SKF PCMS2005002.50E Metric PTFE Composite Strips 200x500x2.5mm

SKF PTFE Composite Dry Sliding Strips: SKF composite dry sliding strips provide a cost-effective and space-saving solution when designing and forming flat linear guides. Both, PTFE and POM composite strips are suitable where oscillating and rotational movement can occur. SKF PTFE composite strips are self-lubricating as well as maintenance-free and provide a long service life due to low friction. Despite their compact design, these strips can accommodate heavy loads and are suitable for relatively slow rotational or oscillating movements. They also have good dimensional stability and thermal conductivity. PTFE composite strips consist of a sheet steel backing on which a 0.2 to 0.4 mm thick porous layer of tin/bronze is sintered. Furthermore, by a rolling process, the pores of the sintered layer are filled with a mixture of PTFE and molybdenum disulphide additives. This additional 5 to 30 µm thick running-in layer provides an optimum combination of the mechanical properties of the sintered tin/bronze and the good sliding and lubricating properties of the PTFE mixture.
