Airtac SAUD Double Rod Cylinder SAUD50X900
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X900 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 900mm 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 SAUD50X900
The AirTAC SAUD50X900 is a double-acting, double-rod profile cylinder with a 50 mm bore and 900 mm stroke. A rod protrudes from both ends, meaning push and pull forces are identical at 825 N each way at 0.5 MPa. The extruded aluminium profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It uses a 1/4 inch port and has an M16x1.5 rod thread.
Because both faces use the rod-side area, the effective safe working load is roughly 495 N, which translates to a vertical lift capacity of about 42 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors. For high heat environments, a Viton H seal option extends the operating range up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X900 Is Used
Twin Tool Transfer
Drives two opposing grippers simultaneously with equal 825 N force, keeping synchronous pick and place timing without external linkages.
Anti-Rotation Edge Guide
Uses the dual rods to resist torsional twist during long 900 mm traverses on packaging conveyors, maintaining precise web alignment.
Symmetrical Clamping
Applies identical clamping pressure from both ends of a workstation fixture, ensuring components stay centred during machining.
Is the Airtac SAUD Double Rod Cylinder SAUD50X900 the Right Cylinder?
When sizing this double-rod unit, compare it both ways: step down to a 40 mm bore for 528 N, or up to a 63 mm bore for 1402 N, both equal in each direction. Choose the SAUD50X900 when your mechanism requires anti-rotation guidance, drives twin tooling, or needs a back rod to trip a switch. Mounting is limited to Basic, FA flange and LB foot options, matching the AirTAC SC series. Because the stroke is 900 mm, you must use external guides to prevent rod bending and side-load damage. Note this non-magnetic version cannot host position 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 SAUD50X900 FAQ
Force is equal both ways because rods exit both ends. It delivers 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4 inch port feeds both chambers identically.
No. The air cushions only decelerate the piston near stroke end; they do not act as a brake. The piston will drift on air loss. For load holding, install an external rod lock or pilot-operated check valve.
