Airtac SAUD Double Rod Cylinder SAUD40X130
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X130 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 130mm 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 SAUD40X130
The AirTAC SAUD40X130 is a double-acting, double-rod profile cylinder with a 40 mm bore and 130 mm stroke. A 16 mm rod exits both ends, meaning both faces use the rod-side piston area. Output is equal in both directions, delivering 528 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore, with no external rods. It uses a 1/4 inch port and M12x1.25 rod threads.
Because the rear rod protrudes, you can mount a sensor cam or trip a switch directly on the back end, though this specific SKU lacks a magnet and cannot take a switch. For sizing, the safe working load is roughly 317 N (about 60 percent of the 528 N figure), yielding a vertical lift capacity of about 27 kg with a 2:1 margin. A plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac SAUD Double Rod Cylinder SAUD40X130 Is Used
Twin-Tool Transfer
Drives two opposing pickers simultaneously with identical 528 N force, keeping cycle times synchronized without separate valves.
Anti-Rotation Lift
Lifts light jigs up to 27 kg vertically; the dual rods prevent twist and droop without needing an external linear guide.
Cam Trip Stopper
Uses the protruding rear rod as a mechanical cam to trip a limit switch at mid-stroke for indexing conveyors.
Is the Airtac SAUD Double Rod Cylinder SAUD40X130 the Right Cylinder?
Choose this 40 mm bore if you need 528 N of equal push and pull force at 0.5 MPa. Stepping down to the 32 mm bore drops the equal force to 345 N, while stepping up to the 50 mm bore raises it to 825 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or rear-end sensing. Mounting is limited to Basic, FA flange, and LB foot types, matching the AirTAC SC series. At a 130 mm stroke, side loads are minimal, but always guide the load externally on longer strokes. Note that this base SKU has no magnet, so it 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 SAUD40X130 FAQ
The force is equal in both directions because rods protrude from both ends. It generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. You must use the rear protruding rod to mechanically trip an external switch, or select an SAUD40X130-S model for magnetic sensing.
