Airtac SAUJ100 Adjustable Cylinder SAUJ100X275-30
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X275-30 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 275mm 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 SAUJ100X275-30
The AirTAC SAUJ100X275-30 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 30 mm. You can trim the 275 mm nominal stroke down to 245 mm using the external stop screw, letting you dial in the exact end position without buying a new actuator. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This 100 mm bore generates a push of 3927 N and a pull 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), translating to a vertical lift capacity of approximately 200 kg with a 2:1 safety margin. The extruded aluminum profile is notably shorter than an ISO 15552 cylinder of the same bore, and the Viton H seal option extends operating temperature to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X275-30 Is Used
Press Fit Tuning
Dialing in a delicate press fit operation where the exact 245-275 mm extend endpoint must be set physically on the machine to accommodate material thickness variations.
Variable Depth Sealing
Adjusting the sealing head stroke on a packaging line to handle different container heights without reprogramming the motion controller or changing tooling.
Pallet Stop Calibration
Fine-tuning a heavy-load pallet positioning stop where the 100 mm bore provides the necessary 200 kg vertical lift force and the stop screw sets the precise resting location.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X275-30 the Right Cylinder?
When sizing this actuator, step down to an 80 mm bore if your required push at 0.7 MPa is under 3518 N, or step up if you need more than the 5497 N provided here at 0.7 MPa. Choose this SAUJ model over a fixed-stroke SAU when your assembly tolerance requires field tuning of the extend position within the 245-275 mm range. It supports Basic, FA flange, and LB foot mounts, with mounting compatibility matching the AirTAC SC series. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensors. At a 275 mm stroke, ensure external guide rails carry any side loads to prevent rod binding.
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 SAUJ100X275-30 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N push and 3681 N pull. Push force is 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 30 mm external stop screw window allows you to shorten the 275 mm extend stroke down to 245 mm on-site.
No, the stop screw only sets the end position; it is not a load lock. A plain double-acting cylinder drifts on air loss, and the 29 mm adjustable cushion only decelerates the piston near the end of travel. For secure load holding, you must add an external rod lock or a pilot-operated check valve.
