About the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-30
The AirTAC SAUJ100X75-30 is a double-acting double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 75mm nominal stroke by up to 30mm, yielding a usable 45-75mm working window. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet and cannot take 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 SAUJ100X75-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 45-75mm extend position for pressing bearings without swapping mechanical hard stops.
Variable Depth Sealing
Adjusts the extend end point on the fly to accommodate different box heights on a packaging line.
Prototype Actuation
Provides a 30mm trim window to test multiple extend lengths during fixture development before finalizing dimensions.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-30 the Right Cylinder?
Choose the SAUJ over a fixed SAU when your assembly requires field tuning of the extend end position without buying new hardware. Mounting options include Basic, FA flange, and LB foot, matching the AirTAC SC series. For strokes over 300mm, use external guides to prevent side-load damage. This non-magnet version cannot accept CMSG or DMSG switches.
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 SAUJ100X75-30 FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, pushes 5497N at 0.7MPa, 7068N at 0.9MPa, with an 801kgf max at 1.0MPa. The 75mm nominal extend stroke can be shortened by up to 30mm via the external stop screw, giving a 45-75mm working range.
The external stop screw mechanically sets the extend end position but is not a load lock. The 29mm air cushions only decelerate the piston near the end. Without live air the cylinder drifts, so use an external rod lock or pilot-operated check valve for held loads. This non-S SKU cannot take magnetic sensors.
