SRV Test Module

The Rtec Instruments SRV Test Module integrated on the MFT-5000 tribometer platform is a next-generation solution for measuring coefficient of friction, wear, and extreme pressure properties of lubricants, oils, greases, solid bonded films, and additives under controlled linear oscillatory motion.

The SRV (Schwingung Reibung Verschleiss — oscillation, friction, wear) test method is one of the most widely used lubricant evaluation methods in automotive and industrial research, determining extreme pressure properties, friction characteristics, and wear performance of gear oils, hydraulic fluids, and greases under realistic oscillating contact conditions. The Rtec MFT-5000 SRV module sets itself apart with an exceptionally wide operating range — oscillation amplitude from 5 µm to 4 mm, frequencies up to 300 or 500 Hz, downforce up to 3,000 N, and temperature control from –40°C to 800°C — all on a single platform. The frictionless electromagnetic voice coil actuator and high-resolution piezo friction sensors ensure accurate reproduction of friction force hysteresis with negligible mechanical backlash, delivering reliable and repeatable results on both short and long-duration tests. Fully compatible with all major international tribology standards including ASTM G133, G174, D5706, D5707, D6425, D7421, D7594, ISO 19291, ISO 20120, and DIN 51834 parts 1–5, the MFT-5000 SRV module supports standard qualification testing and advanced lubricant research on the same versatile platform. Combined with the MFT-5000’s patented in-line 3D optical profilometer, wear volume, surface topography, and friction data are captured automatically in real time throughout the test — without removing the sample.

What You Can Test

The MFT-5000 SRV Module evaluates the friction, wear, and lubricating performance of virtually any tribological system under high-load reciprocating motion. Characterize engine oils, gear oils, transmission fluids, hydraulic fluids, greases, fuels, and lubricant additives, while measuring extreme pressure (EP) and anti-wear (AW) performance. Test piston ring/cylinder liner contacts, bearings, gears, cams, valve train components, splines, coatings, solid lubricants, DLC coatings, ceramics, polymers, and metal alloys. The system is equally suited for fretting wear, boundary lubrication studies, lubricant screening, material qualification, quality control, and advanced tribology research under realistic ASTM, DIN, and ISO SRV testing conditions.

Primary Applications

The MFT-5000 SRV Module is designed for standardized SRV friction, wear, and lubricant testing across automotive, aerospace, energy, and industrial applications. It is ideal for engine oil, transmission fluid, gear oil, hydraulic fluid, and grease evaluation, as well as lubricant additive development, fuel lubricity studies, coating performance, bearing and gear materials, and quality control. Supporting ASTM, DIN, and ISO SRV test methods, the system enables high-load reciprocating tribology testing for R&D, product qualification, failure analysis, and advanced materials research while offering the flexibility to perform custom tribological experiments beyond conventional SRV testing.

Electrify Your SRV Testing

Go beyond conventional SRV testing with the optional Electrified SRV Module. Apply controlled AC, DC, or programmable electrical loads while simultaneously measuring friction, wear, electrical contact resistance (ECR), impedance, current, and voltage. Reproduce the operating conditions found in electric motors, e-axles, bearings, gears, rolling contacts, and power electronics to evaluate lubricant film stability, electrical pitting, tribocorrosion, coating durability, and conductive materials. Designed for the next generation of electric vehicles (EVs), aerospace, renewable energy, and industrial electrification, the MFT-5000 provides one of the industry’s most advanced platforms for electrified tribology and electrical contact testing.
