Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-100S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-100S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 800mm stroke, 1/2" 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 SAUJ100 Adjustable Cylinder SAUJ100X800-100S
The AirTAC SAUJ100X800-100S is a double-acting, single-rod profile cylinder with an 800 mm maximum extend stroke. An external stop screw lets you trim the extend stroke on-site by up to 100 mm, yielding a usable working stroke of 700 to 800 mm without buying a new actuator. It features a hard-anodized extruded aluminum barrel, making it shorter than an ISO 15552 cylinder of the same 100 mm bore. The 1/2" port and M20x1.5 rod thread handle serious pneumatic flow.
This 100 mm bore generates 3927 N of push force and 3681 N of pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push figure), translating to a 200 kg vertical lift with a 2:1 safety margin. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. Adjustable 29 mm cushions decelerate the payload, but the stop screw only sets end position—it is not a load lock.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-100S Is Used
Pallet Diverting Gate
Needs field stroke tuning to accommodate varying pallet widths without swapping actuators during line changeovers.
Vertical Material Lift
Requires precise extend endpoint adjustments at different shelf heights, relying on the 100 mm stop screw window.
Press Pinning Station
Demands exact extend positioning for seating components, using the adjustable stop to dial in final depth.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-100S the Right Cylinder?
When sizing this actuator, step down to an 80 mm bore if your 0.5 MPa push requirement is below 2513 N, or step up if you exceed 7068 N at 0.9 MPa. Choose the SAUJ over a fixed SAU when your machine assembly requires field tuning of the extend endpoint within the 100 mm window. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. The -S magnet enables electronic or reed sensing. Because the 800 mm stroke is long, always use an external guide to prevent rod bending and manage side loads. For dead-load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates.
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 SAUJ100 Adjustable Cylinder SAUJ100X800-100S FAQ
This 100 mm bore cylinder delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The nominal 800 mm extend stroke can be shortened by up to 100 mm on-site via an external stop screw, giving a 700-800 mm working window. It uses a 1/2" port.
The -S suffix indicates a built-in piston magnet for direct mounting of CMSG, DMSG, or EMSG sensors. The external stop screw physically limits the extend stroke to your desired length within the 100 mm window. It sets the end position but does not lock the load; without live air pressure the piston drifts, so use a pilot-operated check valve for holding.
