Reciprocating Friction and Wear Tester

The machine operates by applying a specified normal contact load while the specimen performs a linear reciprocating motion over a set stroke length. It features a stepless speed adjustment system, allowing testing at low or high speeds. The tester evaluates the friction and wear performance of lubricants, metals, plastics, coatings, rubber, ceramics, and other materials. Typical test configurations include pin-on-disk, ball-on-disk, and similar forms.

The tester consists of the main frame, axial loading module, linear reciprocating module, specimen fixtures, heating device, and measurement system. The loading system employs precision ball screws, linear ball bearings, and a loading shaft, resulting in low friction and minimal influence on test force accuracy. A load sensor is installed between the loading shaft and piston, providing high sensitivity and accurate test force measurement. The test force is precisely controlled by a high-accuracy servo motor, offering fast response, high control precision, and minimal impact on test results.

The measurement and control software is Windows-based and supports XP, Win7. Win8. and Win10 systems. Test force application is controlled via a servo system, ensuring stable and reliable force. All test parameters—including spindle speed, rotation count, applied force, friction force, friction component temperature, and test duration—are computer-controlled. Real-time data acquisition enables plotting of friction force vs. time, friction coefficient vs. time, and temperature vs. time curves.
