High Frequency Reciprocating Rig – HFRR-1000

The HFRR Tester (High Frequency Reciprocating Rig) is a precision fuel lubricity, friction, and wear tester designed for standardized and advanced tribology testing of fuels and fuel additives.

The HFRR provides real-time programmable load control without dead weights, delivering precise and repeatable test conditions. A voice-coil actuator provides programmable oscillation from 1–200 Hz, while the 10 µm–2.8 mm stroke range enables both standard lubricity testing and advanced research.

High-sensitivity piezoelectric force sensors provide real-time friction measurement and detailed monitoring of contact behaviour. The system supports ASTM D6079 and ISO 12156 fuel lubricity testing, with automated, recipe-based test control and reporting.

Beyond standard HFRR testing, the system offers custom test methods, electrified testing, extended load and stroke ranges, and additional sensor options, making it suitable for fuel formulation, additive development, lubricant research, friction and wear studies, and quality control.
