MRS-10A microcomputer control four-ball friction tester

MRS-10A microcomputer control four-ball friction tester
 

Product description:

MRS-10A microcomputer control four-ball friction tester
It is mainly in the form of sliding friction, assessing the carrying capacity of lubricants at very high pressure conditions point contact, including the three largest non-card bite load indicators PB, sintering load PD, comprehensive wear value ZMZ and so on. The machine is also Anti-lubricants can do long-wear test to measure the coefficient of friction, friction and temperature curves recorded. The machine is equipped with high-precision measuring devices to measure friction wear scar size, or achieve friction wear scar computer screen display, measured and recorded.

This machine is suitable standards:

GB / T12583-98 Determination of lubricant extreme pressure properties (Four-ball machine method)
GB3142-82 Determination of carrying capacity lubricant (Four-ball method)
SH / T0189-92 Determination of anti-wear performance lubricants (four-ball machine method)
SH / T0202-92 Determination of grease extreme pressure properties (Four-ball machine method)
SH / T0204-92 Determination of grease abrasion resistance (four-ball machine method)
