Airtac SAUD Double Rod Cylinder SAUD50X45S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X45S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 45mm 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 SAUD50X45S
The AirTAC SAUD50X45S is a double-acting, double-rod profile cylinder. A 20mm rod exits both ends, meaning both faces use the rod-side piston area to deliver an identical 825 N output in both directions at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same 50mm bore.
This 45mm stroke unit features a 1/4" port and an M16x1.5 rod thread. Because it carries the -S suffix, it includes a piston magnet for CMSG, DMSG, or EMSG switches. The rear rod can also drive a second tool or carry a switch cam. For sizing, expect a safe working load around 495 N, or a vertical lift capacity of roughly 42 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD50X45S Is Used
Synchronized Transfer
Drives two parallel pick-and-place fingers simultaneously from one piston, keeping tooling perfectly aligned without torsional twist.
Anti-Rotation Clamping
Applies 825 N of clamping pressure through a dual-rod structure that resists rotational drift during precision machining tasks.
Rear-Cam Sensing
Uses the extended back rod to trip an external limit switch or mount a CMSG sensor cam when front-end space is restricted.
Is the Airtac SAUD Double Rod Cylinder SAUD50X45S the Right Cylinder?
Choose this 50mm bore if you need 825 N of equal push and pull force. Stepping down, the 40mm bore yields 528 N each way; stepping up, the 63mm bore provides 1402 N. A double rod is ideal for anti-rotation guidance, twin-tool driving, or back-end sensor mounting. It supports Basic, FA flange, and LB foot mounts compatible with the AirTAC SC series. The -S magnet allows electronic or reed sensing. With a 45mm stroke, side loads are minimal, but always use external guides for longer travels.
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 SAUD50X45S FAQ
The force is equal in both directions because rods protrude from both ends. It delivers 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
No, the air cushions only decelerate the piston near the stroke ends. For load holding on air loss, you must fit an external rod lock or a pilot-operated check valve.
