About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-75S
The AirTAC SAIJ100X175-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 100 to 175 mm, allowing you to dial back the nominal 175 mm stroke by up to 75 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads while maintaining dimensionally interchangeable ISO 15552 mounting dimensions.
This SKU includes a SUS304 stainless steel rod for superior corrosion resistance and is equipped with a magnet for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered ports ensure a reliable, leak-free pneumatic connection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-75S Is Used
Machine Changeovers
Dial in the 100-175 mm travel window during product size changes to set new end positions without replacing the cylinder or adding external stops.
End-Position Tuning
Fine-tune the exact retract distance at commissioning using the rear screw, ensuring precise alignment before finalizing the machine setup.
Variable End Stops
Adapt automated lines to different part lengths by adjusting the stroke back up to 75 mm, providing flexible manufacturing without mechanical rework.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-75S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (providing 1559 N push at 0.5 MPa) is insufficient for your process. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end stops for machine changeovers without physically swapping components. To match this ISO 15552 replacement exactly, verify the 100 mm bore, 175 mm stroke, 75 mm adjustment, PT port thread, and the -S magnet.
Remember that the rear adjuster acts as a travel stop to decelerate the load, not a lock; it will not hold the load without live air. For position holding without pressure, consider an external rod lock or the SAIL/BSAI series. The 25 mm rod and M20x1.5 thread offer high rigidity, but long unsupported strokes still require external guide rails.
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 SAIJ100BX175-75S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm. This creates a usable travel window between 100 and 175 mm, allowing you to set the exact end position without swapping the cylinder.
