Airtac SAUD Double Rod Cylinder SAUD40X220
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X220 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 220mm 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 SAUD40X220
The AirTAC SAUD40X220 is a double-acting double-rod profile cylinder with a 40mm bore and 220mm stroke. A 16mm rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields an equal output force of 528 N each way at 0.5 MPa. The 1/4" port drives the unit at 30-800 mm/s.
This extruded aluminium body is shorter than an ISO 15552 cylinder of the same bore. The twin rods prevent rotation and can drive dual tools. Based on the 528 N figure, your safe working load is roughly 317 N, equating to a 27 kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot take a sensor switch.

Where the Airtac SAUD Double Rod Cylinder SAUD40X220 Is Used
Twin-Tool Transfer
Drives two identical pickers simultaneously from both rod ends to move parts evenly across a conveyor.
Anti-Rotation Clamp
Holds a workpiece securely during machining using the dual rods to prevent mechanical twist.
Balanced Lift Station
Raises and lowers a 27 kg payload vertically with equal push and pull force for stable positioning.
Is the Airtac SAUD Double Rod Cylinder SAUD40X220 the Right Cylinder?
Choose this 40mm bore (528 N both ways at 0.5 MPa) if you need synchronized motion or anti-twist guidance. Step down to the 32mm bore for 345 N, or up to the 50mm bore for 825 N. The 220mm stroke is under the 1200mm max standard limit, but at this length you should use external guide rails to absorb side loads. Mounting is limited to Basic, FA, and LB brackets compatible with the AirTAC SC series. Because this SKU lacks the -S magnet option, it cannot host CMSG or DMSG switches.
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 SAUD40X220 FAQ
The double-rod design provides equal force in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It uses a 1/4" port and never quotes a larger single-rod push value.
No. The air cushions only decelerate the piston near the stroke ends; they do not act as a brake. For load holding on air loss, you must fit an external rod lock or pilot-operated check valve.
