Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-100
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 270mm 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 SAIJ32BX270-100
The AirTAC SAIJ32X270-100 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 100 mm. This creates a highly flexible 170-270 mm usable stroke window, letting you dial in exact end positions during commissioning or product changeovers without swapping out the barrel or adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a piston magnet, meaning it is not set up for AirTAC CMSE or DMSE position sensing. The extruded aluminum barrel includes sensor grooves on both sides for standard ISO 15552 mounting, and the rear adjuster functions strictly as a travel stop—it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-100 Is Used
Machine Changeovers
Quickly adjust the retract end-position by up to 100 mm when switching product sizes on a packaging line, eliminating the need to physically swap cylinders for different format parts.
Commissioning Calibration
Fine-tune the 170-270 mm stroke window during initial machine setup to perfect timing and avoid mechanical crashes, dialing in the exact stop point without external shims.
Corrosive Environments
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in humid or mildly corrosive settings where a standard carbon steel rod would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-100 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning across a 170-270 mm travel window, rather than relying on a fixed-stroke SAI cylinder. If your process demands higher clamping or lifting force, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. Conversely, if you need to hold a load mechanically without continuous air pressure, this standard SAIJ is not the right choice—you should look at the SAIL air-released lock or BSAI clamp-lock series instead, as the rear adjuster here is only a stop.
Because this cylinder has a 270 mm stroke, the unsupported rod length extends significantly during operation; even with a 12 mm rod and M10x1.25 thread, you should incorporate an external guide to prevent excessive side-loading and premature seal wear. This model is dimensionally interchangeable with ISO 15552 cylinders and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It operates at speeds of 30-800 mm/s and uses G1/8 ports.

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 SAIJ32BX270-100 FAQ
The rear adjuster acts as an external stopper that lets you shorten the nominal 270 mm stroke by up to 100 mm, providing a usable travel window of 170-270 mm. It allows fine-tuning of the retract end-position at commissioning without swapping the cylinder, but it is a stop, not a lock, and cannot hold the load without live air pressure.
At a 0.5 MPa operating pressure, the SAIJ32X270-100 provides 402 N of push force and 345 N of pull force. If your application requires more thrust, stepping up to the 40 mm bore increases the push force to 628 N at the same pressure.
