About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-30S
The AirTAC SAIJ32X280-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 250-280 mm usable travel window by allowing you to trim up to 30 mm from the 280 mm nominal stroke. In the 32 mm bore class, it delivers a 563 N push force at 0.7 MPa and features a SUS304 stainless steel rod for superior corrosion resistance.
This unit includes a magnet for position sensing via AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. It uses a G1/8 port and omits the FB, CA, CB, and CR mounting options, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-30S Is Used
Machine Changeover
Dial in the exact retract position within the 250-280 mm window when switching product sizes on a packaging line.
End-Position Tuning
Fine-tune the stroke during commissioning without swapping the cylinder or bolting on external mechanical stops.
Variable End Stops
Adjust the stopping point precisely for different pallet lengths on a conveyor handling system.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-30S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when you need to fine-tune the retract end-position during commissioning or product changeover without adding external stops. If your application requires higher force, stepping up to the 40 mm bore yields a 879 N push force at 0.5 MPa.
Because the 280 mm stroke is relatively long for a 32 mm bore, ensure you use an external guide to prevent excessive side-loading on the 12 mm rod. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. This SKU is dimensionally interchangeable per ISO 15552 and uses PT tapered ports.
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 SAIJ32BX280-30S FAQ
At the standard 0.5 MPa operating pressure, this 32 mm bore cylinder provides a 402 N push force and a 345 N pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel by up to 30 mm. This creates a 250-280 mm usable stroke window for fine-tuning the end position at commissioning.
