Block-on-Ring Friction and Wear Testing Machine (Metal Testing)
Block-on-ring test machine for evaluating the friction and wear characteristics of metals, plastics, coatings and lubricants
Standards
Compliant with ASTM D2782, ASTM D2509, IP 240, and IP 326 standards for friction and wear testing.
Applications
Widely used in industries such as petrochemicals, mechanical engineering, energy, transportation, metallurgy, aerospace, automotive manufacturing, and lubrication engineering. It is also a valuable tool in academic and research institutions for advanced studies on material performance and lubricant evaluation.
The block-on-ring testing machine is designed to evaluate the friction and wear behavior of metals, plastics, coatings, and lubricants under controlled conditions. By using a rotating standard ring and a fixed rectangular block, this friction and wear machine simulates real-world friction scenarios to assess material performance. During testing, the friction and wear testing system measures the width of wear scars on the block under varying loads, while also tracking the friction forces and friction coefficient between the test materials. It can operate under oil-immersed conditions to evaluate lubricant performance and is especially useful for studying the wear resistance of high-performance automotive gear oils.
