About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-50S
The AirTAC SAIJ32X800-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 750-800mm usable travel window. Delivering 402N of push force at 0.5MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE or DMSE solid-state sensors. The PT tapered ports ensure tight pneumatic sealing.
By turning the external rear stopper, you can fine-tune the end position at commissioning without adding external stops. Remember the adjuster acts only as a travel stop and does not hold the load without live air; for dead-end holding, consider a SAIL or BSAI cylinder. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-50S Is Used
Variable End-Position Tuning
Dial in the exact 750-800mm retract position during machine commissioning without physically swapping out the entire cylinder or adding bulky external stopper blocks.
Product Changeover Adjustments
Quickly adapt the travel end-stop on packaging lines when handling different product sizes, using the 50mm adjustment range to accommodate new dimensions.
Sensor-Ready Actuation
Leverage the built-in magnet and dual-side sensor grooves to mount CMSE reed or DMSE electronic switches exactly where needed along the 800mm travel path.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-50S the Right Cylinder?
Select this 32mm bore cylinder when you need precise variable end-stops over a long 800mm travel. If your application requires greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. Because the 800mm stroke is substantial for a 12mm rod, an external guide is strongly recommended to prevent excessive side-loading and premature seal wear.
Choose the adjustable SAIJ format over a fixed SAI when machine setups require frequent product changeovers. To match this ISO 15552 replacement exactly, specify: 32mm bore, 800mm stroke, 50mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet option.

- ✓ 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 SAIJ32BX800-50S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 50mm, providing a usable travel window of 750-800mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
At 0.5MPa operating pressure, it provides 402N of push force and 345N of pull force. If you increase the pressure to 0.7MPa, the push force rises to 563N.
