About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-30S
The AirTAC SAIJ32X300-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 270 to 300 mm, allowing you to dial back the nominal 300 mm stroke by up to 30 mm during commissioning without adding external stops. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it fits lighter-duty tasks perfectly.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance, PT tapered ports, and an integrated magnet for position sensing. You can pair the -S magnet with AirTAC CMSE reed switches or DMSE solid-state electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to manage end-of-travel deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-30S Is Used
Product Changeover Dials
Quickly fine-tune the 270-300 mm travel window during machine setup to accommodate slightly different package lengths without swapping the cylinder.
Variable End-Stop Positioning
Use the rear adjuster to set precise retract end-positions for light-duty machining or gauging tasks requiring 402 N of push force.
Light Transfer Diverter
Employ the 32 mm bore and SUS304 rod on a packaging line to divert lightweight goods, adjusting the stroke as product dimensions vary.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-30S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, stepping down from a 40 mm bore that yields 628 N if you need to conserve space and air volume. An adjustable stroke is selected over a fixed SAI model when you need fine end-position tuning for product changeovers on a shared line. Because this cylinder features a 300 mm stroke, long unsupported travel can induce side loads; ensure you use an external guide to prevent rod binding.
For a drop-in ISO 15552 replacement, match the 32 mm bore, 300 mm stroke, 30 mm adjustment range, PT port thread, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI series.

- ✓ 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 SAIJ32BX300-30S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 300 mm nominal stroke down to 270 mm, creating a 30 mm adjustable window. It sets the end position but does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ32X300-30-S provides 402 N of push force and 345 N of pull force. It can reach 724 N of push force at 0.9 MPa.
