Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-40
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X75-40 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 SAUJ100X75-40
The AirTAC SAUJ100X75-40 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the nominal 75 mm stroke by up to 40 mm, yielding a usable working range of 35-75 mm without buying a new actuator. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG 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 SAUJ100X75-40 Is Used
Press Fit Tuning
Allows operators to dial in the exact 35-75 mm extend position for seating bearings without swapping actuators.
Diverter Gate Adjustment
Fine-tunes the extend stop on-site to alter package routing angles for varying product sizes.
Variable Forming Depth
Adjusts the extend stroke limit on-site to accommodate different carton forming depths on the fly.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-40 the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine build requires field-tuning of the extend end position within that 35-75 mm window. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because this specific SKU has no -S magnet, it cannot support position sensing. For any stroke, manage side loads with external guides; a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
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 SAUJ100X75-40 FAQ
The theoretical max is 801 kgf at 1.0 MPa. The nominal 75 mm extend stroke can be shortened by up to 40 mm via an external stop screw, giving a usable range of 35-75 mm. It uses a 1/2 inch port.
The external stop screw mechanically limits the piston's extend travel, letting you set the end position on-site. This stop is not a load lock. A plain cylinder drifts on air loss, and the 29 mm air cushions only decelerate the piston near stroke end. For secure load holding, install an external rod lock or pilot-operated check valve.
