About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-30
The AirTAC SAIJ32X450-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel within a 420 to 450 mm window. Equipped with a SUS304 stainless steel rod, it provides 563 N of push force at 0.7 MPa, making it suitable for lighter-duty positioning tasks.
This model uses a PT tapered G1/8 port and includes adjustable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel integrates sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if position feedback is later required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-30 Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within the 420-450 mm window during machine setup, accommodating minor dimensional variations without changing the cylinder.
Product Size Changeover
Quickly adjust the stroke on packaging or sorting lines to handle different product lengths, reducing downtime between production runs.
Light-Duty Positioning
Leverage the 563 N push force at 0.7 MPa and SUS304 rod for precise movement of smaller components in clean or mildly corrosive environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-30 the Right Cylinder?
Choose this 32 mm bore when an application demands precise end-position tuning during commissioning or product changeover, avoiding the need to swap cylinders or bolt on external stops. If your setup requires greater thrust, stepping up to the 40 mm bore yields 879 N of push force at 0.7 MPa.
Because the nominal stroke is 450 mm, an external guide is recommended to prevent excessive side loading on the piston rod. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. This profile cylinder is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX450-30 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 420 to 450 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At an operating pressure of 0.7 MPa, the SAIJ32X450-30 provides a push force of 563 N and a pull force of 483 N. It can deliver a maximum push force of 724 N at 0.9 MPa.
