Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-40S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X750-40S 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 SAUJ100X750-40S
The AirTAC SAUJ100X750-40S 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 40 mm, giving a usable extend range of 710-750 mm. The 750 mm nominal stroke is the maximum. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. For high-heat environments up to 150 C, Viton H seals are available.

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 SAUJ100X750-40S Is Used
Press Fit Tuning
Allows operators to dial in the exact 710-750 mm extend position on-site for seating bearings without re-engineering the fixture.
Pallet Stop Adjustment
Provides a field-adjustable hard stop for varying pallet lengths on a heavy-duty 100 mm bore transfer line.
Heavy Lift Diverter
Handles large vertical loads up to 200 kg safely while permitting micro-adjustments to the diverting stroke end-point.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-40S the Right Cylinder?
If 3518 N suffices, step down to save space and air. Choose the SAUJ over a fixed SAU when your machine assembly requires field tuning of the extend endpoint without buying a new cylinder. The 40 mm adjust window is ideal for final mechanical timing. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because the -S magnet is present, you can directly mount reed or electronic switches. 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 SAUJ100X750-40S FAQ
Push force is 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. The nominal 750 mm extend stroke can be shortened by up to 40 mm via the external stop screw, yielding a 710-750 mm usable range.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The external stop screw sets the extend end position but is not a load lock. The cylinder does not hold load on air loss; the 29 mm air cushion only decelerates the piston. For load holding, use an external rod lock or pilot-operated check valve.
