About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-20S
The AirTAC SAIJ63X130-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 1559 N of push force at 0.5 MPa and features a 20 mm adjustment range, yielding a usable travel window of 110 to 130 mm for precise end-position tuning at commissioning.
This variant includes a SUS420J2 stainless steel rod for improved corrosion resistance and a built-in magnet compatible with CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set deceleration and travel limits; it does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-20S Is Used
Machine Changeover
Dial in the exact 110 to 130 mm end-stop during product size changes on a packaging line without physically replacing the actuator.
End-Position Tuning
Fine-tune the retract stroke at commissioning to perfect the seating pressure of a forming tool, using the rear screw rather than external stops.
Sensor-Ready Automation
Leverage the integrated magnet with DMSE solid-state sensors to confirm end-of-stroke positions within the adjusted travel window.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-20S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore falls short on power (982 N push at 0.5 MPa) and a larger 80 mm bore provides unnecessary force (2513 N). The 20 mm adjustable stroke is ideal for setups requiring variable end-stops during product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. To replace this ISO 15552 unit, match the 63 mm bore, 130 mm stroke, 20 mm adjustment, PT G3/8 port, and the -S magnet requirement.
For any stroke of 130 mm, the 20 mm diameter rod and M16x1.5 thread handle moderate side loads, but an external guide is recommended for heavy lateral forces. Remember that the rear stopper cannot hold a load unpowered; for true fail-safe holding, 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 SAIJ63AX130-20S 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 the maximum 1.0 MPa pressure, it delivers up to 318 kgf.
The rear adjuster allows you to shorten the nominal 130 mm stroke by up to 20 mm, creating a usable travel window of 110 to 130 mm. The adjuster acts as a mechanical stop to set the end position and does not function as a lock to hold the load without air pressure.
