Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-50S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X750-50S 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 SAUJ100X750-50S
The AirTAC SAUJ100X750-50S is a double-acting, double-rod profile cylinder with an on-site stroke adjustment window. An external stop screw lets you trim the extend stroke by up to 50 mm, yielding a usable working span of 700 to 750 mm. The 750 mm nominal length serves as the absolute maximum travel. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end.
Delivering robust thrust, this 100 mm bore unit pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 7068 N at 0.9 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors.

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 SAUJ100X750-50S Is Used
Press Tonnage Calibration
Needs field stroke tuning to set precise lower dead center on varying material thicknesses without reprogramming the motion controller.
Package Diverter Arms
Requires adjusting the extend endpoint on-site to accommodate different box widths without changing out the entire actuator assembly.
Pallet Positioning Stops
Demands a flexible physical stop to dial in the exact pallet edge location during line layout changes or product family shifts.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-50S the Right Cylinder?
Choose the SAUJ over a fixed SAU cylinder when your machine assembly requires minor end-position tweaking without buying new hardware. The 50 mm adjust window is ideal for dialing in exact endpoints. Mounting options include Basic, FA flange, and LB foot, sharing compatibility only with the AirTAC SC series. Because the 750 mm stroke is long, always use external guides to prevent rod bending and manage side loads. The -S magnet enables electronic or reed switch sensing.
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 SAUJ100X750-50S FAQ
This 100 mm bore cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushes 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 external stop screw allows you to shorten the extend stroke by up to 50 mm on-site, giving a usable travel range of 700 to 750 mm. It uses a 1/2 inch port.
The external stop screw mechanically limits the piston extension to set the end position. This mechanism is not a load lock. A plain cylinder drifts on air loss or when the valve is centered, and the 29 mm air cushions only decelerate the piston near the end of travel. To hold a load securely, you must add an external rod lock or a pilot-operated check valve.
