About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-40S
The AirTAC SAIJ63X220-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 180-220 mm usable travel window. Operating at 0.5 MPa, it delivers 1559 N of pull force and 2182 N at 0.7 MPa. The integrated -S magnet enables position detection with CMSE reed or DMSE electronic sensors.
This unit uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear screw acts purely as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-40S Is Used
Product Changeover
Quickly reconfigure the 180-220 mm travel window on packaging lines when handling different carton sizes without swapping the cylinder.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to achieve precise mechanical alignment using the rear adjustment screw.
Assembly Stations
Provide adjustable end positions for pressing or seating components, allowing operators to dial in the perfect 63 mm bore force.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-40S the Right Cylinder?
Choose this adjustable model over a fixed SAI when you need to dial in the exact end-of-stroke position during product changeovers without adding external stops. If your application requires less force, stepping down to a 50 mm bore yields 825 N of pull force at 0.5 MPa. For higher thrust, an 80 mm bore provides 2268 N.
Because the 220 mm stroke exceeds 300 mm? No, but for any long stroke, ensure external guiding to prevent side-loading damage to the M16x1.5 rod thread. To hold a load securely without continuous air, select a SAIL or BSAI cylinder instead of relying on the adjuster. Ensure your ISO 15552 replacement matches the 63 mm bore, 220 mm stroke, 40 mm adjustment, PT ports, and -S magnet.

- ✓ 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 SAIJ63AX220-40S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 180 to 220 mm. It functions as a mechanical stop and does not hold the load without live air pressure.
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At 0.7 MPa, the push force increases to 2182 N.
