Friction Tests
These test benches are designed to measure friction losses, which are then converted into coefficients. They usually have to be adapted to the required test situation.

Pin-on Disc Test
The Pin-on Disc test bench is one of the most widely used tribological test. The coefficient of friction µ or f for two materials in a specific system can be determined at room temperature.
Standard: ASTM G99, ASTM G133, DIN50324
Load (max): 60N normal load, friction force 20 N
Torque: 450 mNm
Speed (max): 0.37 m/sec
Disc rotation speed: 0-50 rpm
Results: Friction coeffizient, damage pattern
Options: Oscillating movements
Note: The given parameters are according to ASTM Standard. Others on request.
Principle
The block on ring experiment is intended to study the behaviour of two materials under certain conditions. It allows performance comparisons of system pairings of materials, lubricants and high temperatures as they occur in many real systems.
Sliding Friction Wear Test
This test bench was originally built for friction testing at high temperatures and under controlled aggressive atmospheres. Specifically for large marine diesel engines. Later, complex measurement and control technology was installed for other applications.
Standard: ASTM G77
Load: 1-150 N
Sample moving speed: Fixed, turning
Sample moving distance: 0.24 m per cycle/rotation
Ring rotation speed: 1500 rpm
Temperature: Max. 750°C
Atmosphere: According to specification
Results: Weight loss, friction coefficient
Note: The given parameters are according to ASTM Standard. Others on request.
