About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-40
The AirTAC SAIJ63X230-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 2182N of push force at 0.7MPa, making it well-suited for medium-duty handling. The built-in rear stopper allows you to fine-tune the effective travel window anywhere between 190 and 230mm during machine commissioning without swapping out the unit.
This model features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic switches if position feedback is added later. It supports a standard mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-40 Is Used
Machine Changeover
Dial in the 40mm adjustment window to quickly adapt end positions when switching product sizes on a packaging line.
Assembly Positioning
Achieve precise end-stop tuning at commissioning without adding external physical stops to the machine frame.
Medium-Duty Handling
Leverage the 2182N push force at 0.7MPa for robust clamping and pushing tasks in automated manufacturing cells.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-40 the Right Cylinder?
Choose this 63mm bore when a 50mm bore falls short—offering only 1374N push at 0.7MPa—and before stepping up to the heavier 80mm bore that provides 3518N. The 40mm adjustment range is ideal for product changeovers where the exact end-of-stroke position varies by a few centimeters. Instead of machining external stops, you simply dial in the new position via the rear screw.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. If your application requires fail-safe load holding, consider the SAIL pneumatic lock series instead. Because the total stroke is 230mm, ensure external guidance is used if the load imposes significant lateral stress on the M16x1.5 rod thread.
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 SAIJ63AX230-40 FAQ
At an operating pressure of 0.7MPa, this 63mm bore cylinder provides a push force of 2182N and a pull force of 1402N. It can reach a maximum push force of 2805N at 0.9MPa.
The rear adjuster screw allows you to shorten the nominal 230mm stroke by up to 40mm, creating a usable travel window of 190 to 230mm. This stopper only sets the end position and does not lock the load without air pressure.
