About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-75S
The AirTAC SAIJ32X105-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 30 to 105 mm. Delivering 402 N of push force at 0.5 MPa, it is designed for applications requiring precise end-position tuning without external stops. The PT tapered port threads and SUS304 stainless steel rod (option B) ensure robust corrosion resistance.
This model includes a magnet for electronic DMSE or reed CMSE sensors and features air cushions at both ends to decelerate the load. The rear adjuster acts strictly as a travel stop for commissioning flexibility, not a load-holding lock; for fail-safe position holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-75S Is Used
Variable End-Stop Tuning
Dial in the exact 30 to 105 mm travel window during machine commissioning to perfect positioning without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper on automated lines to accommodate different product sizes without adding external mechanical stops.
Sensor-Ready Positioning
Utilize the integrated magnet with DMSE electronic or CMSE reed switches to confirm end-of-stroke travel across the adjusted range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-75S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa, but select a 40 mm bore (628 N push) if your load demands higher thrust. An adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, whereas a fixed SAI cylinder lacks this commissioning flexibility.
Because this is a 105 mm stroke, side-load is minimal, but long unsupported strokes always require an external guide. To match this ISO 15552 replacement exactly, verify the 32 mm bore, 105 mm stroke, 75 mm adjustment, PT G1/8 port, Basic/LB/TC mounting, and the -S magnet option.
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 SAIJ32BX105-75S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum push force is 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 105 mm stroke by up to 75 mm, creating a usable travel window of 30 to 105 mm. This stopper only sets the end position and does not lock the load without live air.
