Technical Review: AirTAC SDA25X120B Ultra-Thin Cylinder - Selection Guide & Specs
Share
Overview: Solving Space-Constrained Automation Challenges
In modern industrial automation, space optimization is critical for efficient machine design. The AirTAC SDA25X120B Ultra-Thin Cylinder addresses the common challenge of fitting reliable pneumatic actuation into tight spaces where traditional Pneumatic Cylinders simply won't fit. This double-acting, external thread cylinder provides full pneumatic functionality in a compact profile, making it ideal for applications in electronics assembly, packaging machinery, medical equipment, and automated production lines where every millimeter counts.
Technical Specifications Analysis
The SDA25X120B represents AirTAC's engineering excellence in compact pneumatic solutions. Here's a detailed breakdown of its technical capabilities:
| Specification | Value | Description |
|---|---|---|
| Bore Size | 25 mm | Standard metric bore diameter for balanced force output |
| Stroke Length | 120 mm | Extended stroke capability for versatile applications |
| Cylinder Type | Double Acting | Provides power in both extension and retraction directions |
| Mounting Style | External Thread | M10x1.25 external threads for secure mounting |
| Profile Height | Ultra-Thin (approx. 20mm) | Compact design for space-constrained installations |
| Operating Pressure | 0.1-1.0 MPa | Standard industrial pneumatic pressure range |
| Maximum Pressure | 1.5 MPa | Peak pressure capability for demanding applications |
| Temperature Range | -10°C to 80°C | Suitable for most industrial environments |
| Port Size | M5 | Standard metric port for Pneumatic Fittings |
| Rod Diameter | 10 mm | Sturdy piston rod for reliable operation |
| Material | Aluminum Body, Steel Rod | Lightweight construction with durable components |
| Magnet Ring | No | Standard version without position sensing |
The ultra-thin profile of this cylinder makes it particularly valuable in applications where multiple actuators need to be mounted in close proximity or where overall machine dimensions must be minimized. The double-acting design ensures positive control in both directions, unlike single-acting cylinders that rely on springs for return motion.
Buying Considerations: Selection Guide
When selecting the AirTAC SDA25X120B or similar ultra-thin cylinders, consider these critical factors:
- Space Requirements: Measure your available mounting space carefully. The "ultra-thin" designation refers to the cylinder's reduced profile height compared to standard cylinders. Verify that the 25mm bore and 120mm stroke meet your application's force and travel requirements.
- Force Calculations: Calculate required force using F = P × A (Force = Pressure × Area). At 6 bar (0.6 MPa), this cylinder generates approximately 295N of force. Ensure this meets your application needs, especially for pushing, clamping, or lifting operations.
- Mounting Configuration: The external thread design (M10x1.25) requires compatible mounting brackets or tapped holes. Consider whether front flange, rear flange, or clevis mounting would better suit your application. Review our selection of Cylinder Mounting Brackets for compatible accessories.
- Speed Control: Ultra-thin cylinders may require flow control valves to regulate extension and retraction speeds. The compact design can result in faster movement if not properly controlled.
- Environmental Factors: While rated for -10°C to 80°C, consider additional protection if operating in harsh environments with dust, moisture, or chemicals. The aluminum construction provides good corrosion resistance but may require additional sealing in aggressive environments.
- Position Sensing Needs: The standard SDA25X120B does not include a magnet ring for position sensing. If you require position feedback, consider models with built-in sensors or explore external sensing solutions from our Pneumatic Sensors category.
- Compatibility with System Components: Ensure compatibility with your existing Pneumatic Valves, filters, regulators, and lubricators. The M5 port size is standard but verify your fitting requirements.
Frequently Asked Questions
Q1: What are the main advantages of ultra-thin cylinders over standard cylinders?
Ultra-thin cylinders like the AirTAC SDA25X120B offer significantly reduced profile height (typically 40-50% thinner than standard cylinders) while maintaining the same bore and stroke capabilities. This allows for more compact machine designs, higher density mounting of multiple actuators, and installation in space-constrained applications where traditional cylinders won't fit. They're particularly valuable in electronics manufacturing, medical equipment, and automated assembly lines.
Q2: Can the SDA25X120B be used in vertical applications?
Yes, the double-acting design makes this cylinder suitable for vertical applications. However, when used vertically, consider the load weight and potential for "dropping" if air pressure is lost. For critical vertical applications, consider adding mechanical brakes or using pilot-operated check valves to prevent uncontrolled movement. The external thread mounting provides secure attachment points for vertical installations.
Q3: What maintenance is required for ultra-thin pneumatic cylinders?
Maintenance requirements are similar to standard cylinders but with some considerations for the compact design: regular lubrication through the air supply (using FRL units), periodic inspection of rod seals for wear, and checking mounting hardware for tightness. The reduced size means internal components are more compact, so proper filtration (5 micron or better) is essential to prevent contamination damage.
