Product Description

Main Application

This machine determines the bearing capacity of lubricant in form of sliding friction under much high point contact pressure, including maximum non-seizure load PB, sintering load PD,composite wear value ZMZ etc. This machine can do lubricant long time wear resistance test to determine the coefficient of friction.

 

Applicable Standards

GB/T12583-98 lubricant extreme pressure performance measurement (four ball machine method)

GB3142-82 lubricant bearing capacity measurement method (four ball method)

SH/T0189-92 lubricant anti-wear performance measurement (four ball machine method)

SH/T0202-92 extreme pressure grease performance measurement (four ball machine method)

SH/T0204-92 grease anti-wear performance measurement (four ball machine method)
