Electro-Hydraulic Servo Four-Ball Tester
Evaluate lubricant load-carrying capacity and anti-wear performance under high point-contact pressure using sliding four-ball contact.
FOUR-BALL TESTERS
Capabilities
- Electro-hydraulic servo automatic loading.
- Measures friction force and calculates the coefficient of friction.
- Supports non-seizure load, weld load and long-duration wear evaluation.
- Records temperature, friction force and friction coefficient curves; supports MRF-M wear-scar measurement.
