About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-40S
The AirTAC SAIJ160X75-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, enabling you to fine-tune the effective travel window down to 35-75 mm from the 75 mm nominal stroke. It delivers robust thrust, providing 10053 N of push force and 9425 N of pull force at 0.5 MPa. This makes it a powerful choice for heavy-duty positioning tasks.
Equipped with a SUS420J2 stainless steel rod (option A) and a built-in magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via PT tapered ports. The rear adjuster acts purely as a mechanical stop to set the end position, meaning it cannot hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-40S Is Used
Press Stroke Calibration
Dial in the exact 35-75 mm travel window during machine commissioning to accommodate varying material thicknesses without external stops.
Heavy-Duty Changeover
Rapidly adjust the end-position stop on a production line when switching between different product sizes, saving setup time.
Variable Positioning
Set precise retract limits for heavy clamping or pressing tasks where a fixed stroke cylinder would require manual shimming.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-40S the Right Cylinder?
Selecting this 160 mm bore model is ideal when your application requires high force in a compact footprint, as stepping down to a 125 mm bore yields only 6136 N push force at 0.5 MPa. The adjustable stroke is highly beneficial for machine setup and product changeover, allowing you to dial in the exact end-stop without swapping cylinders or adding external stops. If your process demands true load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster functions solely as a travel stop.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 75 mm stroke, up to 40 mm adjustment range, PT port threads, and the -S magnet requirement. The mounting options available are a subset of the standard line: Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR mounts.
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 SAIJ160 Adjustable Cylinder SAIJ160AX75-40S FAQ
This 160 mm bore cylinder provides a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 75 mm nominal stroke by up to 40 mm. This creates a usable travel window of 35-75 mm for fine-tuning the end position at commissioning.
