About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-30S
The AirTAC SAIJ32X550-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 520 to 550 mm, allowing you to dial back the end position by up to 30 mm during commissioning. With a 32 mm bore, it generates 563 N of push force at 0.7 MPa.
This unit includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered ports. Equipped with a magnet, it supports AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side barrel grooves. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-30S Is Used
Machine Changeovers
Dial in the exact end-stop from 520 to 550 mm during product size transitions without swapping the cylinder or adding external shims.
Variable End Stops
Fine-tune the retract position on packaging lines to accommodate varying package lengths quickly and accurately.
Commissioning Calibration
Trim the stroke by up to 30 mm during initial machine setup to perfectly sync the cylinder's travel with adjacent tooling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX550-30S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires 563 N of push force at 0.7 MPa, but demands exact end-position tuning without adding external stops. If your process requires less force, stepping down is not an option for heavier loads; conversely, if you need 879 N, step up to the 40 mm bore. The adjustable 520-550 mm window is ideal for product changeovers on a line.
Because the 550 mm stroke is relatively long for a 32 mm rod, external guidance is recommended to prevent excessive side-load wear. This SAIJ model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. For applications requiring true load-holding without live air, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ 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 SAIJ32AX550-30S FAQ
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder generates 563 N of push force and 506 N of pull force. The maximum force at 1.0 MPa is 82 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 550 mm down to 520 mm, giving a 30 mm tuning window. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
