Bearing Application: Tramways Holding Graz Linien, beside other responsibilities, does the maintenance for the tramways. The main task was to find a bearing material that enables smooth, maintenance-free, long-lasting operation, and reduces noise emission to zero. In GGB, we found a partner who was able to provide products to meet the optimal criteria. GGB’s GAR-MAX® cylindrical bearings and HPF® flat sliding segments passed field tests convincingly with a minimum of friction and wear, noise-free operation and corrosion-free combination with the stainless steel counterpart. Both are maintenance-free and have been set as standard materials to be stocked and used henceforth for pin joint restorations. - A. Schalk, Technician Planning Dept.
