Airtac SAUD Double Rod Cylinder SAUD40X475
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X475 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 475mm 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 SAUD40X475
The AirTAC SAUD40X475 is a double-acting, double-rod profile cylinder with a 40 mm bore and 475 mm stroke. A 16 mm rod exits both ends, meaning both faces use the rod-side piston area. This yields exactly 528 N of output force at 0.5 MPa in both directions. The extruded hard-anodized aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" port, M12x1.25 rod threads, and 21 mm adjustable air cushions at each end.
Because the rear rod protrudes, it can drive twin tooling or carry a switch cam for external tracking. Based on the 528 N figure, the safe working load is roughly 317 N, translating to a vertical lift capacity of about 27 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet (-S), so internal CMSG or DMSG sensors cannot be fitted. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUD Double Rod Cylinder SAUD40X475 Is Used
Twin-Tool Transfer
Drives two synchronized gripping fingers from opposite rod ends to transfer small parts evenly between conveyor stations.
Anti-Rotation Lift
Lifts a 27 kg vertical payload using the equal both-ways force, relying on the dual rods to prevent twist without external guides.
Cam-Actuated Cutting
Uses the extended back rod to trip an external mechanical limit switch, timing a blade cut precisely at the 475 mm stroke end.
Is the Airtac SAUD Double Rod Cylinder SAUD40X475 the Right Cylinder?
Choose this 40 mm bore when you need 528 N of equal push and pull force at 0.5 MPa. If your application requires less force, the neighbouring 32 mm bore provides 345 N both ways; if you need more, the 50 mm bore offers 825 N both ways. A double-rod design is the right call for anti-rotation guidance, twin-tool driving, or rear-cam tracking. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 475 mm stroke is relatively long, you should use external guide rails to prevent rod bending and manage side loads. This non-magnet SKU cannot accept internal 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 SAUD40X475 FAQ
The force is equal in both directions because the 16 mm rod exits both ends. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4" port supplies air to drive these loads at 30-800 mm/s.
No, a plain double-rod cylinder drifts without live air; the 21 mm cushions only decelerate near stroke end. For a held vertical load, add an external rod lock or pilot-operated check valve. Also, this non-S SKU lacks a magnet for internal sensors.
