face wear and material testingThe appearance reference image is shown in the above figure.
