Airtac SAUJ100 Adjustable Cylinder SAUJ100X700-75S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X700-75S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 700mm 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 SAUJ100X700-75S
The AirTAC SAUJ100X700-75S is a double-acting, double-rod profile cylinder with a 700 mm maximum stroke. An external stop screw lets you trim the extend stroke on-site by up to 75 mm, yielding a usable working range of 625 to 700 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors.
Choose this adjustable unit over a fixed SAU when you need precise field tuning without buying a new cylinder. For high-temperature environments up to 150 C, select the Viton H seal option.

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 SAUJ100X700-75S Is Used
Large Press Dwell Tuning
Allows operators to fine-tune the exact extend position of a large forming press on-site, adjusting up to 75 mm to accommodate different material thicknesses without changing tooling.
Heavy Pallet Diverting
Provides robust diverting force for heavy pallets, letting maintenance shorten the extend stroke by up to 75 mm to match new lane widths or physical guards installed later.
Variable Height Stacking
Ideal for automated stacking machines where the extend reach must be adjusted in the field to handle varying pallet heights while maintaining high pushing force.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X700-75S the Right Cylinder?
If your application only needs 2000 N, step down to save space and air. Select the SAUJ over a standard fixed SAU cylinder when your machine assembly requires on-site extend length tweaking within the 75 mm window. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because the -S magnet is present, you can directly mount CMSG, DMSG, or EMSG switches for end-of-stroke detection. Since the stroke is 700 mm, you must support the load with external guides 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 SAUJ100X700-75S FAQ
The nominal 700 mm stroke is the maximum; the external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable range of 625 to 700 mm. It uses a 1/2 inch port.
The external stop screw mechanically sets the extend end position, but it is not a load lock. A plain cylinder does not hold a load on air loss or when the valve is centered; the piston drifts, and the 29 mm air cushions only decelerate the piston near the end of the stroke. For true load holding, you must install an external rod lock or a pilot-operated check valve.
