Abstract
A pin-on-disk type wear testing device which has a non-contact type displacement gauge that moves integrally with the pin type testpiece sliding against the disk type testpiece, so that the said pin-on-disk type wear testing device of the present invention can accurately measure the displacement of the pin type testpiece with respect to the disk type testpiece without being affected by the waving motion of the disk type testpiece, the thermal expansion of the whole device, and other factors, thus making it possible to accurately measure the amount of wear of the pin type testpiece.
