TYPE:20 Torque Type Friction and Wear Tester

Disk-on-disk and Ball-on-disk Friction and Wear Testing

The torque converter is directly connected to the turntable on which the test piece can be mounted.
For the loading, it will be possible to select the disk for surface contact and the ball indenter for point contact.
Because the disk and the ball indenter can both be balanced using the dead weight, low loading can be used to carry out highly accurate friction and wear testing.

Utilizes a High-Speed Rotating Turntable

Because the maximum rotation is 3000rpm, high speed wear testing can be carried out.
This is most appropriate for carrying out high speed wear testing in only one direction.

Incorporates a Torque Converter

Since the torque converter is directly connected to the turntable, even minute changes in friction can be detected.

Balance Arm Structure that Supports Various Testing

As a similar balance arm mechanism is utilized to the one in the Surface Property Tester Type: 14FW, it will be possible to use various types of measurement probes, including those for surface, point and line contact.
In addition, the vertical loading can be set in 10g steps.
