Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-20S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X750-20S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 750mm 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 SAUJ100X750-20S
The AirTAC SAUJ100X750-20S is a double-acting, double-rod profile cylinder with an external stop screw that lets you shorten the extend stroke by up to 20 mm on-site. This yields a usable extend range of 730-750 mm for the 750 mm nominal maximum. The extruded aluminum profile barrel is purposefully shorter than an ISO 15552 cylinder of the same 100 mm bore. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG position sensing.

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 SAUJ100X750-20S Is Used
Press Fit Alignment
Finalizing insertion depth for heavy bearings where a 20 mm external stop adjustment dials in the exact end position during machine commissioning.
Pallet Stopper Gate
Actuating a heavy-duty flow control gate that needs minor 730 to 750 mm stroke trimming to accommodate varying pallet thicknesses on the line.
Vertical Lift Platform
Raising a 200 kg materials tray using the 0.5 MPa thrust, relying on the magnetic piston for precise height confirmation at the trimmed endpoint.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-20S the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine assembly requires slight on-site extend length tuning without buying a new cylinder. The 20 mm adjust window is ideal for minor mechanical alignment. Basic, FA, and LB mountings are available, sharing compatibility with the AirTAC SC series. Because the -S magnet is present, you can directly mount reed or electronic sensors. For this long 750 mm stroke, always use an external guide 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 SAUJ100X750-20S FAQ
Push increases to 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 750 mm nominal extend stroke can be shortened by up to 20 mm via the external stop screw, giving a 730-750 mm usable range.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG position switches. Note that a plain cylinder does not hold load on air loss; the piston drifts and the 29 mm cushions only decelerate near stroke end. The stop screw sets the end position but is not a lock. For held loads use an external rod lock or pilot-operated check valve.
