About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-40S
The AirTAC SAIJ63X110-40-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you fine-tune the retract end-position during commissioning. It provides a usable travel window of 70-110 mm from its 110 mm nominal stroke. Delivering 1559 N of push force at 0.5 MPa, it suits mid-range tasks requiring exact end-stop tuning.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-40S Is Used
Product Changeover
Dial in the 70-110 mm travel window during line changeovers to accommodate different package sizes without physically swapping the actuator.
Commissioning Calibration
Fine-tune the retract end-position to perfect machine timing during setup, avoiding the need to bolt on external mechanical stops.
Assembly Positioning
Provides 1559 N of thrust at 0.5 MPa to push parts into exact fixtures, using the rear stopper to dial in the precise touch point.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-40S the Right Cylinder?
Choose this 63 mm bore when your application requires around 1559 N push force at 0.5 MPa, stepping up from a 50 mm bore (982 N) or down from an 80 mm bore (2513 N). An adjustable stroke is ideal for product changeovers where the exact end-of-stroke varies, saving you from swapping cylinders or adding external stops. Unlike a fixed-stroke SAI, this model trims travel mechanically.
For ISO 15552 replacement matching, specify: 63 mm bore, 110 mm stroke, 40 mm adjustment, G3/8 port, PT thread, and a magnet for sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider SAIL or BSAI. The 20 mm rod and M16x1.5 thread handle side loads well, but long unsupported strokes still need an external guide.
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 SAIJ63AX110-40S 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 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 70 to 110 mm. It sets the end-position but does not lock or hold the load without continuous air pressure.
