Overview
The PHD SDD24X31/2-AE-H4-M-Q1 is a guided pneumatic slide cylinder manufactured by PHD Inc, a leading supplier of pneumatic and hydraulic actuators for automation. This model features guided rod construction for linear motion stability and is commonly used in machine tool applications, material handling, and factory automation where smooth, repeatable positioning is essential. The SDD24 bore size with 3.125-inch stroke configuration provides moderate force output suitable for light-to-medium duty applications.
Key Features
- Guided rod design ensures straight, smooth linear motion without lateral deflection
- Compact footprint optimized for space-constrained machine installations
- Pneumatic operation provides cost-effective automation without electrical power requirements
- Double-ended rod configuration (-H4 designation) enables symmetrical force output
- Durable construction suitable for repetitive industrial duty cycles
- Compatible with standard pneumatic control systems and valve packages
