About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-30S
The AirTAC SAIJ32X30-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. With a nominal 30 mm stroke, this configuration provides a highly flexible 0 to 30 mm usable travel window, making it ideal for applications requiring exact end-position tuning at commissioning without swapping out the cylinder. It delivers a 402 N push force at 0.5 MPa and utilizes a SUS304 stainless steel rod for superior corrosion resistance.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which mount directly into the dual-side sensor grooves on the extruded aluminum barrel. The PT tapered port threads ensure a tight, reliable pneumatic connection. The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without live air pressure, so an external rod lock or SAIL cylinder is required for load-holding.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-30S Is Used
Machine Changeover
Dial in the retract position up to 30 mm during product size changes without physically replacing the cylinder or adding external stopper blocks.
Commissioning Calibration
Fine-tune the end-of-stroke position during initial setup to absorb minor mechanical tolerances and achieve precise sensor triggering.
Compact Positioning
Leverage the 402 N push force and 0-30 mm travel window for exacting, compact positioning tasks in confined assembly machinery.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-30S the Right Cylinder?
Choose this 32 mm bore when your application requires a compact force class, offering 402 N push and 345 N pull at 0.5 MPa. If your machine requires higher clamping power, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. The SAIJ32X30-30-S is specifically selected over a fixed SAI cylinder when you need variable end-stops to accommodate product changeovers or fine-tune the retract position on the fly. It supports a speed range of 30-800 mm/s and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options. For exact ISO 15552 replacement matching, verify the 30 mm stroke, 30 mm adjustment, PT G1/8 port, and the -S magnet requirement.

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 SAIJ32BX30-30S FAQ
At 0.5 MPa operating pressure, the 32 mm bore provides a push force of 402 N and a pull force of 345 N. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the nominal 30 mm stroke by up to 30 mm, providing a usable travel window of 0 to 30 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
