Airtac SAUD Double Rod Cylinder SAUD50X135
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X135 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 135mm 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 SAUD50X135
The AirTAC SAUD50X135 is a double-acting, double-rod profile cylinder. Because a rod exits both ends, the push and pull output is identical, delivering 825 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than a standard ISO 15552 unit of the same bore. It features a 1/4" port, a 20 mm piston rod, and M16x1.5 rod threads.
With a 135 mm stroke, this unit provides a computed safe working load of about 495 N and a vertical lift capacity near 42 kg with a 2:1 safety margin. You can mount it using basic, FA flange, or LB foot brackets that match the AirTAC SC series. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD50X135 Is Used
Twin-Tool Stamping
Drives two identical forming tools simultaneously from opposite rod ends to double production output per cycle.
Synchronized Diverting
Pushes a diverter arm from either side with equal 825 N force to keep belt sorting movements perfectly balanced.
Anti-Rotation Lifting
Raises and lowers heavy totes without twisting, using the dual rods to prevent rack binding during vertical transfers.
Is the Airtac SAUD Double Rod Cylinder SAUD50X135 the Right Cylinder?
Choose this 50 mm bore if you need 825 N of equal bidirectional force. Sizing down, the 40 mm bore yields 528 N both ways; sizing up, the 63 mm bore provides 1402 N. A double-rod design is the right call when you need anti-rotation guidance, want to drive twin tooling, or need a back rod to trip a switch. At 135 mm stroke, side loading is minimal, but always use external guides for longer travels. Remember that a plain cylinder drifts without live air, so add an external rod lock or pilot-operated check valve if you must hold a load vertically.
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 SAUD50X135 FAQ
The force is equal in both directions because both faces have a rod. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S option for sensing capabilities.
