About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX175-30S
The AirTAC SAIJ63X175-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the 175 mm nominal travel to a precise 145-175 mm window during commissioning. It delivers 2182 N of push force at 0.7 MPa, placing it in a robust mid-range force class for industrial automation. The barrel is extruded aluminum, not a tie-rod design, ensuring a rigid structure with sensor grooves on both sides.
This specific SKU features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnet (-S), it directly supports position sensing using AirTAC CMSE reed switches or DMSE solid-state electronic sensors. The PT tapered port threads (G3/8) provide a tight, reliable pneumatic connection.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX175-30S Is Used
Variable End-Stop Tuning
Dial in the exact 145 to 175 mm retraction point during machine setup to accommodate varying material lengths without physical modifications.
Product Changeover
Quickly adjust the rear stopper on the fly when switching a packaging line to a different carton size, saving downtime on the factory floor.
Position Sensing
Leverage the integrated magnet with DMSE solid-state sensors to confirm end-of-stroke positions in high-vibration manufacturing environments.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX175-30S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore falls short on power (delivering only 1374 N push at 0.7 MPa) but an 80 mm bore is excessive. The 30 mm adjustable stopper is ideal for product changeovers, letting you fine-tune the end-of-stroke position without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and deceleration aid; it does not hold the load without live air. For fail-safe load holding, consider the SAIL (pneumatic lock) or BSAI (clamp-lock) series instead.
To match this ISO 15552 cylinder for a direct replacement, verify the 63 mm bore, 175 mm stroke, 30 mm adjustment range, PT G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on some other series.

- ✓ 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 SAIJ63AX175-30S FAQ
At an operating pressure of 0.7 MPa, this 63 mm bore cylinder provides a push force of 2182 N and a pull force of 1402 N. It can deliver up to 2805 N push force at its maximum rated pressure of 1.0 MPa.
The external rear adjuster screw lets you shorten the effective stroke by up to 30 mm from the nominal 175 mm, creating a usable travel window of 145 to 175 mm. This allows precise end-position tuning without replacing the cylinder.
