About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75S
The AirTAC SAIJ32X750-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 675 to 750 mm, letting you trim the effective stroke by up to 75 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This variant is equipped with a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and ships with a magnet (-S) for use with CMSE reed and DMSE electronic sensors. It uses a PT G1/8 tapered port and relies on variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 675-750mm window during machine setup to accommodate varying product lengths without swapping hardware.
Product Changeover
Quickly adjust the stroke by up to 75mm on packaging lines when switching between different package sizes, minimizing downtime between production runs.
Long-Travel Assembly
Utilize the 750mm stroke for extended linear movements while relying on the rear screw to precisely set the final resting position for component placement.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75S the Right Cylinder?
Choose this 32mm bore when you need 402N push force at 0.5 MPa with the flexibility to fine-tune the retract end position without adding external stops. If your application requires less force, step down to a 25mm bore; if you need more thrust, stepping up to a 40mm bore yields 628N. The rear adjuster acts purely as a travel stop and does not hold the load without live air—use a SAIL or BSAI cylinder if you need true load-holding capability.
Because this model features a 750mm stroke, the 12mm rod requires external guiding to prevent excessive side-loading and binding over long unsupported travels. For a direct ISO 15552 dimensional replacement, match the 32mm bore, 750mm stroke, 75mm adjustment, PT G1/8 port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32AX750-75S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 750mm nominal length down to 675mm. It only sets the travel end and decelerates the load via air cushions; it does not lock the position without continuous air pressure.
