Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 210mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40
The AirTAC SAIJ32X210-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 40 mm. This creates a usable window of 170 to 210 mm, enabling fine end-position tuning at commissioning without swapping the unit. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, operating at speeds of 30-800 mm/s.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a mechanical travel stop and does not hold the load without live air pressure; for position holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40 Is Used
Machine Changeover
Dial in the 170-210 mm travel window during product size changes on a packaging line without replacing the cylinder or adding external stops.
End-Position Tuning
Fine-tune the retract end-position during commissioning to ensure precise alignment of a 32 mm bore actuator pushing a 402 N load.
Adjustable Stop Setup
Use the rear mechanical stopper to set variable travel limits for testing different clamping distances on a light assembly fixture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-40 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires variable end-stops or frequent product changeovers, rather than a fixed-stroke SAI model. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. At a 210 mm stroke, the 12 mm rod and M10x1.25 thread handle moderate side loads, but an external guide is recommended for heavy lateral forces.
For a true ISO 15552 dimensional replacement, match the 32 mm bore, 210 mm stroke, 40 mm adjustment, PT port threads, and the SUS304 rod material. Note that SAIJ supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on some other series.
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 SAIJ32BX210-40 FAQ
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 80 kgf.
The rear adjuster screw lets you shorten the 210 mm nominal stroke by up to 40 mm, creating a usable travel window of 170 to 210 mm. The adjuster is a travel stop, not a lock, and requires live air to hold the load.
