About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-50S
The AirTAC SAIJ32X105-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a 402N push force at 0.5 MPa and provides a usable travel window of 55 to 105 mm, allowing you to dial back the nominal 105 mm stroke by up to 50 mm during machine setup. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE solid-state switches for exact end-position detection.
This configuration uses a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance, paired with a PT tapered port thread. The rear adjuster acts strictly as a mechanical stop to fine-tune the retract end position without adding external stops, while the variable air cushions manage end-of-stroke deceleration. It utilizes a reduced SAIJ mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-50S Is Used
Machine Changeover
Dial in the exact retract position within the 55-105 mm window during product size changes without swapping out the entire cylinder or adding external stop blocks.
End-Stop Tuning
Fine-tune the final end position at machine commissioning using the rear adjuster, compensating for mechanical tolerances in the fixture setup.
Sensor-Ready Positioning
Utilize the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches precisely along the adjusted travel path for automated feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-50S the Right Cylinder?
Select this 32mm bore cylinder when your application requires precise end-position tuning at commissioning or frequent product-size changeovers, benefiting from the 55-105 mm adjustable travel window. If your setup needs higher force, stepping up to the 40mm bore yields a 628N push force at 0.5 MPa, but the 32mm bore keeps the footprint compact while offering an M10x1.25 rod thread suitable for lighter side loads. For applications requiring the cylinder to hold a load without continuous live air pressure, note that this plain SAIJ model cannot lock in place; consider an AirTAC SAIL or BSAI series for positive holding.
When replacing an ISO 15552 cylinder, verify the 32mm bore, 105mm nominal stroke, 50mm adjustment range, PT port thread, and the required mounting interface. Because this is a profile cylinder, it is dimensionally interchangeable with ISO 15552 mounting dimensions rather than relying on tie-rod construction. The -S magnet option ensures compatibility with CMSE and DMSE sensors.

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 Adjustable Cylinder SAIJ32 SAIJ32BX105-50S FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides a push force of 402N and a pull force of 345N. At the maximum pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this 105mm nominal stroke model, the -50 adjustment code allows you to trim the usable stroke back by up to 50mm, creating a 55 to 105mm adjustable travel window without changing the cylinder itself.
