HST-MRS10D Computer Control Servo Four Ball Friction Testing Machine
1.Application
This machine mainly uses the form of sliding friction to evaluate the bearing capacity of lubricant under extremely high point contact pressure conditions. There are three indexes including maximum non-clamping load PB, sintering load PD and comprehensive wear value ZMZ. The machine can also do lubricant long - time wear resistance test, measurement of friction coefficient, record friction and temperature curve.
2. Standard
GB/T12583-98 Lubricants -- Determination of extreme pressure properties (four-ball machine method)
GB3142-82 Lubricants -- Determination of bearing capacity (four-ball method)
SH/T0189-92 Lubricating oil -- Determination of anti-wear properties (four-ball machine method)
SH/T0202-92 Test method for extreme pressure performance of greases (four-ball machine method)
SH/T0204-92 Test method for wear resistance of greases (four-ball machine method)
