Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X800-30S 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 SAUJ100X800-30S
The AirTAC SAUJ100X800-30S is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 30 mm, yielding a usable 770 to 800 mm extension. The extruded aluminum profile is notably shorter than an ISO 15552 cylinder of the same bore.
This bore size provides a theoretical maximum force of 801 kgf at 1.0 MPa. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position sensing. High-temperature Viton H seals can extend the operating range up to 150 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 770 to 800 mm extend position for seating heavy bearings, compensating for material thickness variations on-site.
Pallet Stop Adjustment
Provides a adjustable hard stop for varying pallet lengths on a 100 mm bore actuator, letting maintenance shorten the extend stroke by up to 30 mm as needed.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30S the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine assembly requires minor end-position tweaking without buying a new cylinder. The 30 mm adjust window is ideal for fine-tuning press fits or clamping reach. Basic, FA flange, and LB foot mountings are available, sharing compatibility with the AirTAC SC series. The -S magnet supports CMSG/DMSG/EMSG sensors. Because the 800 mm stroke is long, always use external guides to prevent rod bending and manage side loads.
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 SAUJ100X800-30S FAQ
Push force is 5497 N 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 30 mm via the external stop screw, giving a 770 to 800 mm working window.
The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG electronic switches. Note that the stop screw only sets the end position; it is not a load lock. On air loss, the cushion only decelerates but cannot hold the load. For secure load holding, use an external rod lock or pilot-operated check valve.
