About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-75
The AirTAC SAIJ32X180-75 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 75 mm. This creates a highly flexible 105-180 mm usable travel window, making it ideal for machine setups that require variable end-stops without swapping hardware. It delivers 402N of push force at 0.5 MPa and operates at speeds of 30-800 mm/s.
This model uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threading (G1/8). The extruded aluminum barrel includes sensor grooves on both sides, although this specific SKU is configured without a magnet. The rear adjuster functions strictly as a travel stop to fine-tune deceleration, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-75 Is Used
Machine Setup Tuning
Dial in the exact 105-180mm travel window during commissioning to perfect end-position timing without adding external stopper blocks.
Product Changeover
Quickly adjust the stroke for different product sizes on the same line, leveraging the 75mm trim range to handle multiple part formats.
Deceleration Control
Use the rear stop combined with the 27mm cushion to precisely set the retract end-point and manage kinetic energy on tooling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-75 the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your application requires frequent product changeovers or fine end-position tuning at commissioning. It provides 402N of thrust at 0.5 MPa; if your fixture needs less force, stepping down is difficult as 32mm is the smallest ISO 15552 size, but if you need more power, a 40mm bore offers 628N at 0.5 MPa. Because the 180mm stroke is under the 300mm threshold, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads.
The rear adjuster screw sets the travel end and manages deceleration alongside the variable air cushions, but it will not hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series, or use an external pilot-operated check valve. To match this ISO 15552 replacement: bore 32mm, stroke 180mm, adjustment 75mm, port PT G1/8, mounting options limited to Basic, FA, LB, TC, FTC, TCM1, TCM2, and no magnet (-S omitted).

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 SAIJ32AX180-75 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster acts as an external stopper that lets you shorten the nominal 180mm stroke by up to 75mm, creating a usable travel window of 105-180mm. It sets the end-position and deceleration point but does not lock the load without live air.
