About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-100
The AirTAC SAIJ32X550-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 550 mm nominal stroke that can be fine-tuned backward by up to 100 mm, creating a precise 450-550 mm usable travel window. Operating at 0.15-1.0 MPa, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance and features PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the 550 mm stroke is relatively long for a 32 mm bore, external guidance is recommended to prevent excessive side-loading on the 12 mm rod.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-100 Is Used
Product Changeovers
Dial in the 450-550 mm travel window on the fly to accommodate different package sizes on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve precise alignment without adding external stopper blocks.
Variable End Stops
Provide adjustable actuation endpoints for diverter gates on conveyors where the exact stopping distance requires field calibration.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-100 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires exact end-position tuning during commissioning or frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your setup requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if lower friction or smaller footprint is needed, dropping to a smaller bore would be necessary.
When ordering a direct ISO 15552 replacement, confirm the following: 32 mm bore, 550 mm stroke, 100 mm adjustment range, PT port threads, and no magnet (standard). Note that the rear adjuster functions strictly as a mechanical stop to set the travel end and does not lock the load; for dead-air position holding, consider an AirTAC SAIL or BSAI cylinder. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ32AX550-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum rated pressure of 0.9 MPa, the push force increases to 724 N.
The SAIJ32X550-100 features a rear adjusting screw that allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 450-550 mm, enabling you to set the exact retract position without replacing the cylinder.
