About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-40
The AirTAC SAIJ63X110-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 40 mm. This creates a usable stroke window of 70 to 110 mm, letting you dial in the exact retract position at commissioning without swapping the barrel or adding external stops. It delivers a robust 1559 N pull force at 0.5 MPa, making it well-suited for moderate to heavy positioning tasks.
This SKU is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of switches. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for dead-load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-40 Is Used
Changeover Positioning
Quickly reconfigure the retract end-stop for different product lengths on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the exact 70 to 110 mm travel window during machine commissioning to perfect part seating or clamping depth.
Adjustable Ejector
Set variable ejection distances for parts of different sizes directly at the rear stopper screw.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-40 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (offering 982 N pull at 0.5 MPa) is too weak, but an 80 mm bore (2268 N pull) would be physically oversized. The 40 mm adjustment range is ideal for machinery that requires frequent product-size changeovers, allowing operators to reposition the retract end-stop on the fly rather than maintaining an inventory of fixed-stroke SAI cylinders.
When replacing an ISO 15552 cylinder, match these exact specifications: 63 mm bore, 110 mm nominal stroke, 40 mm adjustment range, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 110 mm stroke is relatively short, side-loading is less of a concern than with longer strokes, but always ensure the load is guided to prevent rod binding.
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 SAIJ63AX110-40 FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 1402 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 110 mm nominal stroke by up to 40 mm. This results in a usable travel window of 70 to 110 mm. It is a travel stop, not a lock, and requires live air to hold the load.
