Airtac SAUD Double Rod Cylinder SAUD50X105S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X105S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 105mm 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 SAUD50X105S
The AirTAC SAUD50X105S is a double-acting, double-rod profile cylinder. A 20 mm rod protrudes from both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields equal push and pull force of 825 N each way at 0.5 MPa. The extruded profile is shorter than an ISO 15552 cylinder of the same 50 mm bore.
Because the rod exits the back, you can mount a sensor cam or trip a switch on the rear stroke. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. For sizing, a safe working load is roughly 495 N (60% of the 825 N figure), translating to a vertical lift capacity of about 42 kg with a 2:1 safety margin. The 1/4 inch port and M16x1.5 rod thread are fixed by the bore.

Where the Airtac SAUD Double Rod Cylinder SAUD50X105S Is Used
Twin-Tool Transfer
Drives two synchronized workpieces from one compact body, keeping force identical in both extend and retract motions.
Lift and Lower Station
Lifts up to 42 kg vertically with a 2:1 safety margin, using the back rod to trigger a rear-mounted position switch.
Anti-Rotation Clamp
Prevents mechanical twist during clamping without external guides, ensuring precise downstroke pressure every cycle.
Is the Airtac SAUD Double Rod Cylinder SAUD50X105S the Right Cylinder?
When sizing this 50 mm bore, the neighboring 40 mm yields 528 N and the 63 mm yields 1402 N, both equal in both directions at 0.5 MPa. Select this double-rod unit when your mechanism requires anti-rotation guidance, needs to drive twin tooling, or benefits from back-end sensing. Mounting is limited to Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. At a 105 mm stroke, side loads are minimal, but for any stroke over 300 mm you should use external guide rails to prevent binding. The -S magnet allows electronic or reed switch placement along the profile slot.
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 SAUD50X105S FAQ
The force is equal both ways because a rod exits both ends. It produces 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers equally.
No, a plain double-rod cylinder drifts without live air, as the adjustable 21 mm cushions only decelerate near stroke end. For a held load, install an external rod lock or pilot-operated check valve.
