  • In the application, Slydway displays only a slight difference between static and dynamic friction, thus eliminating any presence of stick slip.

Figure shows the range of static friction when using different oils. The values were determined on a scraped Turcite®-B sliding surface with a surface contact pressure of 35 N/cm2 and a surface roughness of the guide of Ra=0.6 µ.m. Figure shows the least differences at the transition to the hydrodynamic range. With higher surface pressures of up to 200 N/m2, the sliding behaviour changes only insignificantly. Good lubrication is of paramount importance in order to achieve a controlled level of dynamic friction.

Wear

  • Testing data from testing completed at Corporate R&D

  • Turcite B Slydway should always be well lubricated during the start-up phase. Very fine particles of the Turcite B Slydway are transferred to the mating surface during the start-up phase.

    •  This leads to the slight shading of the metallic mating surface.

    • The start-up phase is concluded with the smoothing phase.

  • After the smoothing phase, Turcite B Slydway will experience a low level of both the wear and friction, thus essentially remaining constant.
