Materials Used In Guide Elements And Their Characteristics

MATERIALS USED IN GUIDE ELEMENTS AND THEIR CHARACTERISTICS

Today the cylinders are expected to work with high speed, high forces without any problems during the application. Operating temperature, sliding speed, media and the operating forces of the system are important factors in choosing the guide element to achieve these expectations. Most common non metallic guide element materials are special filled PTFE, special filled or pure Polyacetal (POM), fiber or polyester resin. Usage of the metallic guide elements reduced over the past years but still for some applications it is been used..

 

Our guide elements can be divided into three main categories. Figure 33 shows the surface contact pressure values of these. Surface contact pressure resistance of the non metallic guide element decreases when the sliding speed and temperature increases (Figure 33 and Figure 34). In this respect the height calculation of the guide element should be done according to the maximum system temperature and speed information.
