About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30S
The AirTAC SAIJ63X130-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the effective travel to a precise 100-130mm window during commissioning. It delivers 1559N of push force and 1402N of pull force at 0.5 MPa, making it a robust choice for medium-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and includes an integrated magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches to verify your adjusted end-stop.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30S Is Used
Machine Changeover
Quickly fine-tune the retract end-position by up to 30mm when switching a packaging line to a different carton size, eliminating the need to physically swap cylinders.
Variable End-Stop Positioning
Dial in the exact 100-130mm travel window during initial commissioning to perfectly time a pressing or feeding motion without mechanical rework.
Corrosion-Resistant Actuation
Leverage the SUS420J2 stainless steel rod and 1559N thrust for reliable automation in environments where standard carbon steel rods risk degradation.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-30S the Right Cylinder?
Select this 63mm bore when a standard fixed-stroke SAI cylinder cannot accommodate machine changeovers or varying product sizes, as the external rear screw lets you trim the stroke by up to 30mm without adding external stops. If your application requires less force, stepping down to a 50mm bore yields 982N of push force at 0.5 MPa; for heavier loads, an 80mm bore provides 2513N. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air—use an external rod lock or SAIL cylinder for fail-safe load holding.
This model is dimensionally interchangeable per ISO 15552 and is configured with PT tapered port threads, a G3/8 air supply port, and a magnet for sensors. It supports a reduced mounting set including 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 SAIJ63AX130-30S FAQ
The rear adjuster screw allows you to mechanically shorten the 130mm nominal stroke by up to 30mm, providing a usable travel window of 100-130mm. This stopper decelerates the travel end but does not lock the load without continuous air pressure.
At a 0.5 MPa operating pressure, the SAIJ63X130-30-S generates 1559N of push force and 1402N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 318 kgf of push force.
