ASTM G99 Pin On Disc Tribometer Wear Testing Machine (RT-228)
Multi-Specimen Four Ball Vertical Universal Wear Tester
This machine selects different friction vice forms for testing under certain contact pressure in the form of sliding, rolling, and compound friction so as to evaluate the long-time anti-wear performance of lubricating oil and grease, as well as the friction and wear performance of metal materials.
Product Details：
RT-228 Multi-Specimen Test Machine is a sliding, rolling, and composite friction form under a certain contact pressure; choose different forms of friction vice for testing so as to evaluate the long-term anti-wear performance of lubricating oil, grease and friction and wear performance of metal materials. The machine is equipped with three kinds of friction parts, such as four balls, a pin disc, a thrust ring, etc. According to the user’s demand, it can provide as many as seven sets of 10 kinds of friction parts and non-standard customized friction forms, such as ball disc, ball – three pieces, and pin – three columns. The machine can measure the friction torque, calculate the friction coefficient, connect to the computer and record the temperature-time curve and friction coefficient-time curve. It can be equipped with a high-precision measuring device, which can measure the friction vice wear spot size, sense of realization of the friction vice wear spot of the computer screen display, measurement, and recording.
The machine can completely replace the U.S. FALEX-6 type testing machine, and the specimen with the same type of equipment in the United States specimen common, can successfully complete a variety of tests. According to the user demand part of the test function can be customized.
Product Features:
1. Low-speed pin disc (with large and small discs, single pin and three pins) friction function, four-ball long-time anti-wear performance and four-ball rolling contact fatigue, ball a bronze three-piece lubrication performance, as well as thrust washer, ball a disc, mud wear, rubber seals, lip sealing torque and stick-slip friction performance of the test, matched with the reciprocating module can be realized by the reciprocating friction and wear movement.
