About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-20S
The AirTAC SAIJ63X110-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 90-110 mm for precise end-position tuning. Fitted with a G3/8 port and a 20 mm rod, it delivers 1559 N of pull force at 0.5 MPa, making it suitable for medium-duty handling. The -S designation indicates an integrated magnet for position sensing.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount either CMSE reed or DMSE electronic switches exactly where needed. Unlike a fixed-stroke SAI, this model lets you dial in the retract stop without adding external bumpers.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-20S Is Used
Changeover Calibration
Dial in the 90-110 mm retract stop during machine changeovers to accommodate different product lengths without swapping hardware.
End-Position Trimming
Fine-tune the final resting position of a tooling plate by up to 20 mm at commissioning, eliminating the need for external stopper blocks.
Sensor-Driven Handling
Leverage the integrated magnet with DMSE electronic sensors to confirm mid-stroke or end-stroke positions in automated assembly lines.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-20S the Right Cylinder?
Select this 63 mm bore cylinder when an application requires 1559 N pull force at 0.5 MPa but demands variable end-stops for product changeovers; if you need less force, a 50 mm bore offers 825 N pull. The rear adjuster acts purely as a travel stop to fine-tune the 90-110 mm window, meaning it cannot hold a load without live air—always use a SAIL or BSAI locking cylinder for pneumatic load-holding. To match this ISO 15552 footprint exactly, specify the 63 mm bore, 110 mm stroke, 20 mm adjustment, PT ports, and the -S magnet.
Because the stroke is 110 mm, side-load risks are minimal, but the 20 mm rod thread still requires external guiding if subjected to lateral forces. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ63AX110-20S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 90-110 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, this double-acting cylinder provides 1559 N of pull force and 2182 N of push force at 0.7 MPa.
