About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-40S
The AirTAC SAIJ63X130-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 90 to 130 mm. Delivering a push force of 1559 N at 0.5 MPa, it bridges the gap between the 50 mm bore class and larger 80 mm units. The integrated -S magnet enables position feedback via CMSE reed or DMSE electronic solid-state sensors.
This variant is built with an SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads. The external rear stopper sets the retract end-position during commissioning without requiring cylinder swaps or external stops. It is a travel stop only, so an external rod lock or SAIL cylinder is required to hold loads without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-40S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 90 to 130 mm during machine setup to accommodate different material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the stroke window up to 40 mm on a packaging conveyor to handle varying carton sizes on the fly, reducing line downtime.
Sensor-Driven Positioning
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted end-position in automated assembly and clamping fixtures.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-40S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks the thrust for your clamping or lifting task, but an 80 mm bore (2513 N) would be physical overkill. The 40 mm adjustment range is ideal for product changeovers on a packaging line, allowing you to shift the end-stop by up to 40 mm on the fly instead of repositioning fixed hardware.
As a dimensionally interchangeable ISO 15552 cylinder, match your replacement by confirming the 63 mm bore, 130 mm nominal stroke, PT port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. The 20 mm rod diameter and M16x1.5 thread handle moderate side loads, but for this 130 mm stroke an external guide is still recommended for heavy radial loads.
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 SAIJ63AX130-40S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push thrust and 1402 N of pull thrust. At the maximum 1.0 MPa pressure, it delivers up to 318 kgf.
The rear adjuster acts as a mechanical stop that trims the nominal 130 mm stroke back by up to 40 mm, creating a usable travel window of 90 to 130 mm. It only sets the end-position and does not lock or hold the load without live air pressure.
