About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-100
The AirTAC SAIJ63X180-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 180 mm travel back by up to 100 mm. This creates a wide 80-180 mm usable travel window, letting you dial in the exact retract position at commissioning without swapping out the barrel or adding external stops. Built with a SUS420J2 stainless steel rod, it delivers a robust 2182 N push force at 0.7 MPa.
The defining trait of this SAIJ variant is its external rear stopper, which acts purely as a travel limit and deceleration point, not a load-holding lock. It retains the standard ISO 15552 mounting interface and uses a PT tapered G3/8 port. For position feedback, you can add a magnet to the standard extruded aluminum barrel to accept CMSE reed or DMSE electronic sensors in the dual-side grooves.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-100 Is Used
Product Changeover
Dial in the retract stroke from 180 mm down to 80 mm to switch between varying package sizes on a single conveyor line without changing hardware.
Machine Setup
Fine-tune the end-of-travel position during initial commissioning to perfectly time the tooling engagement without adding external mechanical stops.
Variable End Stops
Use the wide 100 mm adjustment window to test multiple retraction depths during prototyping before locking in a final fixed position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-100 the Right Cylinder?
Choose this 63 mm bore when an application requires the 1559 N pull force at 0.5 MPa or the 2182 N push at 0.7 MPa, but a fixed SAI stroke cannot accommodate frequent product size changes. The 100 mm adjustment range is ideal for modular tooling that needs rapid end-stop modifications during line changeovers. If you need less force, stepping down to a 50 mm bore yields 1374 N push at 0.7 MPa.
When matching this cylinder for ISO 15552 replacement, verify the 180 mm stroke, 100 mm adjuster, G3/8 PT port, and the required mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the rear adjuster only stops travel and the air cushions manage deceleration, this cylinder cannot hold a load without live air pressure. For fail-safe load holding, specify an external rod lock or transition to an AirTAC SAIL or BSAI series.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX180-100 FAQ
At 0.7 MPa operating pressure, this 63 mm bore double-acting cylinder generates 2182 N of push force and 1402 N of pull force.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 100 mm, providing an 80-180 mm usable travel window. It acts as a mechanical stop and does not hold the load without continuous air pressure.
