Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-20
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X75-20 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 SAUJ100X75-20
The AirTAC SAUJ100X75-20 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 20 mm, giving a usable extend range of 55 to 75 mm. The nominal 75 mm stroke acts as the maximum travel. It features a 1/2 inch port and an M20x1.5 rod thread.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. It includes 29 mm adjustable air cushions. 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 SAUJ100X75-20 Is Used
Press Fit Stations
Needs field stroke tuning to set precise 60 mm pressing depth for delicate bearing seating without reordering actuators.
Diverter Gates
Requires adjusting the extend stroke by 15 mm on-site to perfectly clear new package profiles on the line.
Carton Formers
Demands exact end-position tweaking to accommodate varying cardboard thicknesses during the folding cycle.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-20 the Right Cylinder?
When sizing this actuator, compare both neighbors and forces. Dropping to an 80 mm bore reduces the 0.5 MPa push to 2513 N, while a 100 mm bore provides 3927 N. Choose the SAUJ over a fixed SAU when your machine build requires minor on-site stroke tuning without buying a new cylinder. The 20 mm adjust window is ideal for final positioning tweaks. It supports basic, FA, and LB mounts, sharing compatibility with the AirTAC SC series. Because this specific SKU has no -S magnet, it cannot take sensors. For any stroke, manage side loads with external guides. Remember the stop screw sets end position but is not a load lock.
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 SAUJ100X75-20 FAQ
Push force is 5497 N at 0.7 MPa and 7068 N at 0.9 MPa. The theoretical max is 801 kgf at 1.0 MPa. The external stop screw shortens the extend stroke by up to 20 mm, yielding a 55 to 75 mm usable window.
An external stop screw mechanically limits the piston extension, letting you trim travel on-site. This stop sets the end position but is not a load lock. A plain cylinder drifts on air loss, and the 29 mm cushions only decelerate. For held loads, use an external rod lock or pilot-operated check valve.
