Product description:

MRS-10D microcomputer control four-ball friction tester
The main purpose
It is mainly in the form of sliding friction point contact at very high pressure conditions used to assess the carrying capacity of the lubricant, including the largest non-card bite load P B , Sintering load P D When the anti-lubricant can also be long wear test, measure the friction, the friction coefficient calculated using special accessories, can also be simulated face wear and abrasion test materials; comprehensive wear value ZMZ and other three indicators.
