Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30
The AirTAC SAIJ32X75-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 45-75 mm usable travel window from its 75 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for corrosion resistance and uses a PT tapered G1/8 port. Sensor grooves on both sides of the extruded aluminum barrel allow direct mounting of switches.
The external adjustment screw lets you fine-tune the retract end position at commissioning without swapping cylinders or adding external stops. The adjuster functions strictly as a travel stop, not a lock, meaning it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 45 and 75 mm during commissioning to perfectly match varying product sizes without external stopper hardware.
Machine Changeover
Rapidly adjust the end position on automated lines when switching between product runs, minimizing downtime and avoiding cylinder replacement.
Compact Force Positioning
Utilize the 402 N push force in a space-constrained ISO 15552 footprint where exact end-of-stroke positioning is more critical than maximum thrust.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30 the Right Cylinder?
Choose this 32 mm bore when you need precise variable end-stops in a compact footprint; step up to the 40 mm bore if your application requires 628 N of push force at 0.5 MPa. The rear screw is ideal for machine setup and product changeovers, providing a distinct advantage over a fixed-stroke SAI cylinder. This configuration includes a SUS420J2 stainless steel rod, PT port threads, and no magnet. It supports the SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX75-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 30 mm, creating a usable travel window of 45 to 75 mm. It acts as a mechanical stop to set the end position and does not lock the load without air pressure.
