About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-30
The AirTAC SAIJ160X70-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 40 to 70 mm. Equipped with a robust 40 mm SUS420J2 stainless steel rod and PT tapered ports, it generates 10053 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This adjustable-stroke design allows operators to dial in the exact retract end-position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting hardware utilizes the reduced SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-30 Is Used
Heavy Press Tuning
Dial in the exact 40 to 70 mm retract distance during heavy press setup, allowing precise end-position tuning without swapping out the entire cylinder.
Product Changeover
Adapt to varying workpiece sizes on the fly by adjusting the rear stopper up to 30 mm, minimizing downtime between production runs.
Heavy Assembly Jigs
Leverage the 10053 N pull force to secure and position large components, using the fine stroke adjustment to perfect the clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-30 the Right Cylinder?
Choose this 160 mm bore when a 125 mm cylinder's 5734 N retract force at 0.5 MPa is insufficient for your load. The adjustable 40-70 mm window is perfect for applications requiring precise end-stop tuning during product changeovers. If you need to hold a load vertically without continuous air pressure, note that this cylinder's rear adjuster acts only as a travel stop; you should instead select a SAIL locking cylinder or an external rod lock.
To replace an ISO 15552 cylinder, match the 160 mm bore, 70 mm nominal stroke, 30 mm adjustment range, PT G3/4 port thread, and desired mounting hardware. Because the stroke is relatively short for this large bore, side-load concerns are minimal, but the heavy 40 mm rod still requires proper alignment to prevent 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 SAIJ160AX70-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 40 to 70 mm, allowing you to fine-tune the end position at commissioning without replacing the cylinder.
