Precision Rotary Vacuum Tribometer is a laboratory-grade tribological testing system designed for friction, wear, and rolling contact fatigue testing under controlled vacuum, inert gas, or atmospheric environments. You use this instrument to simulate real contact conditions between materials by precisely controlling load, rotational speed, pressure, and test duration. The system integrates a sealed vacuum test chamber, servo-driven rotary spindle, pneumatic load actuation, and high-resolution torque and force measurement to support advanced tribology research and materials evaluation.
Application
You can use the Precision Rotary Vacuum Tribometer for the following applications and test configurations:
Sliding friction and wear testing of metals, coatings, ceramics, and lubricated materials
Tribological performance evaluation under vacuum or controlled gas environments
Boundary lubrication and dry contact behavior analysis
Rolling contact fatigue testing of bearing materials and surface treatments
Comparative material screening for aerospace, vacuum, and high-reliability applications
Typical supported test configurations include:
Four-ball wear test (ASTM D2266)
Thrust washer test (ASTM D3702)
Three-pin-on-disc / pin-on-disc test (ASTM G99)
Spiral orbit ball-on-disc rolling contact fatigue test (ASTM F2661)
Standards
The system supports test configurations equivalent to the following standards:
(1) ASTM D2266 – Standard Test Method for Wear Preventive Characteristics of Lubricating Grease (Four-Ball Method)
(2) ASTM D3702 – Standard Test Method for Wear Rate and Friction Coefficient of Materials in Self-Lubricated Rubbing Contact
(3) ASTM G99 – Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus
(4) ASTM F2661 – Standard Test Method for Rolling Contact Fatigue Using a Ball-on-Disk Configuration
(5) ISO 7148 – Plain bearings — Testing of tribological properties of bearing materials
