About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-75S
The AirTAC SAIJ32X230-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 230 mm stroke that can be fine-tuned down by up to 75 mm, creating a usable travel window between 155 mm and 230 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and includes a magnet for position sensing.
This model features PT tapered port threads and operates at speeds of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop to dial in the retract end position during commissioning; it is not a locking device and will not hold a load without live air pressure. For load-holding requirements, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-75S Is Used
Machine Changeover
Dial in the 155-230 mm travel window during product size changes without physically swapping the cylinder or repositioning hard stops.
Variable End Stops
Use the rear adjuster to set precise retract positions for feeding varying material lengths on an automated line.
Sensor Calibration
Leverage the -S magnet with DMSE electronic sensors to confirm exact positions while trimming the stroke during initial commissioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-75S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning without swapping cylinders or adding external stopper blocks on a machine changeover. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because this unit features a 230 mm stroke, the 12 mm rod should be guided externally if subjected to significant side loads to prevent premature seal wear.
To match this exact configuration for an ISO 15552 replacement, specify a 32 mm bore, 230 mm nominal stroke, 75 mm adjustment range, PT port threads, SUS304 (B) rod material, and the -S magnet option for CMSE reed or DMSE electronic sensors. Mounting is limited to the SAIJ subset: 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 SAIJ32BX230-75S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 75 mm. This gives you a usable travel window of 155 to 230 mm, letting you fine-tune the end position at commissioning without changing the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801 N.
