Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X700-75S
The AirTAC Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X700-75S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 700mm 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 SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X700-75S
The AirTAC SAUJ63X700-75S is a double-acting single-rod profile cylinder with a 63mm bore and a 700mm maximum extend stroke. An external stop screw lets you shorten the extend stroke on-site by up to 75mm, yielding a usable range of 625 to 700mm without buying a new actuator. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port, an M16x1.5 rod thread, and a built-in magnet for CMSG, DMSG, or EMSG sensors.
Force output is substantial: 1559N push and 1402N pull at 0.5MPa, scaling to 2805N push at 0.9MPa. For payload sizing, a safe working load is roughly 935N, which translates to a vertical lift capacity of about 79kg with a 2:1 safety margin. The adjustable air cushions decelerate the piston near the ends, but the stop screw only sets the end position and does not lock the load. For dead-air load holding, you must add an external rod lock or pilot-operated check valve.

Where the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X700-75S Is Used
Variable Length Stopper
Acts as a configurable end-stop on a machining line where the extend position must be dialed in precisely within the 75mm window to accommodate different material lengths.
Adjustable Diverter Gate
Controls a routing flap on a package conveyor, allowing maintenance teams to shorten the gate stroke on-site to handle varying box sizes without changing the actuator.
Tunable Pallet Arrestor
Functions as a pallet stopper in a high-throughput facility, using the external screw to tweak the stopping distance for different pallet configurations.
Is the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X700-75S the Right Cylinder?
Size this 63mm bore against its neighbors: a 50mm bore yields 982N push at 0.5MPa, while an 80mm bore provides 2513N. Choose the SAUJ63X700-75S over a fixed SAU when your machine assembly requires field-tuning of the extend endpoint within a 625 to 700mm window. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. The -S suffix means a piston magnet is present for position sensing. Because the 700mm stroke is long, ensure external guides support side loads to prevent rod bending. Operating pressure is 0.15-1.0MPa, with a Viton H seal option for high-temperature environments.

- ✓ 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 SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X700-75S FAQ
At 0.5MPa it provides 1559N push and 1402N pull force, scaling to 2182N at 0.7MPa and 2805N at 0.9MPa. The theoretical max is 318kgf at 1.0MPa. The 700mm extend stroke can be shortened by up to 75mm on-site using the external stop screw, giving a usable range of 625 to 700mm. It uses a 3/8 inch port.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG electronic or reed switches. The stop screw and air cushions only manage end positioning and deceleration; they do not hold the load. If air pressure drops, the piston drifts. For secure load holding, install an external rod lock or pilot-operated check valve.
