Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-20S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 750mm 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 SAIJ32AX750-20S
The AirTAC SAIJ32X750-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the travel window down from a 750 mm nominal stroke to a 730 mm minimum. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a built-in magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, accepting AirTAC CMSE reed switches or DMSE solid-state electronics.
This model utilizes PT tapered port threads (G1/8) and operates at speeds from 30 to 800 mm/s. The rear adjuster acts purely as a mechanical stop to set the exact retract end-position during commissioning; it is not a locking device and cannot hold a load without live air pressure. For position holding without continuous air supply, an external pilot-operated check valve or a related SAIL pneumatic lock cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-20S Is Used
Machine Changeover
Dial in the exact retract distance within the 730-750 mm window during product size transitions without physically replacing the cylinder or adding external stopper blocks.
Variable End Stops
Set precise ejection or positioning endpoints on a moving line, using the rear adjuster to compensate for mechanical wear or varying package dimensions.
Commissioning Fine-Tune
Trim the effective stroke by up to 20 mm during initial machine setup to perfectly time the 402 N push stroke without re-machining mounting plates.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-20S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning during machine setup or product changeover without swapping out physical components. If your process needs less thrust, stepping down is not an option from this bore, but moving up to a 40 mm bore increases the 0.5 MPa push force to 628 N. Conversely, if higher forces are needed, the 50 mm bore provides 982 N. The adjustable rear stopper provides a 20 mm trimming range, offering flexibility that a fixed-stroke SAI cylinder cannot match.
Because this SKU features a 750 mm stroke, the 12 mm diameter rod is highly susceptible to side-loading and deflection over that extended length; an external guide rail must be used to prevent premature seal wear and binding. To replace an existing ISO 15552 cylinder, match the 32 mm bore, 750 mm stroke, 20 mm adjustment range, PT port threads, and the -S magnet. Note that SAIJ mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting the FB, CA, CB, and CR brackets.

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 SAIJ32AX750-20S 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. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear external screw stopper allows you to shorten the effective travel from the 750 mm nominal stroke down to 730 mm. The adjuster functions as a travel stop and does not lock the load; live air pressure is required to maintain position.
