产品简介

Bjms-10a microcomputer controlled four-ball friction testing machine is mainly based on sliding friction, which can be used to evaluate the bearing capacity of lubricants under extremely high point contact pressure conditions.It includes three indexes, namely, the maximum unclamped load PB, the sintering load PD, and the comprehensive wear value ZMZ.The machine can also be used as lubricant for long time wear resistance test, determination of friction coefficient, recording friction and temperature curve.The machine is equipped with a high precision measuring device, which can be used to measure the spot size of the friction pair, or to display, measure and record the computer screen of the friction pair.
