Lever-Loaded Four-Ball Tester
Assess lubricant load-carrying capacity and long-duration anti-wear performance with a deadweight-and-lever loading system.
FOUR-BALL TESTERS
Capabilities
- Evaluates non-seizure load, weld load and load-wear performance.
- Measures friction force and calculates friction coefficient.
- Computer monitoring of temperature and friction curves.
- Special fixtures can extend the system to end-face and material wear tests.
