About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-50S
The AirTAC SAIJ32X80-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the travel window from 30 to 80 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features a magnet for CMSE or DMSE sensor integration.
This adjustable-stroke model uses a PT tapered port thread and includes a 50 mm rear stopper mechanism to set precise end positions without adding external stops. The rear adjuster acts strictly as a travel stop to dial in the exact end-of-stroke, while the integrated air cushions manage deceleration; neither component will hold a load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-50S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 30 and 80 mm during machine commissioning to accommodate varying material thicknesses without external stopper blocks.
Product-Size Changeovers
Rapidly adjust the effective stroke on packaging lines when switching between different product sizes, using the integrated 50 mm rear screw to set new endpoints.
Corrosive Environment Testing
Leverage the SUS304 stainless steel rod and standard aluminum barrel in light chemical washdown areas while tracking piston position via DMSE solid-state sensors.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-50S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of thrust at 0.5 MPa and demands exact end-position tuning on the fly. If your setup needs significantly more force, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. The 50 mm adjustment range is ideal for product-size changeovers on a line, letting you shift the end-stop natively rather than swapping out a fixed-stroke SAI cylinder. For load-holding without live air pressure, consider a SAIL or BSAI cylinder instead. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ32BX80-50S FAQ
The SAIJ32X80-50-S has a nominal 80 mm stroke that can be adjusted back by up to 50 mm, providing a usable travel window of 30 to 80 mm. It generates 402 N of push force and 345 N of pull force at 0.5 MPa.
The rear adjuster acts as a mechanical stop that physically limits the piston's travel to fine-tune the end position. It is not a locking device and cannot hold a load without continuous air pressure; for true load-holding, a SAIL or BSAI cylinder is required.
