Hollow Piston Rods

Hollow Piston Rods
Hollow Piston Rods are specially designed for hydraulic cylinders, pneumatic cylinders, and industrial equipment requiring reduced weight, internal fluid passage, or customized structural design. Compared with solid rods, hollow piston rods offer the advantage of lower weight while maintaining good mechanical strength and stable performance.

Product Details

Summary


Hollow Piston Rods are widely used in applications where both mechanical strength and weight reduction are important. The hollow structure helps reduce the overall weight of the component and can also provide space for special functional requirements in certain hydraulic or mechanical systems.

Our hollow piston rods are manufactured with strict tolerance control and can be processed with hard chrome plating, grinding, polishing, and cutting to length. With good surface finish, wear resistance, and reliable dimensional accuracy, they are suitable for OEM production and replacement applications.
