About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-10
The AirTAC SAIJ160X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 640-650mm usable travel window, allowing you to fine-tune the retract end-position by up to 10mm during commissioning without adding external stops. Belonging to a heavy-force class, it delivers 18095N of push force at 0.9 MPa, making it suitable for demanding industrial automation.
This model features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and uses PT tapered port threads (G3/4) for secure pneumatic sealing. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific SKU is supplied without a magnet. The rear adjuster acts purely as a travel stop to set deceleration and end-position; it is not a locking device and will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-10 Is Used
Heavy Press Tuning
Dial in the exact 640-650mm retract position during machine commissioning to accommodate material thickness variations without swapping out the entire actuator.
Product Changeover
Quickly adjust the end-stop on packaging or handling lines when switching to a slightly different pallet or product size, minimizing downtime.
Large Assembly Jigs
Leverage the 18095N push force at 0.9 MPa to move heavy structural components into place, using the rear stop to set precise final positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-10 the Right Cylinder?
Select this 160mm bore cylinder when your application requires substantial thrust—stepping down to a 125mm bore yields 11045N of push force at 0.9 MPa, while this SAIJ160X650-10 provides 18095N for high-inertia loads. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering a distinct advantage over a fixed-stroke SAI cylinder. To match this ISO 15552 footprint for replacement, specify: 160mm bore, 650mm stroke, 10mm adjustment, PT G3/4 port, and no magnet. Because the 650mm stroke is long and unsupported, an external guide rail is strongly recommended to prevent excessive rod side-loading and premature seal wear.
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 SAIJ160 Adjustable Cylinder SAIJ160AX650-10 FAQ
At an operating pressure of 0.9 MPa, this 160mm bore cylinder generates 18095N of push force and 9425N of pull force. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 650mm stroke by up to 10mm, creating a 640-650mm travel window. It functions as a mechanical stop to fine-tune the end position and does not lock or hold the load without continuous air pressure.
