• Pin on Disc Tester

Pin on Disc Tester



Determines the wear of materials during sliding using a pin-on-disc apparatus. Materials are tested in pairs under nominally non-abrasive conditions.

  • Conforms to ASTM G99 standard test method
  • Analyzes wear and friction characteristics of sliding contacts (dry or lubricated conditions)
  • Tests can be performed on a variety of materials: metals, polymers, composites, ceramics, lubricants, cutting fluids, abrasive slurries, coatings, and heat-treated samples
  • Data aquisition software package varies and records pin pressure, pin temperature, sliding speed, and lubrication parameters
  • Custom configurations available

Data Acquisition System incorporates sensor and signals with a combination of data acquisition hardware and software to create a complete measurement system. Our Pin on Disc Testers measures Real Time Data of physical properties of test materials. Friction, Wear, and Temperature can be analyzed and correlated with different test materials. The Koehler Pin on Disc Tester is primarily intended for determining the tribological characteristics of a wide range of materials under various conditions of normal loads and temperatures. A stationary pin mounted on a holder is brought in contact against a rotating disc at a specified speed. As the pin is sliding, the resulting frictional force acting between the pin and disc is measured. Both normal load and speed can be set as desired.
