About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-40
The AirTAC SAIJ63X130-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 130 mm nominal travel to a precise 90-130 mm usable window. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation while fine-tuning the retract end position during commissioning. This configuration features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and PT tapered ports.
Because the adjuster functions strictly as a mechanical stop and does not lock the load, continuous air pressure is required to hold position. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if needed. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-40 Is Used
Changeover Calibration
Dial in the exact 90 to 130 mm retract distance when switching between product sizes on a packaging line without changing hardware.
End-Position Trimming
Fine-tune the final retract position during machine setup to perfect tooling alignment, absorbing mechanical tolerance drift.
Variable End Stops
Provide adjustable physical stops for automated clamping stations where the exact material thickness varies between production runs.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-40 the Right Cylinder?
Choose this 63 mm bore when a 50 mm cylinder (825 N pull at 0.5 MPa) lacks the force for your payload, but an 80 mm bore (2268 N pull) is physically oversized. The 40 mm adjustment range is ideal for production lines running mixed product sizes, letting you reset the retract end-stop without swapping the cylinder or adding external stops. For load-holding without live air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on this adjuster.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 130 mm stroke, G3/8 port, and mounting hardware. This SKU uses a SUS420J2 rod and PT ports. Since the stroke is under 300 mm, side-load stress on the M16x1.5 rod thread is manageable, though external guides remain 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 SAIJ63AX130-40 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 1559 N of push force. At the maximum 1.0 MPa pressure, it achieves up to 318 kgf.
The rear adjuster acts as a mechanical stop that shortens the 130 mm nominal stroke. You can trim the effective travel back by up to 40 mm, creating a 90 to 130 mm usable window to fine-tune the end position without external stops.
