Overview
The SMC CDQ2B50-75D is a space-saving compact cylinder from SMC’s CQ2 series, engineered for dual-direction pneumatic actuation. With a 50mm bore and 75mm stroke, this double-acting cylinder delivers consistent force output in both extension and retraction. The CDQ2B variant supports through-hole mounting via optional bolts, making it suitable for tight integration in control systems where dimensional constraints are critical.
Key Features
- Double-Acting Design: Provides power in both directions for bidirectional motion control
- Compact Body: Space-efficient profile ideal for confined mounting spaces
- Single Rod Configuration: Standard piston rod design for straightforward piping and actuation
- Optional Through-Hole Mounting: Available with chromium molybdenum steel bolts (M3 x 35L) for secure, flush integration
- Versatile Port Design: Configured for standard M5 x 0.8 piping connections
Technical Specifications
- Bore Diameter: 50 mm (ø50)
