About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-30
The AirTAC SAIJ100X170-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position. It provides a usable travel window of 140 to 170 mm, letting you dial back the stroke by up to 30 mm during commissioning without bolting on external stops. The 100 mm bore generates 3927 N of push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This unit features a SUS420J2 stainless steel piston rod (option A) for improved corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic sensors if a magnet is added later. Mounting options cover the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-30 Is Used
Product Changeover
Dial in the exact 140-170 mm end-stop during machine setup to accommodate different product lengths without swapping cylinders.
End-Position Tuning
Fine-tune the retract position during commissioning to align heavy fixtures precisely using the rear adjusting screw.
Heavy-Duty Clamping
Leverage the 3927 N push force at 0.5 MPa to secure heavy workpieces while adjusting the clamping depth as needed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-30 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust—stepping up to the 125 mm bore yields 6136 N at 0.5 MPa, while dropping to the 80 mm bore provides 2513 N. The adjustable stroke is ideal for product changeovers on a line where the exact end-stop position varies slightly. For load-holding without live air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock or a SAIL cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 170 mm stroke, 30 mm adjustment range, G1/2 port, and the desired mounting bracket. The 170 mm stroke is well within the 1500 mm standard maximum, so no external side-load guide is strictly required for normal loads, though the M20x1.5 rod thread handles robust connections.
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 SAIJ100AX170-30 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a travel stop, allowing you to shorten the 170 mm nominal stroke by up to 30 mm. This creates a usable travel window of 140 to 170 mm, which can be fine-tuned during commissioning without adding external stops.
