About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-20
The AirTAC SAIJ32X230-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 210 to 230 mm, allowing you to dial back the nominal 230 mm stroke by up to 20 mm during machine commissioning. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force, making it suitable for light-duty actuation.
This model features a SUS304 stainless steel rod (code B) for enhanced corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjustment screw acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-20 Is Used
End-Position Tuning
Dial in the exact retract distance within the 210-230 mm window during machine commissioning to perfect a pressing or clamping motion.
Product Changeover
Quickly adjust the stroke stop on a packaging line when switching to a different product size, avoiding the need to physically swap cylinders.
Light-Duty Assembly
Leverage the 402 N push force and SUS304 rod for precise, repeatable positioning of small components in a clean or mildly corrosive environment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-20 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your setup requires precise end-position tuning without swapping components or adding external stops. If your application demands higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if you need a fixed travel and want to simplify the bill of materials, the standard AirTAC SAI cylinder is a direct alternative. Because this is a 230 mm stroke, the 12 mm rod and M10x1.25 thread carry moderate side loads; for long unsupported travel, always use an external guide to prevent binding.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 32 mm bore, 230 mm stroke, up to 20 mm adjustment, PT G1/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Note that the SAIJ series omits FB, CA, CB, and CR mounts. If your process requires true load holding without live air, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead, as the adjuster here is only a stop.

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 SAIJ32BX230-20 FAQ
At a standard operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it reaches 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 230 mm down to as little as 210 mm. This provides a 210-230 mm usable window for fine-tuning at commissioning, though it does not lock the load without live air.
