Lever Type Four Ball Friction Testing Machine
Lubricant tester for testing load bearing capacity of lubricant and fatigue strength of gear
Standards
ASTM D 4172, ASTM D2266-01, ASTM D2783, ASTM D2596
Applications
Commonly used in industries that rely on the performance of lubricating oils, greases, cutting fluids, and additives. From automotive to heavy machinery and industrial equipment, it helps ensure that lubricants provide effective protection under demanding conditions, reducing wear and prolonging the life of mechanical components.
Our lever-type four ball friction tester are tools used for evaluating the performance of lubricants under high-pressure conditions, specifically their load-bearing capacity and resistance to wear. By simulating extreme point contact pressure with sliding friction, the testerhelps determine how well lubricants can protect gears and other mechanical components under stress. It measures key factors such as maximum non-seizure load (PB), sintering load (PD), and the comprehensive wear value (ZMZ), offering valuable insights for lubricant formulation and product development. These tests are essential for ensuring that lubricants meet the rigorous demands of modern industrial machinery, where reliable lubrication is critical for minimizing downtime and reducing maintenance costs.
