Rtec Micropitting Tester MPT-3000: Next-Generation Triple Disk Roller Rig for High-Cycle Fatigue Analysis
The Rtec-Instruments MPT-3000 (also known as the Triple Disk Roller Rig) is an advanced, high-performance rolling contact machine specifically engineered to study micropitting, macropitting, traction, and wear under highly controlled sliding-rolling conditions. By utilizing a unique configuration where a central specimen is loaded against three symmetrically positioned outside rollers, the MPT-3000 can accumulate several million stress cycles in a remarkably short duration, making it the ultimate tool for accelerated life testing.
As the authorized distributor for LMS Scientific in Malaysia, we offer the MPT-3000 to local industrial laboratories, petrochemical refiners, automotive R&D departments, and academic institutions, fully backed by specialized regional technical service, calibration, and application support.

Key Functions & Core Benefits
- Accelerated High-Cycle Testing: The triple-disk roller geometry subjects the central pin or roller to three stress cycles per revolution, allowing researchers to complete long-term micropitting and fatigue protocols in a fraction of the time required by conventional twin-roller testers.
- High Torque & Independent Speed Control: Driven by high-torque servo motors (up to 60 Nm) that ensure smooth rotation and precise speed control across wide operating limits. It supports highly adjustable sliding/rolling ratios (SRR) from -200% to +200%.
- Advanced Multi-Sensor Diagnostics: Integrates highly sensitive in-line tracking sensors—including Acoustic Emission (AE) to capture micro-crack propagation and sub-surface pitting onset, and Electrical Resistance mapping to evaluate protective fluid film thickness and breakdown thresholds.
- Versatile Environmental Control: Enables precise simulation of severe industrial and automotive operating climates with integrated heating and cooling modules supporting dry testing or fluid immersion from -35°C up to 150°C.
Targeted Industrial Applications in Malaysia
- Electric Vehicle (EV) Powertrains: Screening specialized low-viscosity e-fluids, e-axle lubricants, and materials designed to resist high-speed rolling-sliding contacts under unique electric drive configurations.
- Industrial & Automotive Gear Oils: Evaluating the anti-pitting performance, surface fatigue limits, and extreme pressure (EP) additive efficiency of industrial gear oils, transmission fluids, and hydraulic fluids.
- Railway & Steel Rolling Mills: Modeling heavily loaded contact mechanics to study wheel-rail friction variations, corrugation, and advanced steel surface treatments under cyclic stress fatigue.
