Airtac SAUD Double Rod Cylinder SAUD32X425
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X425 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 425mm stroke, 1/8" 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 SAUD32X425
The AirTAC SAUD32X425 is a double-acting, double-rod profile cylinder. A 12 mm rod exits both ends, meaning both faces use the rod-side piston area. This yields equal push and pull force of 345 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same 32 mm bore.
This specific SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG sensors. The 1/8 inch port and M10x1.25 rod thread are fixed by the bore. Based on the 345 N output, the safe working load is about 207 N, which translates to a vertical lift capacity of roughly 18 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD32X425 Is Used
Twin-Tool Transfer
Drives two opposing pick-off fingers simultaneously, ensuring perfectly synchronized part ejection on a conveyor line.
Balanced Vertical Lift
Raises and lowers an 18 kg jig with identical force both ways, preventing gravitational drift during downward travel.
Anti-Rotation Clamp
Holds a workpiece flat without twist, using the dual rods to resist torsional stress during machining.
Is the Airtac SAUD Double Rod Cylinder SAUD32X425 the Right Cylinder?
When sizing this 32 mm bore, step down or up using the equal both-ways force figures: a smaller bore is unavailable, while the next size up is the 40 mm bore delivering 528 N at 0.5 MPa. Choose this double-rod configuration when you need anti-rotation guidance, twin tooling, or a back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot options, matching the AirTAC SC series. Because the 425 mm stroke exceeds 300 mm, fit external guides to prevent rod bending and absorb side loads. Note that this non-magnet version 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 SAUD32X425 FAQ
The force is equal in both directions because rods exit both ends. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The 1/8 inch port supplies air to both chambers.
No. The air cushions only decelerate the piston near stroke end; they do not act as a brake. The piston will drift on air loss. Use an external rod lock or pilot-operated check valve for secure load holding.
