Rtec MPT-3000 Micropitting Tester: Advanced Triple-Disk RCF Analysis
The Rtec Instruments MPT-3000 (Triple Disk Roller Rig) is a premier rolling contact machine engineered for high-precision studies of micropitting, macropitting, traction, and wear under controlled sliding-rolling conditions. Featuring a unique geometry where a central specimen is loaded against three symmetrically positioned rollers, the MPT-3000 accelerates material stress accumulation, allowing users to reach millions of cycles in a fraction of the time required by traditional systems.
As the authorized distributor for Rtec Instruments in Singapore, LMS Technologies Pte Ltd brings this industry-leading solution to local automotive R&D departments, industrial laboratories, petrochemical refiners, and academic institutions. We ensure your success with specialized regional technical service, standards-compliant calibration, and expert application support.

Key Functions & Core Benefits
- Accelerated High-Cycle Fatigue Testing: The triple-disk design subjects the central specimen to three stress cycles per revolution. This geometry drastically reduces testing time, making it the ultimate tool for rapid, high-cycle accelerated life testing of materials.
- High-Torque Independent Speed Control: Powered by high-torque servo motors (up to 60 Nm), the MPT-3000 provides smooth, precise motion control. It supports highly adjustable Sliding-to-Roll Ratios (SRR) ranging from -200% to +200%, accommodating the most complex testing protocols.
- Advanced Multi-Sensor Diagnostics: Integrate highly sensitive in-line tracking tools, including Acoustic Emission (AE) for capturing micro-crack propagation and subsurface pitting onset, and Electrical Resistance mapping to evaluate lubricant film thickness and breakdown thresholds.
- Versatile Environmental Simulation: Replicate severe industrial and automotive operating climates with integrated heating and cooling modules. The system supports both dry contact testing and full fluid immersion across a temperature range of -35°C to 150°C.
Targeted Industrial Applications in Singapore
Our MPT-3000 configuration is tailored to support the evolving needs of Singapore’s high-tech and heavy-duty industries:
- Electric Vehicle (EV) Powertrains: Screen specialized low-viscosity e-fluids, e-axle lubricants, and advanced materials designed to resist high-speed, rolling-sliding contact in compact electric drive systems.
- Industrial & Automotive Gear Oils: Evaluate anti-pitting performance, surface fatigue limits, and the efficiency of Extreme Pressure (EP) additives in transmission fluids, hydraulic oils, and high-load gear lubricants.
- Railway & Rolling Mills: Model heavily loaded contact mechanics to study wheel-rail friction variations, corrugation triggers, and the durability of steel surface treatments under cyclic stress fatigue.
