Airtac SAUD Double Rod Cylinder SAUD40X165
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X165 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 165mm 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 SAUD40X165
The AirTAC SAUD40X165 is a double-acting, double-rod profile cylinder with a 40 mm bore and 165 mm stroke. Because a rod exits both ends, the push and pull force is identical, delivering 528 N each way at 0.5 MPa (739 N at 0.7 MPa, 950 N at 0.9 MPa). The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 1/4" port, an M12x1.25 rod thread, and adjustable air cushions at both ends.
This configuration is ideal for non-rotating guidance or driving twin tooling. The 528 N output yields a safe working load of about 317 N, translating to a vertical lift capacity of roughly 27 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD40X165 Is Used
Twin-Tool Transfer
Drives two parallel workheads simultaneously from one piston, keeping pressure perfectly balanced across both ends of the 165 mm stroke.
Anti-Rotation Lift
Uses the dual rods to prevent twist during vertical elevation, ensuring precise platen alignment without external linear bearings.
Symmetric Clamping
Applies identical 528 N clamping pressure on both the extend and retract strokes to hold delicate components evenly.
Is the Airtac SAUD Double Rod Cylinder SAUD40X165 the Right Cylinder?
Choose this 40 mm bore when you need equal 528 N force in both directions for synchronized lifting or anti-twist stability. If your application requires less force, the 32 mm bore provides 345 N both ways; for heavier loads, step up to the 50 mm bore which provides 825 N both ways at 0.5 MPa. Mounting is limited to Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. At a 165 mm stroke, side loading is minimal, but always guide the load externally to prevent binding. Because this is a non-magnet SKU, switch sensing is unavailable.
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 SAUD40X165 FAQ
The force is equal in both directions due to the double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It never produces a larger single-rod push value.
No, a plain double-rod cylinder drifts without live air, as the cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
