In this study, buckling analyzes of auxiliary cylinders and ram cylinder which are the most important parts of industrial 300 tons H-type hydraulic press are realized for safety factor calculations. For this purpose; linear buckling analyzes of cylinder rods of auxiliary cylinder and ram cylinder are performed by using finite element method. As a result; maximum Von Misses stress locations, safety factors of static analysis, maximum deformation results and safety factors of buckling of cylinders are determined via ANSYS Workbench software.
