About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-50
The AirTAC SAIJ32X700-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 650-700mm usable travel window, allowing you to dial back the nominal 700mm stroke by up to 50mm during commissioning. Delivering 402N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses an SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning external physical stops are required if position detection is not added. The PT tapered port threads match the G1/8 standard for this 32mm bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-50 Is Used
Product Changeovers
Quickly adjust the 650-700mm retract distance to accommodate different package lengths on a packaging line without changing hardware.
Commissioning Fine-Tuning
Dial in the exact end-of-stroke position during machine setup to prevent mechanical interference, using the rear screw rather than external stops.
Light-Duty Positioning
Move lighter payloads with 402N of push force, relying on the SUS420J2 stainless rod for environments where minor corrosion resistance is beneficial.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-50 the Right Cylinder?
Choose this 32mm bore when your application requires roughly 402N push force at 0.5 MPa; step up to a 40mm bore if you need 628N. The adjustable 650-700mm window is ideal for product changeovers on a line, letting you fine-tune the retract end position without swapping cylinders or adding external stopper blocks. For a fixed end position, a standard SAI cylinder would suffice.
Because the 700mm stroke is long relative to the 32mm bore, an external guide is strongly recommended to prevent excessive rod side-loading. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider a SAIL or BSAI cylinder. ISO 15552 replacement match: 32mm bore, 700mm stroke, 50mm adjust, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounts, no magnet.
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 SAIJ32AX700-50 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50mm, providing a usable travel window of 650-700mm. It acts as a physical stop to set the retract end position precisely during setup.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
