About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-10S
The AirTAC SAIJ32X250-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 250 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 240-250 mm usable travel window for product changeovers. Delivering 402 N of push force at 0.5 MPa, it handles light-duty positioning with high repeatability.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for position sensing. The extruded aluminum barrel houses sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches without extra brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-10S Is Used
Machine Changeover
Dial in the 240-250 mm travel window during product size changes without swapping the cylinder or adding external mechanical stops.
Light Diverting
Provides 402 N of push force at 0.5 MPa to actuate lightweight routing gates and diverter arms on packaging lines.
Sensor-Ready Positioning
The integrated magnet works seamlessly with DMSE electronic sensors to confirm end-of-stroke positions in automated assemblies.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N to overcome higher friction. The 10 mm rear adjuster allows you to dial in the exact end-of-stroke position during commissioning without adding external stops. If you need to hold a load vertically without continuous air pressure, do not rely on this cylinder's adjuster or air cushions, as they act only as travel stops; instead, specify an AirTAC SAIL or BSAI locking cylinder.
To match this ISO 15552 interchangeable cylinder exactly, specify: 32 mm bore, 250 mm stroke, 10 mm adjustment, PT tapered port threads, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet option. Because the stroke is 250 mm, ensure external guiding is used to prevent excessive side-loading on the rod.
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 SAIJ32BX250-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 250 mm nominal stroke by up to 10 mm, providing a usable travel window of 240-250 mm for fine-tuning end positions at commissioning.
