About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX135-100S
The AirTAC SAIJ63X135-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 63 mm bore generating 1559 N of push force at 0.5 MPa and a PT G3/8 port. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches. With a 135 mm nominal stroke and a 100 mm adjustment range, you can dial the effective travel down to a 35 mm minimum without swapping hardware.
This wide 35-135 mm adjustable window is perfect for equipment requiring frequent product size changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance. The rear adjuster acts purely as a mechanical stop to set the retract end position, while the standard variable air cushion handles deceleration.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX135-100S Is Used
Product Size Changeovers
Leverage the massive 35-135 mm travel window to rapidly reconfigure line spacing for different product dimensions without changing the cylinder.
Commissioning End-Stop Tuning
Fine-tune the exact retract position during machine setup using the rear screw, avoiding the need to machine custom spacers or swap cylinders.
Adjustable Ejector Stroke
Dial the ejection distance to match part sizes precisely, using the SUS420J2 stainless rod to handle minor environmental exposure.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX135-100S the Right Cylinder?
Choose this 63 mm bore when your application requires approximately 1559 N push force at 0.5 MPa; step down to a 50 mm bore (982 N) for lighter loads, or up to an 80 mm bore (2513 N) for heavier duty. The 100 mm adjustment range allows extreme flexibility during commissioning, letting you fine-tune the retract end position across a 35 to 135 mm travel window without adding external stops. For fixed-position tasks without changeover needs, a standard SAI cylinder is simpler.
Because the nominal stroke is 135 mm, side-load risks are moderate, but always ensure proper external guiding for optimal seal life. Remember that the rear adjuster is a travel stop, not a locking device; this SAIJ cylinder cannot hold a load without live air. For dead-end load holding, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and uses the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ63AX135-100S FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke from its 135 mm nominal length down to 35 mm. It acts as a physical stop for the retract end position, giving you a 100 mm tuning window to accommodate various product sizes without changing the cylinder.
At 0.5 MPa operating pressure, the 63 mm bore provides 1559 N of push force and 1402 N of pull force. The included -S magnet works seamlessly with AirTAC CMSE reed switches and DMSE electronic solid-state sensors for precise position detection.
