About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-10S
The AirTAC SAIJ32X55-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 45 to 55 mm without adding external stops. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
This adjustable-stroke model includes a magnet for CMSE and DMSE sensors, utilizing the extruded aluminum barrel with sensor grooves on both sides. It supports a speed range of 30-800 mm/s and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-10S Is Used
Machine Setup Changeover
Dial in the exact 45-55 mm end position during machine format changes without swapping the cylinder or adding external stopper blocks.
Variable End Stops
Fine-tune the retract stroke on the fly for delicate pressing or positioning tasks that require sub-millimeter adjustments at commissioning.
Corrosive Environment Handling
Leverage the SUS304 stainless steel rod and 402 N push force for light-duty actuation in washdown or chemical-prone laboratory settings.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-10S the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-position tuning at commissioning or during product changeovers, stepping down from a 40 mm bore (528 N pull at 0.5 MPa) to save space. The rear adjuster acts as a travel stop to decelerate the piston, but it does not hold the load without live air; for true load-holding, consider an external rod lock or the BSAI clamp-lock series.
To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 55 mm stroke, 10 mm adjustment range, PT tapered ports, and the -S magnet for solid-state DMSE or reed CMSE sensor integration. Since the stroke is under 300 mm, side-load stress is minimal, though the M10x1.25 rod thread handles standard loads well.
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 SAIJ32BX55-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 55 mm nominal stroke by up to 10 mm, creating a usable travel window of 45 to 55 mm. The adjuster acts as a stop to set the end position, but it is not a lock and requires live air to hold the load.
