Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-50S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X75-50S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 75mm 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 SAUJ100X75-50S
The AirTAC SAUJ100X75-50S is a double-acting double-rod profile cylinder built for on-site stroke adjustment. An external stop screw lets you trim the extend stroke by up to 50 mm, giving a usable working range of 25 to 75 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It includes a 1/2 inch port, M20x1.5 rod thread, and a built-in magnet for position sensing.
The adjustable 29 mm air cushions decelerate the payload smoothly. You can mount CMSG, DMSG, or EMSG sensors directly thanks to the -S suffix.

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 SAUJ100X75-50S Is Used
Press Fit Tuning
Dialing in precise insertion depths for bearing presses. The 50 mm stop screw window allows operators to adjust the extend endpoint on-site for varying part tolerances.
Variable Height Sealing
Applying consistent downward pressure on carton sealers. The adjustable stroke accommodates different package sizes without repositioning the entire actuator assembly.
Pallet Positioning Stops
Acting as a movable end stop for pallet handling lines. The extend stroke can be shortened by up to 50 mm to adapt to new pallet footprints quickly.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-50S the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machinery requires slight extend-position tweaks during commissioning without buying a new cylinder. The 50 mm adjust window is ideal for dialing in exact endpoints. Basic, FA, and LB mounting options are available, sharing compatibility with the AirTAC SC series. Because the -S magnet is present, you can fit reed or electronic switches. For strokes at or over 300 mm, always use an external guide to prevent side-load 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 SAUJ100X75-50S FAQ
The theoretical max is 801 kgf at 1.0 MPa. The nominal extend stroke is 75 mm, but the external stop screw allows you to shorten it by up to 50 mm on-site, yielding a usable 25 to 75 mm range.
The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection. 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. For secure load holding, use an external rod lock or pilot-operated check valve.
