About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-40
The AirTAC SAIJ32X230-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 190 to 230 mm. Delivering 402 Newtons of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance. The barrel uses an extruded aluminum profile with sensor grooves on both sides, ensuring it is dimensionally interchangeable with ISO 15552 cylinders.
This model features a PT tapered port thread (G1/8) and omits heavy mounting options like FB, CA, CB, and CR, focusing instead on a streamlined set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The rear stopper acts solely as a travel deceleration point and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-40 Is Used
Machine Changeover
Dial in the exact 190 to 230 mm end-stop during product size transitions without adding external mechanical stops.
Commissioning Fine-Tune
Trim the travel window by up to 40 mm on-site to perfect the seating force against a workpiece.
Variable End-Stop Assembly
Use the rear adjuster to accommodate slight variations in incoming part lengths on an automated line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-40 the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning during machine commissioning or product changeover without swapping out the entire cylinder. It provides 402N of push force at 0.5 MPa; if your application requires less force, stepping down is not an option in this series, but stepping up to a 40mm bore yields 628N. The rear adjuster is a stop, not a lock, so maintaining position requires continuous air pressure. For load-holding without live pressure, an external pilot-operated check valve or the SAIL lock series is required.
When replacing an ISO 15552 cylinder, match the 32mm bore, 230mm nominal stroke, 40mm adjustment range, PT port thread, and the required mounting bracket. Because the 230mm stroke is relatively long for a 32mm rod, an external guide is recommended to prevent excessive side-load wear on the rod seals.
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 SAIJ32BX230-40 FAQ
At a 0.5 MPa operating pressure, this 32mm bore cylinder generates 402 Newtons of push force and 345 Newtons of pull force. It can reach up to 724 Newtons of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 230mm nominal stroke by up to 40mm, creating a usable travel window of 190 to 230mm. This stopper only sets the end position and decelerates the piston; it does not lock or hold the load without continuous air pressure.
