E355 Hollow Piston Rod
A piston rod is a crucial structural component in hydraulic and pneumatic cylinders, acting as the connecting link between the piston and the external mechanism it powers. Piston rods are typically divided into solid and hollow types.
While solid piston rods are machined from hard chrome plated steel bars, hollow piston rods—like the E355 variant—are fabricated from high-precision seamless tubes. These hollow rods offer benefits such as reduced weight, material savings, and compatibility with telescopic cylinders.

Applications
Hollow piston rods made from E355 material are ideal for telescopic hydraulic cylinders, where weight reduction and extended stroke capability are essential. Common applications include agricultural and construction equipment, industrial machinery, lifting and material handling systems, and mobile hydraulic cylinders. The hollow structure optimizes fluid space in multi-stage cylinders while maintaining excellent compressive strength.
