About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-100S
The AirTAC SAIJ63X100-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 0-100 mm from its 100 mm nominal stroke. Delivering 1559 N of push force and 1402 N of pull force at 0.5 MPa, it handles mid-range actuation with precision. The integrated -S magnet enables position sensing with CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves.
This model features a SUS420J2 stainless steel rod for superior corrosion resistance and PT tapered port threads for a tight pneumatic seal. The rear adjustment screw acts purely as a mechanical stop for end-position tuning at commissioning; it does not lock or hold the load without live air pressure. For applications requiring true load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-100S Is Used
Machine Changeover
Dial in the exact retract stop during product size changes without physically swapping out the actuator.
Prototyping Setup
Fine-tune the 0-100 mm travel window during commissioning to find the perfect end-position for new tooling.
Variable End-Stop Positioning
Use the rear adjuster screw to set precise retract limits for delicate pressing or forming tasks.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-100S the Right Cylinder?
Choose this 63 mm bore when you need more thrust than the 50 mm SAIJ (982 N push at 0.5 MPa) but want to avoid the bulk of an 80 mm model. The 100 mm adjustment range is ideal for prototyping or product changeover, allowing you to dial in the exact end-stop on the fly without swapping cylinders or adding external stops. If your application requires a fixed end-position without adjustment, the standard SAI series is a simpler alternative.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 100 mm stroke, PT port threads, and -S magnet. The SAIJ mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, omitting FB, CA, CB, and CR. Since the 100 mm stroke is relatively short, side-load stress is minimal, but an external guide is still recommended for heavy lateral 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 SAIJ63AX100-100S 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 of push force.
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 100 mm, giving a usable travel window of 0-100 mm. This stopper only sets the end-position and does not lock the load without air pressure.
