About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-30S
The AirTAC SAIJ63X260-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 230 to 260 mm, letting you dial back the nominal 260 mm stroke by up to 30 mm during commissioning without adding external stops. Delivering 1559 N of push force at 0.5 MPa, it handles robust actuation while maintaining a standard ISO 15552 mounting footprint.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet operates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-30S Is Used
Machine Changeover
Dial in the 230 to 260 mm travel window to accommodate new product lengths on a packaging line without physically swapping the actuator.
End-Position Tuning
Fine-tune the retract stroke by up to 30 mm during setup to compensate for mechanical wear or sensor drift over time.
Assembly Pressing
Leverage the 1559 N push force at 0.5 MPa to seat components, using the adjustable stop to regulate the exact pressing depth.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-30S the Right Cylinder?
Choose this 63 mm bore when 50 mm models fall short—offering 982 N at 0.5 MPa—and before stepping to 80 mm which provides 2513 N. The adjustable stroke is ideal for product changeovers or fine-tuning end positions on the fly, avoiding the need to swap out a fixed-stroke SAI cylinder. Since the stroke is 260 mm, ensure adequate external guiding to prevent excessive side loading on the rod.
For position holding without continuous air pressure, note that the rear adjuster acts only as a travel stop, not a lock. You will need an external rod lock, a pilot-operated check valve, or an AirTAC SAIL/BSAI cylinder for secure load holding. This model uses PT ports and is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ63AX260-30S 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 reach up to 2182 N push at 0.7 MPa.
The rear adjuster screw lets you shorten the nominal 260 mm stroke by up to 30 mm, creating a 230 to 260 mm usable travel window. It acts as a mechanical stop and does not lock the load without live air pressure.
