Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 220mm 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 SAIJ32BX220-75
The AirTAC SAIJ32X220-75 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 75 mm. This creates a highly flexible 145-220 mm usable stroke window, letting you dial in the exact retract end-position during commissioning without swapping out the entire actuator or bolting on external stops. Delivering 402 N of push force at 0.5 MPa, it fits light-duty handling tasks perfectly.
This specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance and features tapered PT ports. The extruded aluminum barrel includes sensor grooves on both sides, and while this base model lacks a magnet, the grooves are ready to accept electronic DMSE or reed CMSE switches if you add a magnet later. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75 Is Used
Machine Changeovers
Rapidly reconfigure the 145-220 mm travel window during product size changeovers without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the exact retract position at commissioning to perfect alignment and avoid mechanical crashes, using the rear screw rather than shims.
Variable Stop Arms
Actuate diverter arms or pushers on a conveyor line where the required retract distance varies based on the package size being handled.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75 the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of push force at 0.5 MPa; if you need more power, stepping up to the 40 mm bore yields 628 N. The 75 mm adjustment range is exceptionally wide, making this cylinder ideal for machines that process multiple product sizes and need vastly different retract end-stops on the same line. Unlike a fixed-stroke SAI cylinder, this SAIJ model lets you fine-tune the travel window mechanically during changeovers.
Because the 220 mm stroke exceeds 300 mm? No, but even at 220 mm, the 12 mm rod and M10x1.25 thread provide a robust interface, though long unsupported strokes still require an external guide to prevent side-loading damage. This actuator uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552. If your process requires true load-holding without continuous air pressure, you must look to the SAIL or BSAI series, as the adjuster here is not a lock.

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 SAIJ32BX220-75 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the nominal 220 mm stroke by up to 75 mm. This provides a usable travel window of 145 to 220 mm, which can be fine-tuned during setup without changing the cylinder.
At a standard 0.5 MPa operating pressure, the SAIJ32X220-75 provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
