About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X260-30S
The AirTAC SAIJ63X260-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 260 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 230-260 mm usable travel window. Delivering 1559 N of pull force at 0.5 MPa, it fits perfectly into mid-range automation tasks.
This variant includes a magnetic piston for position detection and uses standard carbon steel rod material. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches exactly where needed. Adjustment is handled mechanically at the rear, meaning you can dial in the end position during commissioning without adding external stops.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X260-30S Is Used
Product Changeover
Quickly dial in the 230-260 mm stroke window during format changeovers on packaging lines without physically replacing the cylinder.
End-Position Tuning
Fine-tune the retract stroke end during machine commissioning to perfectly seat parts, avoiding the need for external mechanical stops.
Assembly Pressing
Leverage the 1559 N pull force to press or seat components, using the rear screw to precisely limit the travel distance.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X260-30S the Right Cylinder?
Choose this 63 mm bore when you need more force than a 50 mm cylinder (which provides 825 N pull at 0.5 MPa) but want to avoid the larger footprint of an 80 mm option. The adjustable 230-260 mm window is ideal for machine setups requiring product changeovers, letting you reposition the end-of-stroke mechanically rather than swapping out a fixed-length SAI cylinder. Fluid must be 40 um filtered air, operating between 0.15 and 1.0 MPa.
Because the stroke is 260 mm, ensure adequate external guiding to prevent excessive side loading on the 20 mm carbon steel rod. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. This SKU uses a PT tapered port thread and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ63X260-30S FAQ
At 0.5 MPa it provides 1559 N of pull force and 2182 N of push force. At the maximum 1.0 MPa operating pressure, it delivers up to 318 kgf.
A rear screw stopper lets you shorten the 260 mm nominal stroke by up to 30 mm, providing a usable travel window of 230 to 260 mm. It acts as a physical stop and does not lock the load without air pressure.
