CQ2WB Series Compact Cylinder | Double Rod Double Acting Air Cylinder

CQ2WB Series Compact Cylinder | Double Rod Double Acting Air Cylinder

Product Overview

The PRIUS CQ2WB Series is a high-performance, space-saving compact pneumatic cylinder featuring a distinctive double rod and double acting configuration. Engineered precisely for modern industrial automation, this series delivers equal force and speed in both directions while ensuring exceptional non-rotating accuracy and resistance to lateral loads.

With a comprehensive range of bore sizes from Φ12mm to Φ100mm, the CQ2WB series is the ideal interchangeability choice for footprint-constrained packaging, semiconductor, and lithium-ion battery production lines worldwide.

• Product Type: Thin-type Compact Pneumatic Cylinder

• Action Mode: Double Acting (Air Extend & Air Retract)

• Shaft Configuration: Double Rod (Dual Output Shafts)

• Bore Sizes (mm): 12, 16, 20, 25, 32, 40, 50, 63, 80, 100

Technical Specifications & Standard Stroke Matrix

Core Product Advantages

1. Balanced Linear Force & Equalized Velocity

Unlike single-rod cylinders where the rod side has less surface area on the piston, the double rod design provides identical surface areas on both sides. This guarantees that extension force/speed and retraction force/speed remain perfectly symmetrical.

2. High Non-Rotating Accuracy & Lateral Load Resistance

The dual-rod mechanism inherently distributes bending moments evenly. This structural advantage gives the CQ2WB series excellent resistance to lateral deflection and torsional stress, making it superior for heavy side-load material handling.

3. Space-Efficient Profile

The short, thin cylinder block allows seamless integration into compact robotic grippers, medical apparatus, and machinery enclosures where standard tie-rod cylinders cannot fit.

Industrial Applications

The PRIUS CQ2WB series compact pneumatic cylinders are heavily relied on across multiple smart-manufacturing sectors:

• Lithium-ion Battery Manufacturing: High-frequency clamping and positioning modules during cell assembly and stacking.

• Semiconductor & Electronics Assembly: Precise components pick-and-place mechanisms requiring minimal kinetic vibration.

• Automated Inspection Jigs: Aligning testing probes precisely against the target parts without mechanical backlash.

• Packaging and Labeling Machinery: Multi-position sorting gates and short-stroke pushers.

Technical FAQ 

Q1: What are the differences between CQ2WB and CDQ2WB?

A: The CQ2WB is the standard version without any built-in magnetic ring on the piston, offering a slightly lighter weight. The CDQ2WB features an integrated magnet inside the piston body, allowing developers to mount external auto switches (such as magnetic proximity sensors) onto the body grooves (Z code) to monitor stroke limits.

Q2: Does this cylinder series require continuous oil lubrication?

A: No. Every PRIUS compact cylinder is pre-lubricated with a premium, wear-resistant synthetic grease during factory assembly. It can run safely and efficiently on dry, non-lubricated compressed air, significantly lowering maintenance overhead.

Q3: Are NPT or G (BSP) air port threads available for international deployment?

A: Yes. While Rc threads are machined as standard for medium-to-large bore sizes, we can provide G threads (TF) and NPT threads (TN) to comply with regional pipe fitting standards upon special engineering request.
