FRICTORON | friction and wear tester

• Friction and Wear Tester for Tribology Evaluation
  The EFM-III series is a friction and wear tester for tribology evaluation in conformity with JIS K 7218. This tester is designed for scientific elucidation and technical evaluation of the characteristics relating to sliding friction, wear and lubrication, that are surface behaviors of relative properties of two interacting material surfaces (relative properties of solid materials in relative motion). To calculate the friction coefficient (µ), the EFM-III series detects a shear force, as a friction force (F), by applying rotational sliding movement to a test piece at a set pressure load (P) and a set sliding velocity (V). In addition, after an evaluation of the PV limit value and a long-time sliding test, the EFM-III series measures the decrease in weight or dimension of the test piece to evaluate its wear resistance.
