About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-100
The AirTAC SAIJ63X260-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 160-260 mm window. In the 63 mm bore class, it delivers a robust 1559 N pull force at 0.5 MPa and 2182 N at 0.7 MPa, making it well-suited for moderate to heavy actuation tasks. The unit uses a PT tapered port thread and a G3/8 air supply.
This variant features a SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance compared to standard carbon steel. Because the adjustment mechanism acts purely as a mechanical stop at the retract end, it decelerates the travel but will not hold the load without live air pressure. For position holding without continuous air, consider an external pilot-operated check valve or related types like SAIL or BSAI.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-100 Is Used
Machine Setup Calibration
Dial in the exact retract distance within the 160-260 mm window during initial commissioning without adding external stopper blocks.
Product Changeover
Quickly adapt the end-of-stroke position on a packaging line when handling different product sizes, minimizing downtime.
Variable End-Stop Actuation
Use the 100 mm adjustment range to tune the clamping or pressing depth dynamically for multi-stage assembly operations.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX260-100 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your machine setup requires variable end-stops or precise end-position tuning during commissioning without physically swapping components. If your application demands less force, stepping down to a 50 mm bore yields 825 N of pull at 0.5 MPa. For higher force requirements, moving up to an 80 mm bore provides 2268 N of pull at 0.5 MPa. The SAIJ series supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets. With a 260 mm stroke, the 20 mm rod diameter handles standard loads well, though long unsupported strokes still benefit from an external guide to manage side-load.

- ✓ 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 SAIJ63AX260-100 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 260 mm nominal length down to 160 mm. This provides a 100 mm tuning window for precise end-position calibration.
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
