About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-10S
The AirTAC SAIJ32X270-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a SUS304 stainless steel rod. The built-in adjuster provides a usable travel window of 260-270mm, allowing you to fine-tune the retract end-position by up to 10mm without adding external stops.
This unit includes a magnet for position sensing, supporting AirTAC CMSE reed and DMSE electronic switches. It uses a G1/8 PT port and relies on variable air cushions at both ends to decelerate the load. The rear adjuster acts strictly as a travel stop, so it will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-10S Is Used
End-Position Tuning
Dial in the exact 260-270mm retract distance during machine commissioning without swapping out the entire cylinder.
Product Changeovers
Quickly adapt end-stops on a production line when handling slightly different package sizes or component heights.
Light Assembly Actuation
Provides reliable 402N push force for precise, light-duty pressing and indexing tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-10S the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa and on-the-fly end-position tuning during commissioning. If your setup demands greater thrust, stepping up to the 40mm bore yields 628N. The SAIJ32X270-10-S is ideal for product changeovers where a fixed-stroke SAI cylinder would require manual shimming. To replace an ISO 15552 cylinder, match the 32mm bore, 270mm stroke, 10mm adjustment, G1/8 PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
Because the 270mm stroke is 300mm or less, side-load risks are moderate, but you should still ensure proper guidance for the 12mm rod. For applications needing position holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ32BX270-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder generates 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 270mm stroke by up to 10mm, creating a usable travel window of 260-270mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
