About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-40S
The AirTAC SAIJ160X90-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 50-90 mm usable travel window from its 90 mm nominal stroke. It delivers 14074 N of push force at 0.7 MPa, making it suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses an SUS420J2 stainless steel rod for superior corrosion resistance and includes a built-in magnet for CMSE reed and DMSE electronic sensors. The rear adjuster acts as a mechanical stop to fine-tune the retract position during commissioning without adding external stops, though it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-40S Is Used
Heavy Press Tuning
Dial in the exact 50-90 mm retract stop during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the end-of-stroke position on automated lines when switching product sizes, using the rear screw to set new dimensions.
Fixture Positioning
Set precise clamping locations on large fixtures, relying on the 14074 N force and fine-tuning the travel to avoid overtravel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-40S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (3518 N push at 0.7 MPa) is insufficient and a 200 mm bore (21991 N push at 0.7 MPa) is excessive. The adjustable 50-90 mm travel window is ideal for product changeovers requiring precise end-position tuning. For load-holding without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is a travel stop, not a brake.
To match this ISO 15552 replacement, specify a 160 mm bore, 90 mm stroke, 40 mm adjustment range, PT tapered ports, SUS420J2 rod material, and a magnet for sensors. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160AX90-40S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 90 mm nominal stroke by up to 40 mm, creating a 50-90 mm usable travel window. This allows precise end-position tuning without external stops, though the screw functions only as a stop and does not hold the load without air pressure.
