The Wide-Range Load Friction and Wear Testing Machine is a versatile tribological test system designed to evaluate friction and wear behavior under an exceptionally wide load and speed range. By combining low-load high-sensitivity testing with stable high-load capability, the system enables comprehensive assessment of materials, lubricants, and surface treatments under conditions close to real operating environments.
Standards
The system supports test methods commonly referenced in international tribology standards, including:
ASTM G99 (Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus)
ASTM G133 (Linearly Reciprocating Ball-on-Flat Sliding Wear)
ISO 7148 (Plain Bearings — Testing of Friction and Wear)
JIS K 7218 (Testing Methods for Plastic Tribological Properties)
Parameters
