MRS-10G lever type four-ball friction testing machine:It is a replacement product developed by our company that can replace the MRS-10D electro-hydraulic servo four-ball machine.It includes three indicators: non-seizure load PB, sintering load PD, and comprehensive wear value ZMZ.
This machine can also perform long-term anti-wear testing of lubricants and determine the friction coefficient.Friction force and temperature curves can be recorded after connecting to a computer.If special friction accessories are used, rolling friction tests, simulated wear tests between various materials, end face wear tests, and steel ball rolling fatigue tests can also be performed.
The lever-type four-ball friction testing machine developed and produced by our company can continuously load the test force. In addition to the test force level required by the standard method, the required test force can be set arbitrarily through the computer, fully achieving the functions of the electro-hydraulic servo four-ball machine.
