Airtac SAUD Double Rod Cylinder SAUD50X80
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X80 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 80mm 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 SAUD50X80
The AirTAC SAUD50X80 is a double-acting, double-rod profile cylinder with an 80 mm stroke. A rod protrudes from both ends, meaning the push and pull output is identical at 825 N each way at 0.5 MPa. The extruded aluminium body is noticeably shorter than a standard ISO 15552 unit of the same bore. It uses a 1/4 inch port and an M16x1.5 rod thread.
Because the piston travels on two rods, it resists torsional twist for non-rotating duties. This configuration is also ideal when you need to drive twin tooling or mount a cam on the back rod. Based on the 825 N figure, your safe working load is roughly 495 N, which translates to a vertical lift capacity of about 42 kg with a 2:1 safety margin. Note this SKU lacks a magnet, so it cannot host CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD50X80 Is Used
Twin-Tool Stamping
Drives two identical forming punches simultaneously from one piston, ensuring perfectly synchronized striking pressure.
Anti-Rotation Lift
Lifts and lowers delicate electronic trays without torsional drift, using the dual rods to maintain strict parallel alignment.
Dual-End Transfer
Pushes a product forward while engaging a secondary mechanism with the rear rod, saving space on the transfer line.
Is the Airtac SAUD Double Rod Cylinder SAUD50X80 the Right Cylinder?
Select this 50 mm bore if your application demands equal force in both directions, yielding 825 N at 0.5 MPa. Step down to a 40 mm bore for 528 N, or up to a 63 mm bore for 1402 N when more thrust is required. The twin-rod layout is the right call for anti-rotation guidance, synchronized dual-tool driving, or rear-rod actuation. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At an 80 mm stroke, side loads are minimal, but always guide the load externally on longer movements. Remember this non-magnetic variant cannot accept position switches.
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 SAUD50X80 FAQ
The force is equal in both directions because it is a 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 1/4 inch port supplies air to both chambers equally.
No. The adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston will drift. Use an external rod lock or a pilot-operated check valve for secure load holding.
