About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-40S
The AirTAC SAIJ32X230-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 190 to 230 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, supporting position feedback via CMSE reed or DMSE electronic sensors.
Equipped with a PT tapered G1/8 port, this unit allows precise end-position tuning during commissioning without swapping hardware. The rear adjuster acts purely as a travel stop and relies on live air pressure, meaning it will not hold a load mechanically. For secure load-holding without air, an external rod lock or a SAIL pneumatic lock cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-40S Is Used
Machine Changeover
Dial in the 190-230 mm travel window during product size transitions without physically replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke at commissioning to perfect the timing of a 402 N push assembly, compensating for mechanical tolerance stack-up.
Diversion Timing
Adjust the actuator length on a conveyor diverter to precisely synchronize the stroke endpoint with varying package dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-40S the Right Cylinder?
Choose this 32 mm bore if your application requires less thrust than the 40 mm bore (which provides 628 N at 0.5 MPa) but still needs precise variable end-stops. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed SAI cylinder locks you into one travel distance. When replacing an ISO 15552 unit, match the 230 mm stroke, 40 mm adjustment range, PT G1/8 port, and the -S magnet option. Because the 230 mm stroke is substantial for a 32 mm bore, use an external guide to prevent side-loading damage to the M10x1.25 rod thread. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX230-40S 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 the maximum 1.0 MPa pressure, it provides up to 82 kgf.
The rear adjuster screw lets you shorten the 230 mm nominal stroke by up to 40 mm, creating a usable travel window of 190 to 230 mm. The adjuster is a mechanical stop, not a lock, so it requires live air pressure to maintain the end position.
