About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-40S
The AirTAC SAIJ100X175-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 175mm nominal stroke by up to 40mm. This creates a 135-175mm usable travel window, providing precise end-position tuning at commissioning without swapping the hardware or adding external stops. It delivers robust thrust, pushing 3927N and pulling 3681N at 0.5 MPa.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel carries sensor grooves on both sides, and the G1/2 port handles the required air volume for this high-force size.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-40S Is Used
Product Size Changeover
Dial in the 135-175mm travel window during format resets on packaging lines to accommodate different carton sizes without changing cylinders.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to hit exact positioning targets, avoiding the need for machined external spacers.
Heavy-Duty Forming
Leverage the 3927N push force at 0.5MPa for pressing and clamping tasks while retaining the flexibility to adjust the stroke end-point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-40S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (2513N push at 0.5MPa) is insufficient or a 125mm bore (6136N push) is oversized for your frame. The adjustable 135-175mm travel is ideal for product-size changeovers on a line, letting you fine-tune the retract stop on the fly instead of machining custom spacers. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
When replacing an ISO 15552 cylinder, match the 100mm bore, 175mm stroke, 40mm adjustment, PT port thread, and -S magnet. The rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither holds the load without live air. For load-holding without continuous pressure, use an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders. With a 175mm stroke, ensure external guides support the load to prevent side-loading on the rod.
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 SAIJ100 Adjustable Cylinder SAIJ100AX175-40S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
A rear screw stopper lets you trim the 175mm nominal stroke back by up to 40mm, creating a 135-175mm usable travel window. This adjuster sets the end position but does not lock the load without live air pressure.
