About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-50
The AirTAC SAIJ32X105-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 55 to 105 mm window. Delivering 563 N of push force at 0.7 MPa, it provides precise end-position control during commissioning without requiring external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This specific configuration utilizes a SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically exposed environments. The PT tapered port threads (G1/8) ensure a tight, reliable pneumatic connection. Remember that the rear adjuster functions purely as a travel stop to set deceleration, not as a load-holding lock; for dead-end load security without live air pressure, an external pilot-operated check valve or a SAIL locking cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-50 Is Used
Product Size Changeovers
Dial in the exact end-stop for different package lengths on a single conveyor line without physically swapping out the cylinder or adding shims.
Machine Setup Calibration
Fine-tune the retract position during initial commissioning to perfectly align a 32 mm bore pushing motion with a delicate tooling head.
Washdown Testing Fixtures
Leverage the SUS304 stainless steel rod to safely cycle test samples through variable travel distances in environments prone to moisture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-50 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 724 N of push force at 0.9 MPa but demands variable end-stops for product size changeovers. If your setup needs less force, stepping down is not an option within the standard profile range, but if you require significantly higher thrust, consider the 40 mm bore which provides 879 N at 0.7 MPa. The massive 50 mm adjustment range on this 105 mm stroke allows you to cut the effective travel in half, making it ideal for testing multiple product lengths on a single fixture. When matching ISO 15552 replacement dimensions, ensure you specify the PT port thread, SUS304 (B) rod material, and the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ32BX105-50 FAQ
The rear adjuster screw allows you to shorten the nominal 105 mm stroke by up to 50 mm, giving you a usable travel window of 55 to 105 mm. It acts as a mechanical stop to set the retract end-position, but it does not lock the load without continuous air pressure.
At a standard operating pressure of 0.7 MPa, the SAIJ32X105-50 provides 563 N of push force and 483 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
