Airtac SAUD Double Rod Cylinder SAUD63X155
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X155 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 155mm stroke, 3/8" 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 SAUD63X155
The AirTAC SAUD63X155 is a double-acting, double-rod profile cylinder featuring a 63 mm bore and 155 mm stroke. Because a rod exits both ends, the push and pull force is identical, yielding 1402 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same size. It features a 3/8" port and M16x1.5 rod thread.
This twin-rod design provides excellent anti-rotation guidance and lets you mount tooling on both ends simultaneously. Based on the 1402 N output, the safe working load is roughly 841 N, translating to a vertical lift capacity of about 71 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, you can specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X155 Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from opposite rod ends, ensuring perfectly balanced feed rates without rotational twist.
Dual Transfer Pusher
Pushes parts on parallel conveyor lanes simultaneously, using the equal force to maintain synchronous timing across the line.
Balanced Lift Platform
Raises and lowers a light fixture jig with identical force in both directions, preventing sagging during vertical return strokes.
Is the Airtac SAUD Double Rod Cylinder SAUD63X155 the Right Cylinder?
Selecting this 63 mm bore model gives 1402 N of equal bidirectional force at 0.5 MPa. If you need less power, the 50 mm bore provides 825 N both ways; for heavier duty, the 80 mm bore offers 2268 N. A double-rod configuration is the right call when your application demands strict anti-rotation accuracy, synchronized twin tooling, or a rear rod to act as a mechanical stop. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 155 mm stroke, side loads are minimal, but always use external guides for longer strokes. Remember that this non-magnetic version cannot support position sensing.
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 SAUD63X155 FAQ
The force is equal in both directions due to the double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It uses a 3/8" port and never quotes a larger single-rod push value.
No, this SKU lacks a magnet (-S) and cannot accept magnetic switches. Additionally, the air cushion only decelerates the piston near stroke end; it will not hold a load on air loss. For suspended loads, install an external rod lock or pilot-operated check valve.
