Reciprocating Tribometer
The Reciprocating Tribometer is a value-engineered tribological testing instrument designed for lubricated ball-on-flat experiments. You can perform high-frequency linear oscillation tests to evaluate friction, wear, and extreme pressure (EP) properties of lubricating greases, oils, and solid bonded films. The instrument combines a servo-pneumatic loading system, Scotch Yoke reciprocating mechanism, and touch-screen PC control for precise management of load, stroke, frequency, and temperature. You can collect real-time friction data via a piezoelectric transducer and export all test results for analysis.
