About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-75S
The AirTAC SAIJ32X325-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a 402N push force at 0.5 MPa and provides a usable travel window of 250-325 mm, letting you dial back the nominal 325 mm stroke by up to 75 mm during commissioning.
Built with an SUS420J2 stainless steel rod and a -S magnet for CMSE reed and DMSE electronic sensors, it integrates seamlessly into existing setups. The extruded aluminum barrel includes sensor grooves on both sides, and the rear screw acts purely as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 250 and 325 mm on packaging flaps or guides without machining new hard stops.
Machine Changeover
Quickly adapt the cylinder's effective travel window when switching a production line to a different product size.
Commissioning Calibration
Fine-tune the final end position during initial setup to perfect timing and avoid mechanical crashes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-75S the Right Cylinder?
Select this 32 mm bore when you need precise retract-end positioning without adding external stops, stepping down from a 40 mm bore that yields 528N pull force. Because the 325 mm stroke is relatively long for a 12 mm rod, an external guide is recommended to prevent excessive side-loading and rod deflection.
For load-holding without live air pressure, skip the standard SAIJ and choose a SAIL or BSAI variant. To match this ISO 15552 interchangeable cylinder, specify the 32 mm bore, 325 mm stroke, 75 mm adjustment, PT tapered G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet option.
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 SAIJ32AX325-75S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 325 mm down to a minimum of 250 mm. It only sets the travel end and does not lock the load without live air.
