The article presents an analysis and comparison of friction elements consisting of Ferodo and retinax with asbestos-rubber friction material 143-63 and 8-45-62 in the nodes and brakes of forging and pressing machines operated at the factories of the forest and woodworking industry. In Russia, widely used friction materials Ferodo and retinax in the clutches and brakes of operating machines no longer satisfy consumers in many cases due to their low strength and wear resistance, which began to limit the performance of friction units. The analysis showed that the use of friction asbestos-rubber materials of grades 143-63 and 8-45-62 in the nodes and brakes of forging and pressing machines operated at the factories of the forest and woodworking industry, will dramatically increase both the productivity of machines and their performance, and also makes it possible to significantly reduce the cost of maintenance and repair of forging and pressing equipment.
