About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30S
The AirTAC SAIJ32X75-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end-point. Outfitted with a SUS420J2 stainless steel rod and PT tapered ports, it delivers 402N of push force at 0.5 MPa. The integrated magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This adjustable model provides a usable travel window of 45 to 75 mm, enabling rapid end-position tuning during commissioning or product changeovers without swapping the hardware. It shares the exact ISO 15552 mounting interface and extruded aluminum barrel of the fixed-stroke SAI series, but utilizes a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) to accommodate the rear stopper mechanism.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30S Is Used
Product Changeovers
Dial in the exact 45 to 75 mm travel distance when switching between slightly different package sizes on a packaging line.
Machine Commissioning
Fine-tune the retract end-position during setup without machining external stop blocks or changing the cylinder.
Variable End Stops
Provides a flexible stroke window for assembly stations that need to adjust the pressing depth based on the component being loaded.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-30S the Right Cylinder?
Choose this 32mm bore when your application requires 402N of thrust at 0.5 MPa with on-the-fly stroke adjustments. If you need higher force, stepping up to the 40mm bore yields 628N of push force. The 30mm adjustment range is perfect for variable end-stops, whereas a fixed SAI cylinder is better for static, unchanging travel limits.
For drop-in ISO 15552 replacement, match the 32mm bore, 75mm nominal stroke, 30mm adjuster, PT port thread, and -S magnet requirement. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. For dead-fall protection, consider the SAIL or BSAI series.
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 SAIJ32AX75-30S FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 75mm nominal stroke by up to 30mm. This creates a usable travel window of 45 to 75mm for precise end-position tuning without replacing the cylinder.
