Overview
The SMC CQ2B32-20DC is a compact double-acting pneumatic cylinder from SMC’s industry-proven CQ2 series. This 32mm bore, 20mm stroke unit combines space-saving design with reliable linear motion control across manufacturing, food processing, and general automation applications. The CQ2B32-20DC features a double clevis mounting configuration, enabling flexible pivot-point attachment in systems where angular motion is required.
Key Features
- Compact body design reduces installation space while maintaining force output
- Double clevis mounting with integral pivot brackets for simplified installation
- 32mm bore, 20mm stroke combination suitable for moderate-load linear positioning
- Standard port configuration compatible with SMC pneumatic system piping
- Built-in piston rod bushing for smooth, low-friction operation
- Optional auto-switch compatibility for position sensing and control feedback

- Food processing machinery with compact footprints
- Molding and stamping press guarding
- General-purpose linear motion in space-constrained enclosures
- Equipment requiring low-friction, smooth actuation with pivot mounting
Compatibility & Replacements
Compatible With
- Standard pneumatic circuit compressors and regulators (0–1.0 MPa operating range)
- SMC directional control valves (2/2, 3/2, 4/2, 5/2 ported configurations)
- Industry-standard flow control and pressure-relief valves
- SMC push-to-connect one-touch fittings (M5 and metric thread ports)
- Standard ISO 6432 compact cylinder mounting rails and brackets
- CQ2 series auto-switches (D-A9, M9, and equivalent models) for position feedback
Replaces / Drop-In Replacement For
The CQ2B32-20DC is a direct equivalent to other SMC CQ2B32-20D configurations without custom options. Verify exact port style and end-connection configuration (standard rod nut vs. threaded) with your system requirements before substitution. Consult SMC part number specifications if replacing from a competing manufacturer cylinder—bore and stroke must match, and mounting interface geometry must be verified.
