About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-100
The AirTAC SAIJ63X130-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the nominal 130 mm travel back by up to 100 mm. This creates a highly flexible 30 to 130 mm usable travel window, letting you dial in the exact retract position at commissioning without swapping out the barrel or adding external stops. In the 63 mm bore class, it delivers 1559 N of push thrust and 1402 N of pull thrust at 0.5 MPa, making it well-suited for medium-force positioning tasks.
This specific SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced resistance to corrosion and surface wear in harsher environments. It uses PT tapered port threads (G3/8) for tight pneumatic sealing, and because no -S magnet option is specified, it relies on mechanical end-position tuning rather than internal magnetic sensing. The extruded aluminum barrel integrates sensor grooves on both sides, while the rear adjuster functions purely as a travel stop to set deceleration and end-positioning, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-100 Is Used
Machine Changeover
Quickly reconfigure the retract distance from 30 mm up to 130 mm via the rear screw during product size transitions on a packaging line.
End-Position Tuning
Fine-tune the exact end-stop at commissioning to absorb mechanical tolerances without machining custom spacer blocks or changing the cylinder.
Variable Stroke Stops
Set distinct retract positions for different operational modes within a single assembly station, leveraging the 100 mm adjustment window.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-100 the Right Cylinder?
Choose this 63 mm bore adjustable-stroke cylinder when your application requires variable end-stops or frequent product changeovers that demand a different retract distance within that 30 to 130 mm range. If your process needs less force, stepping down to a 50 mm bore yields 982 N of push thrust at 0.5 MPa; stepping up to an 80 mm bore provides 2513 N. Because the nominal stroke here is under 300 mm, side-load stress on the 20 mm rod is moderate, though an external guide is still recommended for heavy lateral loads.
Selecting this model gives you the exact ISO 15552 mounting interface dimensions for interchangeability with standard profile cylinders, paired with AirTAC's reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster and air cushions only manage travel ends and deceleration; if you need true load-holding without continuous air pressure, you must integrate an external rod lock or look at the SAIL or BSAI series. To match this exact configuration, specify: 63 mm bore, 130 mm nominal stroke, 100 mm adjustment, PT G3/8 ports, SUS420J2 rod, and no magnet.

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 SAIJ63AX130-100 FAQ
The rear adjuster acts as an external stopper that shortens the effective stroke. For this model, you can trim the nominal 130 mm stroke back by up to 100 mm, providing a usable travel window of 30 to 130 mm. It sets the travel end and deceleration point but does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ63X130-100 provides 1559 N of push thrust and 1402 N of pull thrust. It can reach up to 2805 N of push thrust at its maximum 0.9 MPa operating pressure.
