About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-75S
The AirTAC SAIJ32X800-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 725-800 mm window. Delivering 402 N of push force at 0.5 MPa, it uses a 12 mm stainless steel SUS304 rod and a PT G1/8 port. The integrated magnet supports CMSE reed and DMSE electronic sensors for precise position tracking.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during machine changeovers. The rear adjuster acts strictly as a travel stop to set the end position, not a lock. For load-holding without live air pressure, an external rod lock or related SAIL series is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-75S Is Used
Machine Changeover
Quickly dial in the 725-800 mm travel window during product size changes without physically swapping out the entire actuator.
End-Position Trimming
Use the rear stopper to fine-tune the exact retract position during machine commissioning, avoiding the need for external mechanical stops.
Long-Stroke Sorting
Handles long-travel sorting tasks on a line, where the 800 mm stroke and 75 mm adjustment flexibility accommodate varying package sizes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-75S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N push force at 0.5 MPa with a long 800 mm stroke. The 75 mm adjustment range is ideal for dialing in exact end positions during commissioning without replacing the cylinder. If your setup needs less force, stepping down is not an option in this size, but stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
Because the 800 mm stroke creates an unsupported length on a 12 mm rod, an external guide is recommended to prevent excessive side-loading. This SAIJ configuration includes a SUS304 stainless steel rod, PT tapered ports, and a -S magnet. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX800-75S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the nominal 800 mm stroke by up to 75 mm, creating a usable travel window of 725-800 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
