About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-20S
The AirTAC SAIJ32X350-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. This model provides a usable travel window of 330-350 mm, allowing you to dial back the 350 mm nominal stroke by up to 20 mm without adding external stops. It delivers 402 N of push force at 0.5 MPa and includes a SUS304 stainless steel rod for superior corrosion resistance.
Equipped with a magnet for position sensing, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The extruded aluminum barrel uses PT tapered ports (G1/8), and the rear adjuster functions strictly as a travel stop to set deceleration endpoints, not as a lock to hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-20S Is Used
Machine Changeover
Quickly fine-tune the 330-350 mm travel window during product size transitions without physically swapping out the entire cylinder.
End-Stop Calibration
Dial in the exact retract position during commissioning using the rear adjuster, ensuring precise placement without external mechanical stops.
Variable Position Routing
Accommodate slight variations in package sizes on a conveyor line by adjusting the effective stroke by up to 20 mm on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-20S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your setup requires fine-tuning of the retract end during commissioning or product changeover. If your application demands greater thrust, stepping up to the 50 mm bore yields 982 N of push force at 0.5 MPa. Because the 350 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to prevent excessive side-loading on the M10x1.25 rod.
This SAIJ variant supports the reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For exact ISO 15552 replacement matching, verify the 32 mm bore, 350 mm stroke, 20 mm adjustment, PT G1/8 port, and the -S magnet requirement. If true load-holding without live air is needed, consider the SAIL or BSAI series instead of relying on the rear stopper.

- ✓ 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 SAIJ32BX350-20S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 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 acts as a mechanical stop that allows you to shorten the effective travel from the nominal 350 mm down to 330 mm. It sets the deceleration endpoint but does not lock or hold the load without continuous air pressure.
