About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX145-10
The AirTAC SAIJ63X145-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 135-145 mm usable travel window. Delivering 1559 N push thrust at 0.5 MPa, it handles robust actuation while allowing precise end-position tuning without external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features a PT tapered port thread. The rear adjuster acts strictly as a travel stop to dial in the retract position, while the standard air cushion manages end-of-stroke deceleration.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX145-10 Is Used
End-Stop Tuning
Dial in the exact 135-145 mm retract position during machine commissioning without swapping cylinders or adding external shims.
Product Changeover
Quickly adjust the stroke by up to 10 mm on automated lines handling slight variations in packaging or workpiece sizes.
Corrosive Actuation
Leverage the SUS420J2 stainless steel rod for reliable thrust in environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX145-10 the Right Cylinder?
Select this 63 mm bore when you need 1559 N of push force at 0.5 MPa and a mechanism to fine-tune the retract end-stop during machine commissioning. If your application requires less force, the 50 mm bore offers 982 N; for heavier loads, the 80 mm bore provides 2513 N. The 10 mm adjustment range is ideal for minor product changeovers where a fixed-stroke SAI cylinder would require mechanical shims.
For ISO 15552 dimensional interchangeability, match the 63 mm bore, 145 mm stroke, PT G3/8 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster is a stop, not a lock; the SAIJ cannot hold a load without live air pressure. For fail-safe load holding, consider the 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 SAIJ63AX145-10 FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push thrust and 1402 N of pull thrust. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 145 mm nominal stroke by up to 10 mm, creating a 135-145 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
