Airtac SAUD Double Rod Cylinder SAUD50X250
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X250 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 250mm 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 SAUD50X250
The AirTAC SAUD50X250 is a double-acting, double-rod profile cylinder with a 50 mm bore and 250 mm stroke. Because a rod protrudes from both ends, the push and pull force is equal at 825 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This unit uses a 1/4 inch port and M16x1.5 rod thread. With a 0.5 MPa input, the safe working load is about 495 N, yielding a vertical lift capacity of roughly 42 kg with a 2:1 margin. A high-temperature Viton H seal option extends operation up to 150 C. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD50X250 Is Used
Twin-Tool Transfer
Drives two opposing pick-and-place heads simultaneously from one piston, ensuring perfectly mirrored travel for compact assembly stations.
Balanced Lift Stage
Lifts small platens vertically without the asymmetric sag of single-rod units, using the equal 825 N force to keep the platform level.
Non-Rotating Clamp
Holds workpieces flat during machining by using the dual rods to resist torsional twist that would skew a standard round-body actuator.
Is the Airtac SAUD Double Rod Cylinder SAUD50X250 the Right Cylinder?
Select this 50 mm bore (825 N both ways) when you need synchronized motion or anti-rotation guidance. If you need less force, the 40 mm bore delivers 528 N both ways; for more power, the 63 mm bore provides 1402 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. For this 250 mm stroke, ensure external guide rails support any side loads to prevent binding. To add sensing, choose the -S variant, as this plain version cannot hold a load without live air and requires an external rod lock for fail-safe holding.
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 SAUD50X250 FAQ
The force is equal in both directions because of the double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The unit features a 1/4 inch port and operates at 30-800 mm/s.
No, the adjustable 21 mm air cushions only decelerate the piston near the stroke ends; they do not lock the position. For fail-safe load holding on air loss, you must fit an external rod lock or pilot-operated check valve.
