About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-20S
The AirTAC SAIJ32X145-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 125 to 145 mm, allowing you to dial back the nominal stroke by up to 20 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant integrates a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It uses a G1/8 port and omits the FB, CA, CB, and CR mounting interfaces, supporting only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-20S Is Used
Machine Changeover
Fine-tune the retract distance by up to 20 mm during product size transitions without swapping out the cylinder or reengineering the fixture.
End-Stop Calibration
Dial in the exact 125 to 145 mm travel window at commissioning to perfect positioning cues for delicate assembly tasks.
Variable Product Diverter
Adjust the stroke on the fly to accommodate different package widths on a packaging line while maintaining reliable 402 N push force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-20S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires precise end-position tuning on the fly, such as adapting to slightly varying product sizes on a conveyor. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, you would step down to a 25 mm bore for lighter loads. Because the stroke is 145 mm, external side-load guides are recommended to prevent rod binding.
The rear adjuster screw acts strictly as a travel stop to fine-tune the retract end position; it does not hold the load without live air pressure. For true fail-safe load holding, select an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder. To match this ISO 15552 interchangeable replacement, specify: 32x145 stroke, 20 mm adjustment, PT tapered port thread, SUS304 rod, and the -S magnet.
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 SAIJ32BX145-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 145 mm nominal stroke down to as little as 125 mm. It only sets the end position and does not lock the load without continuous air pressure.
