Piston rod

Piston rods and tubes Rotary and translatory moving piston rods, shafts and tubes meet the highest quality standards due to our decades-long expertise. The precisely coordinated production steps of turning, hardening, grinding, surface coating and polishing ensure a high surface quality. For the surface refinement, in addition to the hard chrome plating for low friction and durability, we use salt bath nitriding too, which meets the requirements for corrosion protection. This results in black piston rods with an extremely hard and smooth surface, which offer less surface to be affected by harmful influences. The roughness values are precisely met depending on the series and are reliably kept within the micrometer range. In addition to the classic versions, SUSPA also offers you complex geometries such as cross-bores, millings, different diameters or axial deep hole bores. Take advantage of our experience with customers and manufacturers of chassis dampers or hydraulic cylinders who exclusively purchase their piston rods from us.
