Airtac SAUD Double Rod Cylinder SAUD63X850
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X850 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 850mm 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 SAUD63X850
The AirTAC SAUD63X850 is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both faces use the rod-side area. The output force is equal in both directions, delivering 1402 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port and M16x1.5 rod threads.
This 63 mm bore model provides a computed safe working load of roughly 841 N, which is about 60 percent of the 0.5 MPa figure. This translates to a vertical lift capacity of approximately 71 kg with a 2:1 safety margin. The unit includes adjustable air cushions at both ends to decelerate the piston. For high-temperature environments up to 150 C, you can specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD63X850 Is Used
Synchronized Transfer
Drives a dual-sided conveyor pusher where the second rod links a slave carriage, keeping motion perfectly synchronized over the 850 mm travel.
Twin-Spindle Lifting
Raises and lowers a twin-spindle machining head. The equal push and pull force ensures stable vertical positioning without twist.
Dual-Clamp Gantry
Operates opposing clamps on a storage gantry. The dual rods carry separate jaws to grip pallets from both sides simultaneously.
Is the Airtac SAUD Double Rod Cylinder SAUD63X850 the Right Cylinder?
Choose this 63 mm bore if your application requires anti-rotation guidance, twin tooling, or a back-end sensor cam. It delivers 1402 N of equal force both ways at 0.5 MPa. If you need less force, the 50 mm bore provides 825 N both ways. If you need more, the 80 mm bore offers 2268 N both ways. Mounting is limited to Basic, FA, and LB styles, compatible with the AirTAC SC series. Because this is an 850 mm stroke, you must use external guides to prevent rod bending and side loads. This SKU lacks a magnet, so it cannot take a magnetic switch.
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 SAUD63X850 FAQ
The force is equal in both directions because it is a double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The 3/8 inch port supplies air to both chambers.
No. A plain double-rod cylinder drifts on air loss or when the valve is centered. The adjustable cushion only decelerates near the stroke end. Use an external rod lock or pilot-operated check valve to hold a load.
