Airtac SAUD Double Rod Cylinder SAUD40X190
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X190 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 190mm 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 SAUD40X190
The AirTAC SAUD40X190 is a double-acting, double-rod profile cylinder. A 16mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side area. Output force is equal in both directions at 528 N each way at 0.5 MPa. This profile design is notably shorter than an ISO 15552 cylinder of the same bore.
Because the rod protrudes at the rear, you can mount a sensor cam directly on it, although this specific SKU lacks a magnet and cannot take a switch. The 1/4" port feeds the chambers, while adjustable 21mm air cushions decelerate the piston at both ends. For sizing, the 528 N output yields a safe working load of roughly 317 N, or a vertical lift capacity of about 27 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD40X190 Is Used
Twin-Tool Transfer
Drives two synchronized pick-and-place grippers from opposite rod ends to move parts across a conveyor belt simultaneously.
Balanced Vertical Lift
Lifts a 27kg fixture straight up and down with equal push and pull force, preventing sagging or uneven drift on the return stroke.
Anti-Rotation Press
Applies 528N of clamping force on a machining station where the dual rods prevent the piston from twisting under offset loads.
Is the Airtac SAUD Double Rod Cylinder SAUD40X190 the Right Cylinder?
Choose this 40mm bore model delivering 528 N equal force when your mechanism requires anti-rotation guidance or twin-tool driving from both rod ends. If you need less force, step down to the 32mm bore (345 N); if you need more, step up to the 50mm bore (1154 N at 0.7 MPa). Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 190mm stroke, side loads are moderate, but always guide the load externally to prevent binding. Note this non-magnetic SKU cannot accept CMSG or DMSG 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 SAUD40X190 FAQ
The force is equal in both directions because it is a double-rod cylinder. 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 cylinder drifts without live air, and the 21mm cushions only decelerate near stroke end rather than locking. For load holding, install an external rod lock or pilot-operated check valve.
