About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-40
The AirTAC SAIJ32X105-40 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and uses a 12mm SUS304 stainless steel rod with an M10x1.25 thread. The rear adjustment screw allows you to trim the nominal 105mm stroke back by up to 40mm, creating a precise 65-105mm usable travel window for exact end-position tuning.
This adjustable design eliminates the need to swap cylinders or add external stops during machine setup or product changeover. The rear adjuster functions purely as a travel stop to set the retract end position and relies on the variable air cushion for deceleration; it does not hold the load without live air pressure. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-40 Is Used
End-Position Calibration
Dial in the exact retract distance within the 65-105mm window during machine commissioning to perfect pick-and-place trajectories without changing hardware.
Product Size Changeover
Quickly adapt the cylinder's stroke on packaging lines when handling varying carton lengths, using the rear screw to set new travel limits.
Adjustable Clamping
Provide precise clamping force and position by fine-tuning the travel end, ensuring delicate components are not crushed during assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-40 the Right Cylinder?
Choose this 32mm bore cylinder when an application requires 402N of push force at 0.5 MPa (or 563N at 0.7 MPa) alongside variable end-stop positioning. If your process requires less force, stepping down to a 40mm bore yields 628N of push force at 0.5 MPa, while needing more force would mean stepping up. The adjustable stroke is ideal for commissioning fine-tunes or accommodating slight product size variations on a line without mechanical rebuilds.
Because this model features a PT tapered port thread and no magnet, it is configured for basic pneumatic control without position sensing. To replace an ISO 15552 cylinder, match the 32mm bore, 105mm stroke, 40mm adjustment, PT G1/8 port, and appropriate mounting. Remember that the rear adjuster is a stop, not a lock; for load-holding without live pressure, consider the SAIL or BSAI series.
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 SAIJ32BX105-40 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 105mm stroke by up to 40mm. This creates a usable travel window of 65-105mm, allowing you to fine-tune the end position at commissioning without swapping the cylinder.
