Airtac SAUD Double Rod Cylinder SAUD40X500
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X500 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 500mm stroke, 1/4" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUD Double Rod Cylinder SAUD40X500
The AirTAC SAUD40X500 is a double-acting, double-rod profile cylinder with a 40mm bore and 500mm stroke. A rod exits both ends, meaning push and pull forces are identical at 528N each way at 0.5MPa. The extruded aluminium body is shorter than a standard ISO 15552 unit of the same bore. It uses a 1/4" port and M12x1.25 rod thread.
This configuration yields a safe working load of roughly 317N, or a vertical lift capacity of about 27kg with a 2:1 safety margin. The twin-rod layout prevents piston twist, ideal for driving two tools at once. Without the -S magnet suffix, this SKU cannot accept CMSG or DMSG sensors. A plain cylinder drifts on air loss; the 21mm cushions only decelerate near stroke end, so fit an external rod lock to hold loads.

Where the Airtac SAUD Double Rod Cylinder SAUD40X500 Is Used
Synchronized Transfer
Drives dual pick-and-place fingers simultaneously from both rod ends, ensuring perfectly parallel material transfer without twist.
Twin-Tool Machining
Powers two opposing stamping or forming heads at once, keeping cutting forces balanced and maintaining precise alignment.
Balanced Vertical Lift
Raises and lowers light jigs with equal push and pull thrust, preventing gravity-induced sag on the downward return stroke.
Is the Airtac SAUD Double Rod Cylinder SAUD40X500 the Right Cylinder?
Choose this 40mm bore delivering 528N equal force if you need anti-rotation guidance or twin tooling over a 500mm travel. For lower force, the 32mm bore provides 345N; for higher force, the 50mm bore gives 825N. Mounting uses SC-series FA flange or LB foot brackets. At 500mm stroke, add external guides to prevent rod bending under side loads. Because this SKU lacks the -S magnet, it cannot host position sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUD Double Rod Cylinder SAUD40X500 FAQ
Because the rod exits both ends, force is equal in both directions: 528N at 0.5MPa, 739N at 0.7MPa, and 950N at 0.9MPa. It uses a 1/4" port.
No, this specific SKU lacks the -S magnet option, so it cannot host CMSG or DMSG switches. You would need the -S variant for rear-rod cam sensing.
