About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-100S
The AirTAC SAIJ160X800-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 18095N of thrust at 0.9 MPa. It features a robust 40mm piston rod and a PT tapered port. Because of the 100mm adjustment code, you can fine-tune the effective travel anywhere within a 700-800mm window. This eliminates the need to physically swap cylinders during product changeovers.
This SKU includes an integrated magnet for position sensing with CMSE reed or DMSE electronic switches. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the extruded aluminum barrel integrates sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 700 and 800mm during machine setup to accommodate different material lengths without adding external mechanical stops.
Product Size Changeovers
Quickly reconfigure a heavy-duty conveyor diverter or pusher on the fly using the rear adjuster, avoiding the downtime of physically replacing a fixed-stroke cylinder.
Heavy Assembly Pressing
Leverage the 18095N push force at 0.9 MPa to seat large components, using the 100mm adjustment window to fine-tune the pressing depth accurately.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-100S the Right Cylinder?
Choose this 160mm bore cylinder when an application demands high thrust, such as 14074N at 0.7 MPa, combined with variable end-stop positioning. If you need less force, stepping down to a 125mm bore yields 11045N at 0.9 MPa. The adjustable stroke is ideal for commissioning fine-tunes, whereas a fixed SAI cylinder locks you into one exact travel length. For load-holding without continuous air pressure, you must use an external rod lock or pilot-operated check valve, as the SAIJ adjuster is not a brake.
At 800mm of travel, the 40mm rod and M36x2 thread provide substantial support, but an external guide is highly recommended to prevent side-loading damage over this long unsupported distance. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits FB, CA, CB, and CR mounts.

- ✓ 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 SAIJ160AX800-100S FAQ
The rear adjusting screw acts as a mechanical stopper that shortens the retract stroke. For this model, you can trim the nominal 800mm stroke back by up to 100mm, giving a usable travel window of 700-800mm. It only sets the end position and does not lock the load.
At 0.5 MPa, the push force is 10053N and the pull force is 9425N. At the maximum operating pressure of 1.0 MPa, the push force reaches 2050 kgf. The cylinder operates at speeds between 30-500 mm/s.
