About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75S
The AirTAC SAIJ32X100-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a broad usable travel window of 25 to 100 mm, allowing you to dial back the nominal 100 mm stroke by up to 75 mm during machine commissioning. This bore delivers 402 N of push force at 0.5 MPa, scaling to 724 N at 0.9 MPa.
Built with a SUS304 stainless steel rod and a PT tapered port, this unit includes a magnet for position sensing. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops, while the extruded aluminum barrel retains standard ISO 15552 mounting dimensions.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 25 to 100 mm during machine setup to accommodate different material lengths without swapping cylinders.
Product Size Changeover
Quickly adjust the stroke window on packaging lines when switching between product formats, minimizing downtime and avoiding external stop hardware.
Commissioning Calibration
Fine-tune the final end-of-stroke position during initial machine build to compensate for mechanical tolerances using the rear adjustment screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75S the Right Cylinder?
Choose this 32 mm bore when you need precise variable end-stops for product changeovers. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The SAIJ32X100-75-S is selected over a fixed SAI cylinder when a machine handles varying part sizes and needs on-the-fly travel tuning.
This cylinder uses a PT port and offers the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not hold a load without live air pressure, as the adjuster is a stop rather than a lock; for true load-holding, consider the SAIL or BSAI series. The integrated magnet works with AirTAC CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ32BX100-75S FAQ
At a 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw lets you mechanically shorten the 100 mm nominal stroke by up to 75 mm, providing a usable travel window of 25 to 100 mm. It functions as a travel stop and does not lock the load without live air pressure.
