Airtac SAUD Double Rod Cylinder SAUD40X700
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X700 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 700mm 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 SAUD40X700
The AirTAC SAUD40X700 is a double-acting, double-rod profile cylinder with a 40 mm bore and 700 mm stroke. A rod protrudes from both ends, meaning both faces use the rod-side area. This yields equal force in both directions, delivering 528 N each way at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" port, an M12x1.25 rod thread, and adjustable 21 mm air cushions at both ends.
Because this SKU lacks the -S magnet suffix, it cannot accept magnetic switches. For demanding thermal environments, a Viton H seal option extends the operating range up to 150 C. Based on the 528 N output, the safe working load is roughly 317 N, which translates to a vertical lift capacity of about 27 kg with a 2:1 safety margin. Note that standard air cushions only decelerate the piston near stroke end; they do not hold the load if air pressure drops.

Where the Airtac SAUD Double Rod Cylinder SAUD40X700 Is Used
Synchronized Transfer
Drives two parallel conveyor pickup heads at once, using the twin rods to keep the tooling perfectly synchronized without twisting.
Dual-End Machining
Mounts a machining spindle on the front rod and a counterweight or switch cam on the back rod for balanced, compact automated milling.
Vertical Lift Gate
Raises and lowers a light 27 kg material gate with equal push and pull force, maintaining smooth operation in both directions.
Is the Airtac SAUD Double Rod Cylinder SAUD40X700 the Right Cylinder?
Choose this 40 mm bore if your application requires 528 N of equal bidirectional force at 0.5 MPa. Sizing up to the 50 mm bore provides 825 N, while stepping down to the 32 mm bore offers 345 N. The double-rod design is ideal when you need anti-rotation guidance, twin tooling on one piston, or a back-end cam. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 700 mm stroke is long, you must use external guide rails to prevent rod bending and side-load damage. As a non-magnetized SKU, it cannot host 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 SAUD40X700 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 unit features a 1/4" port and operates at speeds between 30 and 800 mm/s.
No. This SKU lacks the -S magnet, so it cannot accept CMSG or DMSG sensors. Additionally, the air cushions only decelerate the piston; they do not lock. For vertical load holding on air loss, you must install an external rod lock or pilot-operated check valve.
