Airtac SAUJ100 Adjustable Cylinder SAUJ100X145-30
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X145-30 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 145mm 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 SAUJ100X145-30
The AirTAC SAUJ100X145-30 is a double-acting single-rod profile cylinder with an on-site stroke adjustment window. An external stop screw lets you shorten the extend stroke by up to 30 mm, giving a usable range of 115-145 mm. The 145 mm nominal stroke is the maximum. This bore uses a 1/2 inch port and a 25 mm rod. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.
Force output is substantial: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. A practical computed insight sets the safe working load near 2356 N, allowing a vertical lift of roughly 200 kg with a 2:1 margin. The 29 mm adjustable air cushions decelerate the piston near end positions. This non-magnet SKU cannot take a sensor.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X145-30 Is Used
Press Fit Calibration
Allows operators to dial in the exact 115-145 mm extend position for seating bearings without machining custom spacers.
Variable Length Diverter
Adjusts the extend stop on-site to deflect different package sizes on a packaging line by up to 30 mm.
Pallet Stop Positioning
Fine-tunes the mechanical end stop for pallets of varying widths without needing to swap out the entire actuator.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X145-30 the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while this model delivers 3927 N. Choose the SAUJ adjustable type over a fixed SAU when your machine assembly requires field tuning of the extend end position within that 30 mm window. Basic, FA flange, and LB foot mountings are available, sharing compatibility with the AirTAC SC series. Because this specific SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors. For any stroke over 300 mm, always use external guide rails to prevent side-load damage.
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 SAUJ100X145-30 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push rises to 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 shortens the extend stroke by up to 30 mm, giving a usable range of 115-145 mm.
The external screw sets the extend end position mechanically. It is not a load lock. A plain cylinder drifts on air loss, and the 29 mm cushions only decelerate the piston near the end. For secure load holding, add an external rod lock or pilot-operated check valve.
