Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-10 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 SAIJ32AX75-10
The AirTAC SAIJ32X75-10 is a double-acting, single-rod profile cylinder dimensionally interchangeable per ISO 15552. It features an extruded aluminum barrel with sensor grooves on both sides and a rear adjusting screw that allows you to trim the effective stroke. With a 75 mm nominal stroke and a 10 mm adjustment range, it provides a usable travel window of 65 to 75 mm for fine-tuning the retract end position at commissioning.
Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, this 32 mm bore unit uses a PT G1/8 port and an M10x1.25 rod thread. The rod is constructed from SUS420J2 stainless steel for improved corrosion resistance, and it lacks a magnet, meaning it will not trigger CMSE or DMSE sensors. The rear adjuster acts strictly as a travel stop to decelerate the stroke, not as a lock, so it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-10 Is Used
Machine Setup Tuning
Dial in the exact 65 to 75 mm retract position during initial commissioning to align tooling without machining external stopper blocks.
Product Changeover
Quickly adjust the stroke end-stop by up to 10 mm when switching between slightly different product sizes on a packaging line.
Variable End Stops
Fine-tune the clamping or pressing position on small assemblies where a fixed 75 mm stroke would bottom out too hard against the workpiece.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-10 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa and precise end-position tuning without swapping components. If you need higher thrust, stepping up to the 40 mm bore yields 628 N of push force, while dropping to a smaller bore would sacrifice too much power. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, operating at speeds between 30 and 800 mm/s.
To match this ISO 15552 replacement, verify the 32 mm bore, 75 mm nominal stroke, 10 mm adjustment range, PT G1/8 port, and SUS420J2 stainless steel rod. The available mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because the stroke is under 300 mm, side-load stress on the M10x1.25 rod is minimal, though external guides are still recommended for heavy lateral loads. For applications requiring true load-holding without live air pressure, consider the SAIL or BSAI series instead.

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 SAIJ32AX75-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds ranging from 30 to 800 mm/s.
The rear adjusting screw acts as a stopper that lets you shorten the 75 mm nominal stroke by up to 10 mm, creating a 65 to 75 mm usable travel window. It decelerates the stroke but does not lock the load without live air pressure.
