The Twin Rod Pneumatic Cylinder is a high-precision, dual-rod linear actuator designed to deliver non-rotating, stable, and torque-resistant motion in a compact form. Featuring two parallel piston rods connected to a single piston, this type of cylinder ensures excellent anti-rotation performance, making it ideal for operations where guided, accurate, and vibration-free actuation is critical.

Engineered for durability and alignment, twin rod cylinders are widely used in pick-and-place systems, packaging equipment, assembly lines, fixture positioning, and robotic tooling, where loads must be guided or maintained in a fixed orientation. The two rods move simultaneously and are supported by internal or external guide bushings, significantly increasing load bearing capacity and lateral stability.

Constructed using anodized aluminum bodies, hardened and polished stainless-steel rods, and high-performance seals, these cylinders are built for long service life and minimal maintenance. With optional magnetic pistons, adjustable stroke lengths, and multiple mounting configurations, twin rod cylinders offer unmatched precision and flexibility.
