About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-100
The AirTAC SAIJ100X180-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a substantial 100 mm rear stroke adjuster. This configuration creates a wide usable travel window from 80 mm to 180 mm, allowing you to dial in the exact retract end-position during commissioning without swapping out the barrel or adding external stops. It delivers a robust 7068 N of push force at 0.9 MPa.
Equipped with a SUS304 stainless steel rod (option B) and PT tapered port threads, this unit is built for durability and high side-load resilience. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE electronic solid-state switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-100 Is Used
Machine Changeover
Dial in the retract position by up to 100 mm when switching product sizes on a packaging line, eliminating the need to physically swap cylinders for different formats.
Variable End-Stop Tuning
Fine-tune the 80 to 180 mm travel window during commissioning to perfectly time the stroke endpoint without adding external mechanical stops to the fixture.
Heavy Forming Press
Leverage the 7068 N push force at 0.9 MPa for pressing or forming operations, using the wide adjustment range to set precise material engagement depths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-100 the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust (7068 N push at 0.9 MPa) alongside extreme stroke flexibility. If your application requires less force, stepping down to an 80 mm bore yields 4523 N, which may be sufficient for lighter loads. The defining advantage of this SAIJ model is its 100 mm adjustment range, making it ideal for product-size changeovers on a single machine. Unlike a fixed-stroke SAI cylinder, this rear adjuster screw lets you fine-tune the travel end without mechanical modifications.
Because the nominal stroke is 180 mm, an external guide is recommended to manage side loads on the M20x1.5 rod thread. Remember that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL pneumatic lock, the BSAI clamp-lock, or an external rod lock. To replace an ISO 15552 cylinder, verify the 100 mm bore, 180 mm stroke, 100 mm adjustment, PT port, and your required mounting option.

- ✓ 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 SAIJ100BX180-100 FAQ
At a 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 3681 N of pull force. It can deliver a maximum push force of 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke from the nominal 180 mm down to as little as 80 mm. This stop only sets the travel end and does not lock the load without live air pressure.
