About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-100
The AirTAC SAIJ32X350-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 350 mm stroke that can be dialed back by up to 100 mm, yielding a precise 250-350 mm usable travel window for exact end-position tuning during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop for deceleration, not as a load-holding lock; position holding without live air requires a SAIL or BSAI variant.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-100 Is Used
Product Changeover
Dial in the 250-350 mm travel window rapidly on packaging lines when switching between different carton sizes, eliminating the need for mechanical spacers.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to perfectly align a 402 N pushing action without adding external hard stops.
Variable Diverter
Adjust the stroke length on the fly for a conveyor sorting arm to accommodate different product widths while maintaining a 30-800 mm/s operating speed.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-100 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa but demands a highly variable end-stop. The 100 mm adjustment range allows significant flexibility for product changeovers without swapping cylinders. If your setup requires less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore provides 628 N push force. Conversely, if you need higher clamping forces, consider the 50 mm bore offering 982 N.
Because this model features a 350 mm stroke, the 12 mm rod requires external guidance to prevent excessive side-loading and premature seal wear. When replacing an ISO 15552 cylinder, match the 32 mm bore, 350 mm stroke, 100 mm adjustment, PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). No magnet is specified, so CMSE or DMSE sensors cannot be used without adding the -S option.
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 SAIJ32BX350-100 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 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster acts as a mechanical stop that shortens the effective travel. For the SAIJ32X350-100, you can trim the 350 mm nominal stroke back by up to 100 mm, creating a usable 250-350 mm travel window. It only sets the end position and does not lock the load without live air.
