About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-100
The AirTAC SAIJ32X210-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous 110-210 mm usable travel window, allowing you to dial back the 210 mm nominal stroke by up to 100 mm during machine setup or product changeover. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and PT tapered ports for demanding environments.
This adjustable model uses an external stopper screw to set the retract end-position precisely without adding external stops or swapping the cylinder. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-100 Is Used
Product Changeover
Quickly adapt the 110-210 mm travel window on packaging lines when handling slightly different carton sizes without replacing the actuator.
Machine Setup
Fine-tune the retract end-position during initial commissioning to perfect the alignment of tooling and prevent mechanical crashes.
Variable End Stops
Dial in the exact stroke needed for delicate assembly tasks, using the rear screw to set the precise 100 mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-100 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires variable end-stops and fine end-position tuning at commissioning, rather than a fixed-stroke SAI cylinder. If you need greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 210 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to prevent excessive side-load on the 12 mm rod.
To match this ISO 15552 interchangeable cylinder, verify the 32 mm bore, 210 mm nominal stroke, 100 mm adjustment range, PT port threads, and the SUS304 (code B) rod material. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since no magnet is specified, position sensing via CMSE or DMSE sensors is not supported without modification.
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 SAIJ32BX210-100 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 210 mm nominal stroke down to as little as 110 mm. This creates a 110-210 mm usable window for precise end-position tuning without swapping cylinders.
