Slide-screw (SCR) test using resin nuts was conducted together with Pin-on-disk (POD) test for the same resin materials, in order to know the relations of friction coefficient and specific wear rate of resin materials for SCR between both of tests. The results showed that the friction coefficients were almost the same (-0.27) in both of the tests, while the specific wear rate tended tobecome larger in SCR test than in POD test. The larger specific wear rate in SCR tests was ascribed to the

In practice, the specific wear rate was decreased in the SCR test using the resin nut with 18 mm contact length, which was shortened by cutting the screw thread away over 1.5 mm width at every 180 degree seen from the axial direction.
