About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-40S
The AirTAC SAIJ32X700-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 660 to 700 mm. It delivers 402 N of push force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet supports AirTAC CMSE reed and DMSE solid-state sensors for precise position feedback.
This model utilizes a PT tapered port thread and includes variable air cushions at both ends to protect the mechanics during high-speed operations. The external rear stopper allows you to fine-tune the retract position at commissioning without adding external stops or swapping the cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-40S Is Used
Variable End-Stop Configuration
Dial in the exact retract distance between 660 and 700 mm during machine commissioning to accommodate different product sizes without changing hardware.
Product Changeover Systems
Quickly adjust the stroke window on packaging lines when switching between different package lengths, saving setup time and reducing downtime.
Sorting and Diverting
Use the precise end-position tuning to accurately position diverters on conveyor belts, ensuring products are pushed cleanly into the correct lanes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-40S the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and require a 660-700 mm travel window for product size changeovers. If your application requires significantly more force, stepping up to the 40 mm bore yields 628 N of push force. Conversely, if you need less force in a smaller footprint, the 25 mm bore provides 247 N.
Selecting the SAIJ adjustable-stroke design over a fixed SAI cylinder is ideal when you need variable end-stops for machine setup or product-size changes. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without continuous pressure, use a SAIL lock or BSAI clamp-lock cylinder. Because the 700 mm stroke is long, an external guide is recommended to manage side-load stress on the 12 mm rod.

- ✓ 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 SAIJ32BX700-40S 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 pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the nominal 700 mm stroke by up to 40 mm, giving an effective travel window of 660 to 700 mm. The adjuster acts as a mechanical stop and does not function as a lock to hold the load without live air pressure.
