Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X750-75 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 SAUJ100X750-75
The AirTAC SAUJ100X750-75 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 750 mm nominal travel by up to 75 mm, yielding a usable range of 675-750 mm. This bore features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.
It operates at 30-800 mm/s and accepts pressures up to 1.0 MPa. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For elevated thermal demands, a Viton H seal option extends 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 SAUJ100X750-75 Is Used
Press Stroke Calibration
Allows operators to fine-tune the 750 mm extend stroke by up to 75 mm on-site to accommodate different material thicknesses in a forming press without changing tooling.
Variable Length Diverter
Ideal for diverting packages of varying sizes on a heavy-duty conveyor, where the external stop screw quickly adjusts the pusher end position for specific box lengths.
Pallet Positioning Gate
Provides adjustable reach for a pallet handling gate, letting maintenance crews trim the extend stroke by up to 75 mm to align with changing pallet dimensions.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75 the Right Cylinder?
If your application requires less force, the 80 mm version saves space; if you need more than 3927 N, you are at the top of the SAUJ range. Choose the SAUJ over a fixed SAU cylinder when your machine build requires field-tuning of the end position without buying a new actuator. The 75 mm adjust window is ideal for accommodating minor mechanical variations or fine-tuning clamping distance. Mounting options include Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. Because this SKU lacks the -S suffix, it cannot support magnetic sensing. Finally, at a 750 mm stroke, the 25 mm rod is highly susceptible to side-loading; always use external guide rails to prevent rod bending and premature seal wear.
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 SAUJ100X750-75 FAQ
At 0.7 MPa the push is 5497 N, and at 0.9 MPa it is 7068 N, with a theoretical maximum of 801 kgf at 1.0 MPa. The nominal 750 mm extend stroke can be shortened by up to 75 mm via an external stop screw, giving a usable range of 675-750 mm. It features a 1/2" port and 29 mm adjustable cushions.
No, a plain SAUJ cylinder cannot hold a load without live air. The piston will drift if pressure drops or the valve is centered. The external stop screw only sets the end position, and the air cushion solely decelerates the piston near the stroke end; neither acts as a load lock or brake. For load-holding applications, you must install an external rod lock or a pilot-operated check valve.
