About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-75
The AirTAC SAIJ32X125-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 50-125 mm usable travel window, allowing you to dial back the effective stroke by up to 75 mm during commissioning without swapping out the unit. Built with a SUS304 stainless steel rod and PT tapered port threads, it delivers 402 N of push force at 0.5 MPa.
This model uses an extruded aluminum barrel with sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure. It supports AirTAC CMSE reed and DMSE electronic sensors, and its mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-75 Is Used
End-Position Tuning
Fine-tune the retract end-position precisely during machine commissioning without adding external stopper blocks.
Product Changeover
Quickly adjust the 50-125 mm travel window to accommodate varying product sizes on the same assembly line.
Fixture Calibration
Dial in the exact clamping distance on test fixtures using the rear adjuster, avoiding cylinder swaps.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-75 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa. If you need less force, dropping to a smaller bore is an option, but stepping up to a 40 mm bore yields 628 N at the same pressure. The 75 mm adjustment range is ideal for machines that undergo frequent product-size changeovers, replacing the need to bolt on external stops or buy a fixed-stroke SAI cylinder.
Because the rear screw is a travel stop and not a lock, this cylinder will not hold a load if air pressure drops. For fail-safe load holding, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 32 mm bore, 125 mm stroke, PT port threads, and the chosen mounting interface.
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 SAIJ32BX125-75 FAQ
The rear adjuster allows you to mechanically shorten the effective stroke by up to 75 mm, creating a 50-125 mm usable travel window. It acts as a stop to fine-tune the end position without changing the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
