About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-100S
The AirTAC SAIJ32X350-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 250-350 mm usable travel window by allowing you to trim the 350 mm nominal stroke back by up to 100 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread.
This unit includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel offers sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to fine-tune end positions at commissioning; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-100S Is Used
Machine Changeover
Dial in the 250-350 mm travel window during product size changes without physically replacing the cylinder or adding external stops.
Sensor Integration
The integrated magnet works directly with DMSE solid-state and CMSE reed switches mounted in the dual sensor grooves for precise positioning.
Corrosive Environments
The SUS304 stainless steel rod provides reliable actuation in packaging or food processing lines where moisture is present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-100S the Right Cylinder?
Choose this 32 mm bore when 402 N push force at 0.5 MPa is sufficient, stepping up to a 40 mm bore (628 N) if your payload increases. An adjustable stroke is ideal for machine setups requiring variable end-stops without swapping cylinders. Because the 350 mm stroke is significant, the 12 mm rod needs external guiding to prevent side-load damage.
For ISO 15552 interchangeability, match the 32 mm bore, 350 mm stroke, 100 mm adjustment, PT port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. If you need true load-holding without air pressure, use a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ32BX350-100S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull force. At 0.7 MPa it provides 563 N push force.
The rear adjuster lets you shorten the 350 mm nominal stroke by up to 100 mm, creating a 250-350 mm travel window. It acts as a mechanical stop, not a lock.
