Overview
The SMC CDNGBN20-100-D-H7A2L is a compact pneumatic cylinder from SMC’s renowned CNG series, featuring an integrated lock mechanism for load-holding capability. This double-acting, single-rod design operates at 1.0 MPa (10 bar) pressure and delivers reliable performance in automation and industrial applications. The unit is in used condition but fully functional, making it an economical choice for system upgrades and replacements.
Key Features
- Double-acting, single-rod cylinder configuration for efficient bidirectional motion
- Integrated lock mechanism for secure load holding and safety
- Compact 20 mm bore design suitable for space-constrained installations
- 100 mm stroke for balanced reach and control
- Rated for 1.0 MPa (10 bar) pneumatic pressure
- Standard ports compatible with existing SMC pneumatic networks
Technical Specifications
The cylinder operates within SMC’s design standards for industrial pneumatic automation. The 20 mm bore combined with the 100 mm stroke provides controlled linear motion suitable for material handling, assembly processes, and positioning applications. The integrated lock feature ensures load stability during pressure loss or emergency situations, a critical requirement in many safety-critical installations.
Typical Applications
- Industrial automation and production line equipment
- Material handling and part positioning systems
- Assembly machinery requiring load-holding capability
- Machine tools and precision positioning equipment
- Clamping and fixture applications where safety lockout is required
Compatibility & Replacements
Compatible With
- SMC pneumatic valve systems and manifolds
- Standard ISO 4401 and SAE cavity pneumatic systems
- 15 mm (NPTF and SAE) and metric port connections
