About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-10
The AirTAC SAIJ63X230-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to 220 mm from its 230 mm nominal length. Delivering a robust 2182N of push force at 0.7 MPa, it bridges the gap between mid-size and large bore actuators. The SUS420J2 stainless steel rod provides excellent corrosion resistance for demanding environments.
Equipped with a PT tapered G3/8 port, this model operates at speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop for end-position tuning at commissioning and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-10 Is Used
Machine Commissioning
Dial in the exact 220-230 mm end-stop during initial setup to perfect product placement without adding external spacers.
Product Changeover
Quickly adjust the retract position by up to 10 mm when running a slightly shorter part on the same line.
Assembly Pressing
Apply up to 2805N of push force at 0.9 MPa for seating components, using the rear stop to prevent over-travel.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-10 the Right Cylinder?
Select this 63 mm bore when your application requires the 1559N push force at 0.5 MPa, offering a step up from the 50 mm bore (982N) without the bulk of an 80 mm option. The 10 mm adjustment window is ideal for dialing in exact end positions during machine commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. For exact ISO 15552 replacement, match the 63 mm bore, 230 mm stroke, PT G3/8 port, and standard mounting interface. Since the stroke is 230 mm, ensure external guiding if the load imposes significant side loads on the M16x1.5 rod thread. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air, 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 SAIJ63AX230-10 FAQ
At 0.5 MPa it provides 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
A rear external screw stopper lets you shorten the effective travel from 230 mm down to 220 mm. It acts as a mechanical stop to tune the end position and is not a lock, meaning the cylinder requires live air to hold its position.
