About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-10
The AirTAC SAIJ63X160-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 150 to 160 mm, allowing you to dial in the retract end-position precisely at commissioning without adding external stops. Equipped with a 20 mm carbon steel rod and M16x1.5 thread, it delivers 1559 N of pull force at 0.5 MPa.
This SKU features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop—it does not hold the load without live air pressure. Air cushions at both ends handle end-of-stroke deceleration.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-10 Is Used
End-Position Tuning
Fine-tune the retract stroke within a 150-160 mm window during commissioning to perfect product placement without changing hardware.
Machine Changeover
Quickly adapt the cylinder's end-stop when switching product sizes on a packaging line, reducing downtime and avoiding external stopper blocks.
Assembly Pressing
Utilize the 2182 N push force at 0.7 MPa for pressing operations, using the rear screw to set precise depth limits for delicate components.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-10 the Right Cylinder?
Choose this 63 mm bore when your application requires the 1559 N pull force at 0.5 MPa (or 2182 N push at 0.7 MPa). If you need less force, step down to the 50 mm bore which provides 825 N of pull force. The 10 mm adjustable stroke is ideal for machine setups requiring a variable end-stop for product changeovers rather than a fixed-stroke SAI cylinder. Because the stroke is 160 mm, side-loading is moderate, but long unsupported strokes still require an external guide. To replace an ISO 15552 cylinder, match the 63 mm bore, 160 mm stroke, 10 mm adjustment, PT G3/8 port, and standard mounting (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that a plain SAIJ does not hold position without live air; for load-holding, consider SAIL or BSAI.
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 SAIJ63AX160-10 FAQ
At 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 lets you shorten the nominal 160 mm stroke by up to 10 mm, creating a 150 to 160 mm usable travel window. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
