Grafimec evolved many lines of product to the mechanical industry, with applications of the heavy machinery and even compounds to hydraulic sector; meeting also the necessities of electromechanical industry.
Thus, the sliding systems by Grafimec can be used in many applications in mechanical parties with rotatory or translational movement.
The limitation of the GU range is its resistance to corrosion due to the carbon steel substrate. This weakness is addressed by GU-B range where carbon steel is replaced by CuSn8 bronze. The construction follows the same steps as GU: Cu skin - electrolyte, sintered bronze and self-lubricating skin on lead-free additivated PTFE.
Smooth and flanged bushings, thrust washers, plates and special parts are available in several dimensions.
