About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-30S
The AirTAC SAIJ32X210-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 180-210 mm usable travel window by allowing you to dial back the 210 mm nominal stroke by up to 30 mm. In the 32 mm bore class, it generates 402 N of pull force at 0.5 MPa and 563 N of push force at 0.7 MPa, making it suitable for light-duty precision tasks.
This variant is configured with an SUS420J2 stainless steel rod for improved corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this model includes a magnet (-S), it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors for position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-30S Is Used
Machine Changeover
Quickly adjust the end-stop by up to 30 mm during product size changes on a packaging line without disassembling the cylinder mount.
End-Position Tuning
Fine-tune the retract position during commissioning to dial in the exact 180-210 mm travel distance required for delicate picking operations.
Variable End Stops
Set precise mechanical limits for testing fixtures where the effective stroke needs to be adjusted on the fly without adding external stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-30S the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires fine end-position tuning at commissioning or during product changeover without swapping the cylinder or bolting on external stops. If your setup needs greater thrust, stepping up to the 40 mm bore yields 528 N of pull force at 0.5 MPa. For load-holding requirements without live air pressure, note that the SAIJ rear adjuster acts only as a travel stop and does not function as a lock; consider the SAIL or BSAI series instead.
This model is dimensionally interchangeable per ISO 15552 mounting interface standards. It features a PT port thread, an SUS420J2 stainless steel rod, and a magnet for CMSE/DMSE sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. Because the 210 mm stroke is relatively short, side-load concerns are minimal, but long unsupported strokes still require an external guide.
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 SAIJ32AX210-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of pull force and 345 N of push force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back from the 210 mm nominal stroke by up to 30 mm, providing a usable 180-210 mm window. It only sets the travel end and does not hold the load without live air pressure.
