About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-10S
The AirTAC SAIJ63X170-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2182N push force at 0.7 MPa and provides a usable travel window of 160 to 170 mm. This built-in adjustability allows you to fine-tune the retract end position during commissioning without adding external stops.
Equipped with a SUS420J2 stainless steel rod (option A) and a magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the unit uses a PT tapered port (G3/8) for pneumatic connections.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-10S Is Used
Machine Setup Calibration
Dial in the exact 160 to 170 mm retract position during commissioning to achieve precise end-of-stroke tuning without swapping hardware.
Product Changeover
Quickly adapt the cylinder's effective travel window on packaging lines when handling different product sizes, reducing downtime.
Variable End-Stop Positioning
Use the 10mm rear adjustment screw to set variable end stops for delicate pressing or indexing tasks requiring fine-tuned travel limits.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-10S the Right Cylinder?
Choose this 63mm bore when your application requires the 1559N pull force at 0.5 MPa, bridging the gap between the lighter 50mm bore (982N push) and the heavier 80mm bore (2513N push). An adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, whereas a fixed-stroke SAI cylinder is sufficient for static repeatable positions. Remember that the rear adjuster functions only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. This ISO 15552 interchangeable cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ63AX170-10S FAQ
At 0.7 MPa operating pressure, this 63mm bore cylinder provides 2182N of push force and 1402N of pull force. It supports a standard operating speed range of 30 to 800 mm/s.
The rear adjuster acts as a travel stop that allows you to mechanically shorten the effective stroke within a 160 to 170 mm usable window. It is not a lock and will not hold the load without continuous air pressure.
