Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-30
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-30 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 950mm 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 SAUJ100X950-30
The AirTAC SAUJ100X950-30 is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment window of 30 mm. You can trim the 950 mm nominal stroke down to 920 mm via an external stop screw. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end. The extruded aluminum profile barrel is noticeably 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. For design calculations, the safe working load is roughly 2356 N, and it can vertically lift about 200 kg with a 2:1 safety margin. Since this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors. The external stop sets the end position but does not lock the load; you need an external rod lock or pilot-operated check valve to hold position on air loss.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-30 Is Used
Press Tonnage Calibration
Needs field stroke tuning to set precise bottom-dead-center on a heavy press, using the 30 mm stop screw to dial in the exact 920-950 mm contact point without re-engineering the fixture.
Pallet Stop Positioning
Requires adjusting the extend stop on-site to accommodate varying pallet lengths, using the external screw to shorten the stroke and prevent overshoot on a high-thrust sorting line.
Heavy Tray Depalletizer
Demands exact end-position trimming during commissioning to lift 200 kg vertical loads safely, relying on the 100 mm bore profile barrel to save vertical space compared to standard ISO units.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-30 the Right Cylinder?
When sizing this actuator, look at both neighboring bores and the 0.5 MPa force class. An 80 mm bore gives 2513 N push, while this 100 mm unit yields 3927 N, escalating to 7068 N at 0.9 MPa. Choose the SAUJ over a fixed SAU when your machine assembly requires minor field tuning of the extend endpoint without buying a new cylinder. The 30 mm adjust window is ideal for final mechanical timing. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because the 950 mm stroke is long, always use external guides to prevent rod bending and manage side loads. This non-magnet SKU cannot support sensors.
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 SAUJ100X950-30 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force, reaching 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. It uses a 1/2 inch port with an M20x1.5 rod thread. The nominal 950 mm extend stroke can be shortened by up to 30 mm on-site via the external stop screw, yielding a usable range of 920-950 mm.
An external stop screw physically limits the piston's extend travel, letting you trim the endpoint by up to 30 mm without disassembly. This stop only sets the end position; it is not a load lock. The 29 mm air cushions merely decelerate the piston near the end. Because a plain cylinder drifts on air loss or when a valve is centered, you must use an external rod lock or pilot-operated check valve for load holding.
