Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-30S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-30S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 80mm 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 SAUJ100X80-30S
The AirTAC SAUJ100X80-30S is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the 80 mm nominal stroke by up to 30 mm, yielding a usable 50-80 mm working window. It features a hard-anodized extruded aluminum barrel, making it noticeably shorter than an ISO 15552 cylinder of the same bore. The 1/2" port and M20x1.5 rod thread handle heavy loads.
The -S suffix means a built-in magnet supports CMSG, DMSG, or EMSG sensors. If high heat is an issue, Viton H seals raise the operating range 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 SAUJ100X80-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 50-80 mm extend position for inserting bearings without changing hard stops.
Variable Flap Folding
Adjusts the extend end point on the fly to accommodate different carton depths on a shared packaging line.
Pallet Stop Positioning
Fine-tunes the stop screw to set precise pallet alignment distances before stretch wrapping occurs.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-30S the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine assembly requires precise end-position tuning without buying multiple cylinders. The 30 mm adjust window is ideal for final mechanical timing. Mounting options include Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for end-of-stroke confirmation. For any stroke length, always guide the load to prevent side-load wear on the rod seals.
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 SAUJ100X80-30S 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 80 mm nominal extend stroke can be shortened by up to 30 mm via the external stop screw, giving a 50-80 mm working range. It uses a 1/2" port and has 29 mm adjustable air cushions.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG sensors. Note that a plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates near the end. The stop screw sets the end position but is not a load lock. For secure holding, use an external rod lock or pilot-operated check valve.
