Humphrey Products 8-D-4 Pneumatic Cylinder

Humphrey Products 8-D-4 Pneumatic Cylinder is a model-specific linear actuator that converts compressed air into straight-line motion for pneumatic systems. The 8-D-4 designation identifies the exact cylinder configuration from Humphrey Products, enabling proper fit and replacement within automation hardware. In typical industrial applications, pneumatic cylinders provide fast, repeatable actuation to position fixtures, operate clamps, or drive tooling along a fixed stroke on manufacturing lines and material handling setups. To operate, this class of cylinder requires a source of clean, dry compressed air and a control valve (such as a solenoid-operated valve) to manage extension and retraction, with performance governed by the system pressure and cycle demands. For reliable performance, a properly filtered air supply and correct mounting alignment help reduce wear and ensure smooth movement in automation environments. Because the 8-D-4 model is part of Humphrey's range of pneumatic actuation products, it is commonly employed in applications requiring quick, repeatable strokes and cleaner, simpler actuation compared with hydraulic systems.
