About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-40S
The AirTAC SAIJ160X70-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. Its 70mm nominal stroke can be dialed back by up to 40mm, creating a precise 30-70mm usable travel window for fine-tuning end positions during commissioning. This eliminates the need to swap cylinders or bolt on external stops when aligning heavy loads.
This SKU features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-40S Is Used
Heavy Press Tuning
Dial in the exact 30-70mm travel window during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the rear stopper on a packaging line to handle different product sizes, reducing downtime between production runs.
Assembly Positioning
Fine-tune the end position of heavy components on an assembly line, relying on the 10053N push force at 0.5 MPa for robust actuation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-40S the Right Cylinder?
Choose this 160mm bore when an 80mm cylinder's 3518N push force at 0.5 MPa is insufficient for heavy positioning tasks. The adjustable 30-70mm travel window is ideal for product-size changeovers on a line, whereas a fixed-stroke SAI requires exact upfront calculations. To match this cylinder for an ISO 15552 replacement, specify the 160mm bore, 70mm stroke, PT tapered ports, the -S magnet, and the SUS420J2 rod.
Because the stroke is short, side-loading is minimal, but the 40mm rod and M36x2 thread handle high axial stress well. If your application requires holding a load without continuous air pressure, the SAIJ adjuster cannot act as a brake; instead, select an AirTAC SAIL or BSAI locking cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160AX70-40S FAQ
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 70mm nominal stroke by up to 40mm, providing a usable travel range of 30-70mm. The adjuster acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
