STANDARD TEST – TWIST COMPRESSION TESTER

Beskrivning

The ST-TC test machine is designed for running tests in accordance with the ASTM G223 standard

for evaluating the friction and adhesive wear properties of materials under both dry and lubricated

conditions. This test bench ensures reliable, standardized testing and facilitates comparative wear

performance analysis for end users.

The machine is equipped with a manual hydraulic pump and cylinder for loading, with a force

transducer for load measurement. A high-torque, low speed, gear-motor, with encoder feedback,

provides rotation of the upper specimen. The lower specimen is torque reaction mounted, with a

lever arm that engages with a load cell for friction torque measurement.

The machine frame is designed to be sufficiently rigid to prevent deflection under high test loads.

It features self-aligning mechanisms to ensure horizontal and concentric alignment of the

contacting specimen surfaces.
