MCR Tribology Cell:
T-PTD 200

  • Tribology — Measurement of Friction, Lubrication and Wear
  • Tribology — Measurement of Friction, Lubrication and Wear
  • Based on the ball-on-three-plates measuring principle
  • Excellent temperature control from -40 °C to +200 °C
  • Sliding speed control of up to 3.3 m/s
  • Rolling bearing attachment optional

The ball-on-three-plates setup is a well-established method for measuring both lubricated as well as dry tribological systems. Different measuring geometries (plates, cylinders) are available for adaptation to specific sample needs. The heart of this setup is the T‑PTD 200 tribology cell which ensures precise alignment and therefore a homogeneous distribution of normal forces on the measured samples. To investigate lubricant performance in a bearing or to characterize the bearing itself, the T‑PTD 200 tribology cell can be equipped with a rolling bearing attachment. With this setup, different bearing types can be measured under axial loads.
