MODENGY PTFE-A20

Truck cranes telescopic booms are subjected to heavy loads, affecting the boom sharp bend, that are distributed over the special slide guideways. In the modern machines polymers are used as material for guideways. Because of high specific pressures, grease lubricating material is squeezed out of the friction zone what causes stick-slip motion of the boom as well as to corrosion arising.

MODENGY PTFE-A20 coating based on polytetrafluorethylene forms an anti-friction layer on the surface having high load-carrying capacity. This coating is applied just single onto the boom sections, it has wide service temperature range (-50 … +130 °С), and high adhesion. While operating jointly with a grease, the coating reduces friction coefficient, prevents stick-slip motion, and protects against corrosion.
