About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-30
The AirTAC SAIJ32X55-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 25 to 55 mm, letting you dial in the exact retract end-position during machine setup without swapping hardware. The 32 mm bore delivers 402 N of push force at 0.5 MPa, scaling up to 724 N at 0.9 MPa.
This variant uses a SUS304 stainless steel piston rod for corrosion resistance and features PT tapered port threads. It carries the standard SAI variable air cushions at both ends, but note that the rear adjuster acts purely as a mechanical stop—it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-30 Is Used
Position Calibration
Fine-tune the 25-55 mm retract distance during equipment commissioning to perfectly align picking heads without adding external stopper blocks.
Product Changeover
Quickly adapt the cylinder's effective stroke on the fly when running a new package size through a packaging line, minimizing downtime.
Variable End-Stops
Use the 30 mm adjustment range to dial in the exact end-of-stroke position for delicate pressing or clamping tasks that require precise depth control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-30 the Right Cylinder?
Choose this adjustable-stroke model when your application requires variable end-stops or frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If you need higher thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. To match this SKU as an ISO 15552 replacement, verify the 32 mm bore, 55 mm nominal stroke, 30 mm adjustment range, PT G1/8 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the 55 mm stroke is short, side-loading is minimal, but always ensure the load is guided to prevent rod binding. If your process requires true load-holding without continuous air pressure, this cylinder will not suffice—consider the SAIL or BSAI locking series instead.
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 SAIJ32BX55-30 FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force, reaching 724 N push at 0.9 MPa. It uses a 12 mm SUS304 stainless steel rod, M10x1.25 rod threads, and a PT G1/8 port.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 55 mm nominal stroke by up to 30 mm, creating a 25 to 55 mm usable travel window. It only sets the travel end and does not lock or hold the load without live air pressure.
