About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-30S
The AirTAC SAIJ63X165-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 165 mm stroke that can be fine-tuned down by up to 30 mm, giving you a precise 135-165 mm usable travel window during commissioning. Delivering 1559 N of push force at 0.5 MPa, it fits perfectly into mid-range pneumatic setups.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and fluid is supplied via PT G3/8 tapered ports.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-30S Is Used
Product Changeovers
Quickly adapt the 135-165 mm travel window on packaging lines when switching to different carton sizes without changing the cylinder.
End-Position Tuning
Fine-tune the exact retract distance during machine commissioning to prevent over-travel and ensure precise mechanical indexing.
Sensor-Driven Automation
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end-of-stroke position in automated assembly cells.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX165-30S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is underpowered, but an 80 mm bore (2513 N push) is physically oversized. The adjustable 135-165 mm window is ideal for product changeovers, letting you dial in the exact retract end-position without swapping cylinders or adding external stops. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
To match this exact configuration for an ISO 15552 replacement, specify: 63 mm bore, 165 mm stroke, 30 mm adjustment, PT G3/8 ports, a SUS420J2 rod, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 165 mm stroke is moderate, side-load stress is minimal, but always guide the load externally for optimal M16x1.5 rod life.
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 SAIJ63AX165-30S 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, allowing you to shorten the effective stroke from its 165 mm nominal length down to 135 mm. It sets the travel end but does not lock the load without continuous air pressure.
