Airtac SAUD Double Rod Cylinder SAUD32X240
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X240 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 240mm 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 SAUD32X240
The AirTAC SAUD32X240 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 exactly 345 N of thrust and pull at 0.5 MPa. The extruded aluminium barrel keeps the body shorter than a conventional cylinder of the same 32 mm bore. It uses a 1/8 inch port and M10x1.25 rod threads.
With 345 N available, the computed safe working load is roughly 207 N, translating to a vertical lift capacity of about 18 kg with a 2:1 safety margin. The 21 mm adjustable air cushions at each end manage end-of-stroke deceleration. Note this specific SKU lacks a magnet, so it cannot host CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD32X240 Is Used
Twin Tool Transfer
Drives two synchronized pickers from one piston, utilizing the equal 345 N force on both strokes for balanced part shuttling.
Anti-Rotation Lift
The dual rods prevent twist during vertical ascent, keeping a 240 mm travel path perfectly straight without external guides.
Cam Trip Mechanism
Uses the protruding back rod to mechanically trip a limit switch or operate a secondary mechanical latch in tight spaces.
Is the Airtac SAUD Double Rod Cylinder SAUD32X240 the Right Cylinder?
Choose this 32 mm bore when you need equal 345 N force in both directions. If you need less force, step down is not an option here as 32 mm is the smallest, but stepping up to the 40 mm bore provides 528 N both ways. Select a double-rod design for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA, or LB types matching the AirTAC SC series. Because the 240 mm stroke is under the 300 mm side-load threshold, standard support is acceptable. Remember this non-magnetic unit cannot accept 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 SAUD32X240 FAQ
Because the 12 mm rod exits both ends, the force is equal in both directions: 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 21 mm cushions only decelerate the piston near the end caps; they do not lock the load. For vertical load holding on air loss, you must add an external rod lock or a pilot-operated check valve.
