About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-50S
The AirTAC SAIJ100X190-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 140 to 190 mm, allowing you to dial back the nominal 190 mm stroke by up to 50 mm during commissioning without adding external stops. It delivers a robust 5497 N push force at 0.7 MPa, making it ideal for heavy-duty positioning tasks.
This SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet for position sensing. The dual sensor grooves on the extruded aluminum barrel support AirTAC CMSE reed and DMSE electronic switches. It uses a G1/2 port and offers a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-50S Is Used
Machine Changeover
Fine-tune the 140-190 mm travel window during product size changeovers to set precise end positions without swapping the actuator.
Variable End Stops
Use the rear adjuster to set custom retraction limits on the fly for multi-format assembly lines, avoiding hard mechanical stops.
Heavy Duty Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or fixtures while benefiting from the corrosion-resistant SUS304 rod.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-50S the Right Cylinder?
Select this 100 mm bore actuator when a 63 mm bore (2182 N push at 0.5 MPa) is insufficient for your load, but an 80 mm bore (3518 N push at 0.5 MPa) leaves too little margin. The 50 mm adjustment range is perfect for product changeovers on a packaging line, letting you fine-tune the end position rapidly. Choose this adjustable-stroke SAIJ over a fixed SAI when your machine setup requires variable end stops.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous pneumatic pressure, consider the SAIL or BSAI series. Because the 190 mm stroke is under the 300 mm threshold, side-load risks are moderate, but the 25 mm rod and M20x1.5 thread still provide excellent resistance to deflection. This unit is dimensionally interchangeable per ISO 15552.

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 SAIJ100BX190-50S FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 190 mm down to 140 mm. This creates a 50 mm adjustable window for fine-tuning the end position at commissioning without changing the cylinder.
At an operating pressure of 0.7 MPa, the SAIJ100X190-50-S provides a push force of 5497 N and a pull force of 5497 N. It can deliver up to 7068 N push force at 0.9 MPa.
