About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-75S
The AirTAC SAIJ125X160-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel to create a precise 85-160 mm usable window. Delivering 6136 N of push force at 0.5 MPa, it handles heavy-duty positioning with ease. The integrated -S magnet enables position sensing via AirTAC CMSE reed or DMSE electronic switches.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance compared to standard carbon steel. The rear stopper screw lets you fine-tune the retract end-position during commissioning without swapping hardware. Note that this adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-75S Is Used
Variable End-Stop Calibration
Dial in the exact retract position within the 85-160 mm window during machine setup, perfect for accommodating different product heights without changing cylinders.
Product Changeover
Quickly adjust the stroke length on packaging lines when switching between box sizes, using the rear stopper to set new end positions rapidly.
Heavy-Duty Positioning
Leverage the 6136 N push force at 0.5 MPa to move heavy pallets or fixtures, relying on the robust 32 mm rod and M27x2 thread to handle demanding industrial loads.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX160-75S the Right Cylinder?
Choose this 125 mm bore when a 100 mm bore (offering 3927 N push at 0.5 MPa) lacks the necessary thrust, but a 160 mm bore (10053 N) would be excessive. The 75 mm adjustment range is ideal for product changeovers on a packaging line, letting operators set variable end-stops on the fly. For load-holding without continuous air supply, an external pilot-operated check valve or an AirTAC SAIL lock cylinder is required, as the SAIJ adjuster is not a brake.
To match this exact ISO 15552 footprint for a direct replacement, specify: 125 mm bore, 160 mm stroke, 75 mm adjustment, PT tapered port threads, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 160 mm stroke is relatively short for this bore, side-loading risks are minimal, but external guides remain recommended for heavy lateral loads.
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 SAIJ125 Adjustable Cylinder SAIJ125AX160-75S FAQ
At 0.5 MPa operating pressure, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. If higher pressure is available, it can deliver up to 8590 N push at 0.7 MPa.
The rear adjuster screw allows you to mechanically shorten the effective stroke from its nominal 160 mm down to as little as 85 mm. This creates a 75 mm adjustable travel window for fine-tuning the end position without needing external stops.
