About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-75S
The AirTAC SAIJ32X115-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 40-115 mm usable travel window by allowing you to dial back the 115 mm nominal stroke by up to 75 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during commissioning fine-tuning. It includes a magnet for CMSE and DMSE sensors, with sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster functions strictly as a travel stop to set end positions, not as a lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-75S Is Used
Variable End-Stop Tuning
Dial in the exact 40-115 mm travel distance during machine commissioning to accommodate new product dimensions without changing the cylinder.
Rapid Product Changeover
Quickly adjust the retract stop on a packaging line when switching between different package sizes, saving retooling time.
Stroke Limiting Setup
Prevent over-travel in delicate assembly operations by using the rear screw to mechanically limit the forward motion to a precise window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-75S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, or step up to the 40 mm bore if you need 628 N. The 75 mm adjustment range is ideal for machines processing variable product sizes, allowing rapid end-stop changes without hardware swaps. For strokes of 115 mm, the 12 mm rod and M10x1.25 thread handle moderate side loads, but longer unsupported travel still requires an external guide.
This SAIJ uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552. Remember that the adjuster and air cushions do not hold the load without live air; for position holding, use an external rod lock or pilot-operated check valve.
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 SAIJ32BX115-75S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 80 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 115 mm nominal stroke by up to 75 mm, creating a usable travel window of 40-115 mm. It sets the end position but does not lock the load without live air pressure.
