Aluminum alloy compact pneumatic cylinder CQ2 type with magnetic piston for automation equipment

What Is a CQ2 Compact Cylinder?

A CQ2 compact pneumatic cylinder is a reduced-length air actuator designed to deliver linear motion where installation space is limited. Compared with standard ISO cylinders, the CQ2 design:

Has a significantly shorter overall length
Maintains comparable output force
Reduces equipment footprint
Improves modular system integration

This makes it ideal for modern automation lines where machine density is increasing.

Key Advantages of CHDAC CQ2 Compact Cylinders

Space-Saving Structure

The shortened body design allows installation in:

Pick-and-place modules
Electronic assembly machines
Packaging and labeling systems
Semiconductor auxiliary mechanisms
Robotic positioning units

When equipment space is tight, compact cylinders become the preferred solution.

High-Strength Aluminum Alloy Body

Lightweight yet rigid structure
Corrosion-resistant surface treatment
Excellent heat dissipation
Reduced machine load weight

Ideal for high-speed automation environments.

Stable Output Force

Theoretical output force at 0.6 MPa:

Bore Size	Approx. Output Force
20 mm	≈ 188 N
32 mm	≈ 482 N
40 mm	≈ 754 N
63 mm	≈ 1,870 N

Formula:
Force (N) ≈ Pressure (MPa) × Piston Area (mm²)

Our engineering team can assist with force calculation to ensure correct selection.

Long Service Life & Smooth Operation

Hard chrome-plated piston rod (45# steel equivalent)
Precision sealing system for air tightness
Self-lubricating bearing design
Suitable for lubrication-free operation

Even in high-cycle production lines, the cylinder maintains stable repeatability and low noise levels.

Magnetic Piston for Automation Control

Optional built-in magnet allows installation of:

Reed switches
Solid-state sensors
PLC position monitoring systems

This supports automated motion feedback and production cycle control.

Selection Guide – How to Choose the Right CQ2 Compact Cylinder

Confirm Required Force

Calculate load and apply safety factor (usually 1.3–1.5).

Select Appropriate Bore Size

Larger bore = higher force.

Choose Stroke Length

Avoid excessive stroke to reduce size and air consumption.

Decide Acting Type

Double Acting → More precise control
Single Acting → Lower air usage

Determine Sensor Requirement

If automation feedback is needed, select magnetic piston type.

If you are unsure, send us your load and stroke requirement — we will recommend the correct model.

FAQ

What is the difference between single acting and double acting compact cylinders?

Single acting cylinders use compressed air in one direction and spring return.
Double acting cylinders use compressed air for both extension and retraction, providing better speed control and stability.

Can this CQ2 cylinder replace original CQ2 models?

Yes, our CQ2 type cylinders are dimensionally interchangeable with standard CQ2 series models. We recommend confirming critical mounting dimensions before replacement.

Do CQ2 compact cylinders require lubrication?

They are designed for lubrication-free operation under clean, filtered air. If lubricated air is used, lubrication must remain continuous.

What is the typical service life?

Under normal industrial conditions with clean air supply, compact cylinders can operate for millions of cycles. Actual life depends on load, pressure, and environment.
