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 GU bushings range consists of an entire system of self-lubricating bearings. As a composite structure, this range consists of a steel substrate, an electrolytic copper skin, upon which is set a layer of sintered bronze, anchoring the PTFE self-lubricating surface (lead free).
Smooth and flanged bushings, thrust washers and plates complement the offered models, which may be increased with special parts manufactured according to customer drawings and specifications. All these products are consistent with ISO 3547 (DIN 1494) Regulations.
This is an almost universal self-lubricating system range and it is used in diverse industries and applications. The ability to bear high loads, low friction coefficient, self-lubricating and excellent cost/performance make these products best sellers.
