About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10
The AirTAC SAIJ63X110-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 110 mm travel that can be dialed back by up to 10 mm, yielding a 100-110 mm usable window for fine-tuning the retract end position during commissioning. Delivering 1559 N of push thrust at 0.5 MPa, it handles robust actuation tasks.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE solid-state switches. It supports a standard speed range of 30-800 mm/s and relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10 Is Used
Machine Setup Tuning
Dial in the exact 100-110 mm retract position during initial commissioning to align stamping or clamping heads without machining custom spacers.
Product Changeover
Quickly adapt the end-stop for different package sizes on a packaging line, using the 10 mm adjustment window to switch profiles rapidly.
Deceleration Testing
Leverage the variable air cushions at both ends alongside the rear stopper to safely dial in the deceleration curve for heavy moving loads.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-10 the Right Cylinder?
Select this 63 mm bore cylinder when your application requires 1559 N push force (or 1402 N pull) at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N. The 10 mm rear adjuster is chosen over a fixed-stroke SAI when you need to trim the retract position without adding external stoppers or swapping cylinders during machine setup. When matching an ISO 15552 replacement, verify the 110 mm stroke, 10 mm adjustment range, PT G3/8 port, and standard mounting interface.
Because the stroke is 110 mm, side-load risks are minimal, but the load should still be guided to prevent rod binding. Remember that the rear adjuster acts only as a mechanical stop and the air cushion provides deceleration; neither will hold the load without live air pressure. For true fail-safe load holding, consider an external pilot-operated check valve or the AirTAC SAIL locking cylinder.
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 SAIJ63AX110-10 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. It can deliver up to 2805 N push force at 0.9 MPa.
A rear screw stopper mechanically limits the piston's retract travel, allowing you to shorten the effective stroke from 110 mm down to 100 mm. This adjuster acts as a travel stop and does not lock the load without continuous air pressure.
