About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX30-30
The AirTAC SAIJ63X30-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 1559 N of push force at 0.5 MPa and features a 20 mm piston rod with an M16x1.5 thread. Because the nominal stroke is 30 mm and the adjustment range is 30 mm, you can dial the effective travel all the way down to zero, giving you a 0-30 mm usable window for precise end-position tuning during commissioning.
This SKU features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic solid-state switches. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard variants.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX30-30 Is Used
Short-Stroke Position Tuning
Dial in the exact end-stop for a short 0-30 mm clamping motion during machine commissioning without swapping cylinders.
Product Changeover Setup
Quickly adjust the retract position on a packaging line when product sizes change, using the rear stopper screw.
Variable End-Stop Machining
Set precise retraction depths for machining heads where the final contact position must be dialed in on-site.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX30-30 the Right Cylinder?
Choose this 63 mm bore adjustable-stroke model when you need the 1559 N thrust class at 0.5 MPa but require exact end-position control without adding external stops. If your application needs less force, the 50 mm bore offers 982 N push force; if you need more, the 80 mm bore provides 2513 N. The rear adjuster acts purely as a mechanical stop to fine-tune the 0-30 mm travel window, meaning it does not lock or hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series. To replace an ISO 15552 cylinder, match the 63 mm bore, 30 mm stroke, PT port thread, and the required mounting accessory.
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 SAIJ63AX30-30 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. It can deliver up to 318 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 30 mm nominal stroke by up to 30 mm, providing a usable travel window of 0 to 30 mm. It decelerates the travel end but does not lock the load without live air.
