The HSD is a twin-disc tribometer designed to measure friction in non-conformal contacts at surface speeds up to 60 m/s.
The HSD is a twin-disc instrument designed for high-speed testing of friction and wear in non-conformal contacts. It reaches surface speeds up to 60 m/s and offers full control over load, slide-roll ratio, and temperature. With continuous wear monitoring, high-resolution traction measurement, and a configurable five-port test chamber, the HSD enables precise emulation of demanding applications such as EV transmissions and high-speed rotating machinery. It provides a platform for the development, validation, and characterisation of lubricants, additives, and materials under extreme operating conditions.
