Low Load Wear Tester

Tribogear with a Minimum 0.1g-10g Loading Range
This is a wear tester that allows measurement from very low loading (0.1g) that was previously difficult to measure, to a maximum loading of 10g.
A turntable with a high speed of 3000rpm and width of 80mm is utilized to allow a wide range of wear testing.
The minimum loading from 0.1g up to 10g of the very low loading wear tester is realized using a flat spring pressing method.
For the turntable, a new type of turntable is utilized which has a low vibration that will not affect the measurement when using very low loading.
This instrument makes it possible to precisely measure the wear of thin films and surface processing, for which measurement was formerly difficult.


Housing that Separates the Drive Unit and Measuring Unit

In consideration of the measurement under very low loading conditions, the drive part which will be a source of vibration is separated from the measurement unit in order to prevent as far as possible the vibration from affecting the measurement.

Because a vacuum chuck is also available for holding the sample, the balance can be maintained during rotation.

Incorporates a Displacement Meter to Easily Determine the Wear Amount

A displacement meter is incorporated for measuring the amount of wear. This makes it possible to easily understand the wear amount.

In addition, because the loading using the flat spring has a load cell attached for calibration, precise measurement will be possible.
