💡 Three Highlights Solving Three Pain Points
- Highlight 1: Compact Structure Saves Installation Space Pain Point: Traditional cylinders are bulky and difficult to install in space-constrained equipment. Solution: The compact design features a small footprint. With Φ20mm bore and 10mm stroke, its dimensions are only about 34×36×36mm, occupying minimal space and fitting into tight areas.
- Highlight 2: Double-Acting Single-Rod Design for Reliable Action Pain Point: Single-acting cylinders cannot automatically reset during power or air loss, posing safety risks. Solution: The double-acting single-rod design uses compressed air for bidirectional drive, ensuring reliable and flexible control, suitable for frequent reciprocating motion.
- Highlight 3: Space Saving + High Precision, Direct Load Mounting Pain Point: Complex mounting structures increase design difficulty and assembly time. Solution: The space-saving, thin, and compact design can withstand significant lateral loads. It can be directly mounted onto various jigs and specialized equipment without additional accessories.
🎯 Five Application Scenarios, Perfectly Matched
- “Clamping Hand for Automated Assembly Lines”: Automated clamping and positioning of small-to-medium workpieces like electronic components, mechanical parts, and plastic parts.
- “Sorting Pusher for Packaging Lines”: Automatic sorting, pushing, and positioning in food packaging, daily chemical products, and small-item packaging.
- “Paper Positioning Pusher for Printing”: Paper positioning, sheet separation, and conveying in printing presses and paper handling equipment.
- “Positioner for 3C Product Assembly”: Precise positioning and clamping on assembly lines for 3C products like mobile phones, tablets, and computers.
- “Push/Pull Actuator for Lab Automation”: Sample pushing/pulling, pipetting, and positioning in laboratory automation equipment.

🛠️ Installation & Usage: “Three Do’s and Three Don’ts”
- ✅ Three Do’s:
- Mount vertically to ensure piston rod aligns with load movement direction, avoiding eccentric loads.
- Install a filter-regulator and lubricator upstream of the air supply to ensure clean, stable-pressure compressed air.
- Regularly check mounting bolts/connections for looseness and piston rod seals for leaks.
- ❌ Three Don’ts:
- Do not exceed the max. operating pressure of 1.0 MPa to prevent damage.
- Do not use in high temperature (>70℃) or corrosive environments to prevent seal aging.
- Do not let the piston rod bear lateral loads; add guide mechanisms if necessary.
🔄 Selection & Replacement Guide
- Need more thrust? → Choose CQ2B25-10D (Φ25mm) or CQ2B32-10D (Φ32mm).
- Need a different stroke? → Choose CQ2B20-5 (5mm stroke) or CQ2B20-15D (15mm stroke).
- Need a model with magnetic switch? → Choose the CDQ2B20-10D series (with magnetic switch).
- Need a different mounting style? → Choose foot-mounting, trunnion-mounting, etc.
