Airtac SAUD Double Rod Cylinder SAUD32X55S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X55S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 55mm 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 SAUD32X55S
The AirTAC SAUD32X55S is a double-acting, double-rod profile cylinder. A 12 mm rod protrudes from both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields exactly 345 N of thrust and pull at 0.5 MPa, ensuring perfectly symmetrical output. The 1/8 inch port feeds the chambers, while the 55 mm stroke operates smoothly at 30-800 mm/s.
Because the profile body is shorter than a standard ISO 15552 unit of the same bore, it saves valuable machine space. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. For sizing, the safe working load is roughly 207 N, and it can vertically lift around 18 kg with a 2:1 safety margin. Note that the end cushions only decelerate the load; an external rod lock is required to hold position on air loss.

Where the Airtac SAUD Double Rod Cylinder SAUD32X55S Is Used
Synchronized Transfer
Drives two pick-and-place fingers simultaneously from one piston, keeping parallel tooling perfectly aligned without twisting.
Back-Rod Sensing
Uses the rear protruding rod to trip a CMSG or DMSG switch cam, freeing the front end entirely for the working tool.
Anti-Rotation Jaws
Grips small electronic components with equal 345 N force in both directions, preventing part rotation during clamping.
Is the Airtac SAUD Double Rod Cylinder SAUD32X55S the Right Cylinder?
Choose this 32 mm bore when you need equal push and pull force in a compact footprint. If you need more power, stepping up to the 40 mm bore raises the equal force to 528 N at 0.5 MPa. If you need less, AirTAC does not offer a smaller standard SAUD bore. The double-rod architecture is the right call for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet allows solid state or reed sensing. At a 55 mm stroke, side loads are minimal, but always use external guides for strokes over 300 mm.
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 SAUD32X55S FAQ
The force is equal in both directions because of the double-rod design. It provides 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.
The twin-rod layout prevents piston rotation, allows a sensor cam to ride on the back rod, and drives two tools at once. The extruded profile body is also shorter than an ISO 15552 cylinder of the same bore.
