About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30
The AirTAC SAIJ100X80-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 80 mm stroke that can be dialed back by up to 30 mm, creating a precise 50-80 mm usable travel window for fine-tuning end positions during commissioning.
Delivering 3927 N of push force at 0.5 MPa (and up to 7068 N at 0.9 MPa), it features a 25 mm carbon steel rod and M20x1.5 rod thread for high side-load tolerance. The extruded aluminum barrel includes sensor grooves on both sides, and mounting is limited to the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30 Is Used
Machine Changeover
Dial in the 50-80 mm travel window during product size changes without replacing the entire cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end-position at commissioning using the rear stopper, ensuring precise alignment before final lock-down.
Assembly Pressing
Leverage the 7068 N push force at 0.9 MPa for pressing operations, adjusting the stroke depth accurately for varied component heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30 the Right Cylinder?
Choose this 100 mm bore when the 80 mm model's 5497 N push force at 0.9 MPa is insufficient, or step down if a 63 mm bore (2182 N at 0.7 MPa) is enough. An adjustable stroke is preferred over a fixed SAI when you need variable end-stops for product changeovers without swapping cylinders. To match this ISO 15552 unit, specify PT ports, a 30 mm adjustment, and no magnet.
The rear adjuster acts strictly as a travel stop to decelerate the load, not a lock. For position holding without live air pressure, use an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30 FAQ
The rear adjusting screw acts as a mechanical stopper that shortens the effective travel. For this model, the 80 mm nominal stroke can be trimmed back by up to 30 mm, providing a usable travel window of 50-80 mm.
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
