About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-75S
The AirTAC SAIJ100X190-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 115 to 190 mm, allowing you to dial back the nominal 190 mm stroke by up to 75 mm during commissioning. Delivering 5497 N of push force at 0.7 MPa, it handles heavy-duty positioning tasks.
This SKU is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It uses a G1/2 port and relies on the standard SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-75S Is Used
Product Changeover Adjustment
Dial in the exact retract distance from 115 to 190 mm when switching product sizes on a packaging line, eliminating the need for physical spacer changes.
Heavy-Duty End Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy actuators, using the rear screw to fine-tune the final resting position during machine setup.
Corrosive Environment Automation
Utilize the SUS304 stainless steel rod and standard sensor grooves for precise, magnetically confirmed positioning in washdown or corrosive manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-75S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires high thrust (5497 N at 0.7 MPa) alongside variable end-stop tuning. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa. The 75 mm adjustment range is ideal for product changeovers on a line, letting you fine-tune the retract position without swapping hardware or adding external stops.
Remember that the rear adjuster functions as a mechanical stop, not a lock; it cannot hold the load without live air. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. Because the usable travel reaches up to 190 mm, ensure adequate external guiding to prevent side-load damage to the M20x1.5 rod thread.
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 SAIJ100BX190-75S FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder generates a push force of 5497 N and a pull force of 3681 N. It can deliver a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke from its 190 mm nominal length, providing a usable travel window between 115 and 190 mm. It decelerates the travel end but does not lock the load without live air pressure.
