Airtac SAUD Double Rod Cylinder SAUD40X120
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X120 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 120mm 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 SAUD40X120
The AirTAC SAUD40X120 is a double-acting, double-rod profile cylinder. A 16 mm rod protrudes from both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields equal push and pull force of 528 N each way at 0.5 MPa. The unit is notably shorter than an ISO 15552 cylinder of the same bore.
This model features a 1/4" port, M12x1.25 rod threads, and adjustable 21 mm cushions at each end. Because this SKU lacks the -S suffix, it cannot accept magnetic sensors. For sizing, the safe working load is roughly 317 N, allowing a vertical lift of about 27 kg with a 2:1 margin. A Viton H seal option raises the operating ceiling to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X120 Is Used
Synchronized Gripper Jaws
Drives opposing gripper fingers simultaneously from a single body, ensuring perfectly matched closing pressure without external linkages.
Twin-Spindle Pickup
Carries two parallel pickup tools at opposite rod ends to load and unload parts in alternating sequence, cutting cycle time.
Balanced Vertical Lift
Lifts small platens vertically with equal force on the upstroke and downstroke, preventing sagging drift often seen in single-rod units.
Is the Airtac SAUD Double Rod Cylinder SAUD40X120 the Right Cylinder?
Choose this 40 mm bore delivering 528 N equal force when your mechanism requires anti-rotation guidance or twin tooling driven from one piston. If you need less thrust, the 32 mm bore provides 345 N both ways; for more power, the 50 mm bore offers 825 N. Mounting is limited to Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Since this is a non-magnetized SKU, you cannot mount position switches. For any stroke at or above 300 mm, always use external guide rails to prevent side-load binding.
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 SAUD40X120 FAQ
The force is equal in both directions because both faces have a 16 mm rod. It outputs 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 both chambers.
No, a plain double-rod cylinder drifts if air pressure drops or the valve centers. The adjustable 21 mm cushion only decelerates the piston near the end of the 120 mm stroke. Use an external rod lock or pilot-operated check valve for secure load holding.
