About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-10S
The AirTAC SAIJ160X70-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5MPa. It features a SUS420J2 stainless steel rod and a built-in magnet for position sensing. With a nominal 70mm stroke and a 10mm adjustment range, it provides an exact 60-70mm usable travel window for fine-tuning end positions at commissioning.
This extruded aluminum barrel design includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear stopper screw allows you to dial in the retract position without adding external stops, while the G3/4 PT port and 50mm cushion ensure robust pneumatic performance for heavy loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-10S Is Used
Heavy Press Fit Tuning
Dial in the exact 60-70mm insertion depth for heavy press fits during machine setup, ensuring precise positioning without external stopper blocks.
Product Size Changeover
Quickly adjust the retract end-stop to accommodate varying product sizes on a high-thrust assembly line without changing the cylinder.
End-Position Calibration
Fine-tune the final resting position of heavy tooling within the 10mm adjustment window during commissioning to perfect the operational stroke.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-10S the Right Cylinder?
Choose this 160mm bore when you need substantially more thrust than the 125mm option (6136N at 0.5MPa) but want to avoid the massive 3204kgf output of the 200mm series. The adjustable 60-70mm window is ideal for applications requiring precise end-position tuning during product changeovers, saving the cost of swapping a fixed-stroke SAI cylinder. For holding loads without live air pressure, note that this rear adjuster acts only as a travel stop, not a lock; you would need a SAIL or BSAI cylinder for secure load holding.
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 SAIJ160AX70-10S FAQ
At 0.5MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach up to 18095N push force at 0.9MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm. This creates a 60-70mm usable travel window, letting you fine-tune the end position during commissioning without swapping the cylinder.
