Key Performance Advantages

Multi‑Standard CompatibilityFully compliant with GB/T 3142, SH/T 0189, SH/T 0202 and SH/T 0204, enabling complete evaluation of load‑carrying capacity, anti‑wear performance and extreme‑pressure properties of lubricating oils and greases.
Precision Mechanical StructureThe tester features a rigid frame, high‑precision rotating spindle, lever loading system, temperature control and display unit, and wear‑scar measuring system. All components are precisely matched to ensure stable performance and easy operation.
High‑Precision Test PerformanceThe high‑accuracy spindle effectively reduces measurement deviation. The equipped dedicated microscope allows clear and rapid observation of wear scars, ensuring high repeatability and reliability of test results.
Comprehensive Performance EvaluationUsing four standard 12.7 mm steel balls under point‑contact sliding friction, the instrument measures P₈ (oil film strength), P_D (weld load), Z_MZ (comprehensive wear value) and long‑term wear. It also supports evaluation of temperature effects on lubrication performance and thermal characteristics.

Typical Applications

Lubricant & grease manufacturers for quality control and R&D of anti‑wear & extreme‑pressure additives
Automotive and industrial machinery OEMs for lubricant performance verification
Third‑party testing laboratories and commodity inspection authorities
Research institutes engaged in tribology and lubrication technology research
