About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75S
The AirTAC SAIJ63X130-75-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, alongside an SUS420J2 stainless steel rod. The built-in magnet supports position sensing with CMSE reed or DMSE electronic switches.
This specific SKU provides a 130 mm nominal stroke that can be dialed back by up to 75 mm, yielding a highly versatile 55-130 mm usable travel window. The rear screw mechanism acts purely as an end-position stop for commissioning tuning and does not lock the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75S Is Used
Product Changeover Tuning
Dial in the exact 55-130 mm end-stop during format size changes on a packaging line without adding external mechanical stops.
Variable End-Stop Positioning
Set precise retract positions for multi-stage tooling arrays, using the 75 mm adjustment range to adapt the stroke on the fly.
Commissioning Fine-Tuning
Trim the effective travel window during machine commissioning to perfectly time the 1559 N thrust against varying workpiece heights.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-75S the Right Cylinder?
Choose this adjustable model when an application requires frequent end-position changes across a 55-130 mm window, avoiding the need to physically swap cylinders during product changeovers. If your setup needs less than 1559 N of thrust at 0.5 MPa, step down to the 50 mm bore (982 N); if more force is required, step up to the 80 mm bore (2513 N). To replace an ISO 15552 cylinder, match the 63 mm bore, 130 mm stroke, PT tapered port, and the -S magnet.
Because the 130 mm stroke is under the 300 mm threshold, side-load stress on the 20 mm rod is naturally lower, though external guides remain recommended for heavy lateral loads. Remember that the rear adjuster is a travel stop, not a brake; for dead-load holding without live air, select an AirTAC SAIL or BSAI cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ63AX130-75S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the 130 mm nominal stroke by up to 75 mm, creating a usable travel window of 55 to 130 mm. The adjuster functions as a physical stop and does not lock the load without continuous air pressure.
