MR-S10   Series Four Ball Friction Testing Machine

I、Product introduction

1. MR-S10 series four ball friction testing machine is mainly used to evaluate the bearing capacity of lubricants in the form of sliding friction under extremely high point contact pressure. It includes three indexes: maximum non seizure load Pb, sintering load Pd and comprehensive wear value zmz. In practical application, different evaluation indexes can be selected according to various uses of lubricants.

2. The four ball friction testing machine is strictly produced in accordance with JB / T 9395-2004 technical conditions for four ball wear testing machine. It adopts computer full digital control mode. It can do long-term wear resistance test of lubricant, measure friction coefficient and record friction and temperature curve.

3. Applicable standards of this machine:

1) GB/T12583-98   Determination of extreme pressure properties of lubricants (four ball machine method)

2) GB3142-82       Test method for bearing capacity of lubricants (four ball method)
