About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-75S
The AirTAC SAIJ100X160-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100 mm bore, a 160 mm nominal stroke, and a built-in stopper that allows you to trim the effective travel back by up to 75 mm, creating a precise 85 to 160 mm usable window. This on-machine tuning lets you dial in exact end positions during commissioning or product changeovers without physically swapping the cylinder or adding external stops.
Delivering 3927 N of push force and 3681 N of pull force at 0.5 MPa, this SUS304 stainless steel rod model is built for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-75S Is Used
Product Changeover Tuning
Quickly adjust the 85-160 mm travel window to accommodate new package sizes on a packaging line without disassembling the cylinder mounting.
End-Position Calibration
Fine-tune the retract stroke end during machine commissioning to ensure precise mechanical alignment without adding external stopper blocks.
Variable Forming Stops
Dial in the exact forming depth on an assembly press by adjusting the rear stopper, leveraging the 3927 N push force at 0.5 MPa.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-75S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) is too weak but a 125 mm bore is physically oversized. The SAIJ100X160-75-S is selected over a fixed SAI when your setup requires variable end-stops or fine-tuning at commissioning. To match this ISO 15552 interchangeable cylinder exactly, specify the 100 mm bore, 160 mm stroke, 75 mm adjustment, PT tapered port, SUS304 rod, and the -S magnet.
Because the 160 mm stroke is under the 300 mm threshold, side-load risks are moderate, but the robust 25 mm rod and M20x1.5 thread handle higher eccentric loads well. For applications that must hold a position without continuous air pressure, this cylinder is not a lock; you should pivot to the SAIL air-released lock or BSAI clamp-lock series instead.
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 SAIJ100BX160-75S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 7068 N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the 160 mm nominal stroke by up to 75 mm, providing a usable travel window of 85 to 160 mm. It decelerates the travel end but does not lock the load without live air pressure.
