About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-20
The AirTAC SAIJ100X180-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 160-180 mm usable travel window, allowing you to dial back the nominal 180 mm stroke by up to 20 mm during commissioning. Delivering 5497 N of push force at 0.7 MPa, it handles heavy loads with precision.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-20 Is Used
Machine Setup & Changeover
Fine-tune the 160-180 mm travel window during product line changeovers to hit exact end positions without mechanical rework.
Variable End-Stop Positioning
Dial in the precise retraction point for tooling adjustments, using the rear screw to trim the stroke by up to 20 mm on the fly.
Heavy-Duty Forming
Leverage the 5497 N push force at 0.7 MPa for pressing or clamping operations that require slight stroke variance per batch.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-20 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (2182 N push at 0.5 MPa) is insufficient, but a 125 mm bore is oversized. The 20 mm adjustment range is ideal for product changeovers, letting you fine-tune the end position without swapping cylinders or adding external stops. For a fixed end position, a standard SAI cylinder suffices.
To replace an ISO 15552 cylinder, match the 100 mm bore, 180 mm stroke, PT port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Since the 180 mm stroke is under 300 mm, side-load stress is moderate, but the 25 mm rod still requires an external guide for heavy lateral loads. For load-holding without air, use a SAIL or BSAI cylinder.
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 SAIJ100AX180-20 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 5497 N of pull force. At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw lets you shorten the effective travel from the 180 mm nominal stroke down to 160 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
