About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX145-100S
The AirTAC SAIJ63X145-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 1559N of push force at 0.5 MPa. Its generous 100mm adjustment screw yields a usable travel window of 45-145mm, letting you dial in the exact retract end-position during commissioning without swapping hardware. This bore features a 20mm piston rod, G3/8 port, and 36mm cushion strokes.
Built for position feedback, the -S variant includes a magnet for AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. This specific unit uses a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and ships with PT tapered port threads.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX145-100S Is Used
Product Changeover
Rapidly reconfigure retract depth for different packaging heights using the 45-145mm travel window instead of changing out the entire cylinder assembly.
Commissioning Calibration
Fine-tune the exact end-of-stroke position during machine setup to prevent crashing, relying on the 100mm rear stopper rather than external shims.
Variable End Stops
Handle multiple part sizes on a single machining line by adjusting the stroke down to 45mm, leveraging the 1559N force for consistent clamping.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX145-100S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (982N push at 0.5MPa) lacks thrust but an 80mm bore (2513N) is physically too large. The extreme 100mm adjustability is ideal for machines running multiple product sizes, replacing fixed-stroke SAI cylinders and external stops with a single rear screw. Note that the adjuster is a travel stop, not a lock; the SAIJ63X145-100-S cannot hold a load without live air, so specify SAIL or BSAI variants if true mechanical locking is required.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm: 63mm bore, 145mm nominal stroke, 100mm adjustment, G3/8 PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet. Because the nominal stroke is 145mm, standard mounting is fine, but always ensure the 20mm rod thread is aligned to minimize side-loading on the guide.
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 SAIJ63AX145-100S FAQ
At 0.5 MPa it provides 1559N of push force and 1402N of pull force. If you need more thrust, stepping up to an 80mm bore yields 2513N at the same pressure.
The rear adjuster acts as a stop that lets you mechanically shorten the 145mm stroke down to as little as 45mm. It only sets the travel end and does not lock the load without continuous air pressure.
