Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 80mm 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 SAUJ100X80-50
The AirTAC SAUJ100X80-50 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site. The nominal 80 mm stroke is the maximum, yielding a usable extend range of 30-80 mm. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore generates a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. A practical computed insight: the safe working load is roughly 2356 N (about 60% of the 0.5 MPa push figure), allowing a vertical lift of approximately 200 kg with a 2:1 safety margin. If your machine needs high-temperature operation up to 150 C, you can specify the Viton H seal option instead of the standard NBR.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50 Is Used
Press Fit Tuning
Allows operators to dial in the exact 30-80 mm extend position for seating bearings without swapping cylinders.
Variable Carton Flap Folding
Adjusts the extend stroke on-site to accommodate different box depths on a shared packaging line.
End-of-Line Stopper Gates
Provides a field-tunable physical stop for pallets, letting maintenance shorten the gate extension by up to 50 mm.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50 the Right Cylinder?
When sizing this actuator, compare it against the neighboring 80 mm bore, which provides 2513 N push at 0.5 MPa, and ensure your pressure requirements match the 100 mm bore's 3927 N push at 0.5 MPa (5497 N at 0.7 MPa). Choose this SAUJ model over a fixed-stroke SAU when your assembly requires minor extend-length adjustments without buying new hardware. The external stop screw provides a 50 mm trim window. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. For any stroke application, always guide the load to prevent side-loading; use external linear rails for long strokes. Note that the stop screw sets end position only and does not lock the load.
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 SAUJ100X80-50 FAQ
At 0.5 MPa this 100 mm bore cylinder pushes with 3927 N and pulls with 3681 N. Push force is 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and the theoretical max is 801 kgf at 1.0 MPa. The nominal 80 mm extend stroke is the maximum; the external stop screw lets you shorten it by up to 50 mm on-site, giving a usable range of 30-80 mm.
No, this SKU lacks the -S magnet, so it cannot accept magnetic switches. A plain cylinder does not hold a load on air loss; the piston drifts and the 29 mm air cushion only decelerates near the stroke end. The stop screw sets the end position but is not a brake. For a held load, install an external rod lock or a pilot-operated check valve.
