About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-100S
The AirTAC SAIJ160X700-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It features a 700 mm nominal stroke that can be dialed back by up to 100 mm, creating a precise 600-700 mm usable travel window for exact end-position tuning during commissioning. At 0.7 MPa, it generates 14074 N of push force and 18095 N at 0.9 MPa.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a -S magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-100S Is Used
Heavy Press Tuning
Fine-tune the 600-700 mm travel window on large metal forming presses to accommodate varying material thicknesses without mechanical retooling.
Pallet Changeover
Adjust the rear stopper during production line size changes to set exact pusher distances for different pallet dimensions on the fly.
Large Fixture Setup
Dial in the exact clamping end-position during initial machine commissioning, leveraging the 100 mm trim range to perfect heavy fixture alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-100S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 3518 N push at 0.5 MPa) lacks the force for heavy payloads, but a 200 mm bore would be excessive. The 100 mm adjustment range is ideal for product changeovers on large equipment, allowing you to shift the end-stop without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder is insufficient; you should specify an SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
Because the 700 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on the piston. As a dimensionally interchangeable ISO 15552 cylinder, it mounts via Basic, FA, LB, TC, FTC, TCM1, or TCM2 accessories (omitting FB/CA/CB/CR). It uses PT threaded ports sized G3/4 and operates at speeds of 30-500 mm/s.

- ✓ 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 SAIJ160BX700-100S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster screw allows you to shorten the 700 mm nominal stroke by up to 100 mm, providing a usable travel window of 600 to 700 mm. It functions as a mechanical stop and does not lock the load without live air.
