About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-75
The AirTAC SAIJ63X290-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 1559N push force at 0.5MPa and provides a usable travel window of 215-290mm, letting you shorten the 290mm nominal stroke by up to 75mm during machine setup.
This model uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, while the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-75 Is Used
Product Changeovers
Dial in the retract position by up to 75mm to accommodate different product lengths on the same line without mechanical rebuilds.
End-Position Tuning
Hit exact 215 to 290mm travel windows during commissioning by trimming the stroke at the rear stopper rather than shimming the tooling.
Corrosive Assembly Lines
Leverage the SUS420J2 stainless steel rod option for reliable actuation in humid or mildly corrosive manufacturing environments.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX290-75 the Right Cylinder?
Choose this 63mm bore when a 50mm bore's 982N push at 0.5MPa is insufficient, or step down if 40mm's 628N is enough. The 75mm adjuster is ideal for product changeovers, allowing you to fine-tune the retract end-position without swapping cylinders or adding external stops. Since the rear adjuster is a travel stop and not a lock, use a SAIL or BSAI cylinder if you need fail-safe load holding without live air. For this 290mm stroke, ensure proper external guiding to handle side loads. Match your exact ISO 15552 replacement by confirming the 63mm bore, 290mm stroke, 75mm adjustment, PT G3/8 port, and standard mounting.
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 SAIJ63AX290-75 FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel from the 290mm nominal stroke down to 215mm. It only sets the end position and does not lock the load without live air pressure.
