About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-30S
The AirTAC SAIJ63X230-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 230 mm stroke by up to 30 mm. This creates a precise 200-230 mm usable travel window, perfect for fine-tuning end positions at commissioning without adding external stops. Belonging to the 63 mm bore class, it delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa.
This specific SKU ships with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a magnet (-S) for position sensing. It features PT tapered ports sized G3/8 and uses adjustable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-30S Is Used
Machine Changeover
Dial in the exact 200-230 mm end-stop during product size changeovers without physically swapping the cylinder or shimming the head.
Sensor Calibration
The integrated -S magnet works seamlessly with CMSE and DMSE switches to confirm exact positioning within the tuned travel window.
Assembly Clamping
Provides 1559 N of adjustable push force at 0.5 MPa for clamping parts of varying widths on a single pneumatic assembly line.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX230-30S the Right Cylinder?
Choose this 63 mm bore adjustable cylinder when your application requires a 200-230 mm travel window and roughly 1559 N of thrust at 0.5 MPa. If your force requirements are lower, stepping down to a 50 mm bore yields 982 N of push force; if you need more clamping power, an 80 mm bore provides 2513 N. The rear adjuster acts strictly as a mechanical stop to set deceleration and end-of-travel, meaning it will not hold a load without live air pressure. For true load-holding without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock cylinder series instead.
Because the 230 mm stroke approaches the mid-range of standard travel, always verify that your rod end and mounting interface properly support the load. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR options found on some fixed-stroke variants. The 20 mm piston rod diameter and M16x1.5 rod thread handle moderate side loads well, but long unsupported strokes still necessitate an external guide rail to prevent premature wear.
Quick checklist

- ✓ 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 SAIJ63AX230-30S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 318 kgf.
The rear adjusting screw allows you to shorten the effective stroke from the nominal 230 mm by up to 30 mm, creating a 200-230 mm travel window. This stopper only sets the end position and deceleration; it does not lock the load without live air pressure.
