Overview
The SMC CDM2U25-150Z pneumatic cylinder is a versatile double-acting, single-rod air cylinder designed for industrial machinery and automation systems. With a 25mm bore diameter and 150mm stroke length, this compact cylinder delivers consistent performance at operating pressures up to 1.0MPa. SMC CDM2U25-150Z units are built to handle precision motion control in tight mounting spaces while maintaining smooth, reliable operation across manufacturing environments.
Key Features
- Double-acting design: Extends and retracts under pneumatic pressure for bidirectional motion control
- Compact 25mm bore: Ideally suited for equipment with limited mounting space
- 150mm fixed stroke: Precise stroke length for repeatable positioning
- Rubber bumper cushioning: Reduces shock and noise at stroke ends
- Single rod configuration: Standard piston rod design for straightforward integration
- Low to medium pressure rated: Efficient operation at 1.0MPa maximum, reduces energy consumption
