The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 115mm 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.
The AirTAC SAIJ32X115-75-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, equipped with a magnet for position sensing. It provides 402N of push force and 345N of pull force at 0.5 MPa. By turning the external rear stopper screw, you can trim the effective travel back by up to 75 mm, creating a precise 40-115 mm usable stroke window for exact end-position tuning at commissioning.
This 32 mm bore version features a 12 mm carbon steel rod, an M10x1.25 rod thread, and PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, seamlessly accepting AirTAC CMSE reed and DMSE solid-state electronic switches. The rear adjuster acts purely as a travel stop to set deceleration and end limits; it does not lock or hold the load without live air pressure.

Dial the stroke back from 115 mm to 40 mm instantly on the production line to accommodate varying package lengths without changing cylinders.
Fine-tune the final retract position during machine commissioning using the rear screw, ensuring precise alignment without adding external mechanical stops.
Utilize the dual sensor grooves with CMSE reed or DMSE electronic switches to confirm the adjusted end position in your control system.
Choose this adjustable-stroke cylinder when your machine setup requires variable end stops or frequent product-size changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. If you need slightly higher force, stepping up to a 40 mm bore yields 628N of push force at 0.5 MPa, while dropping down is not an option in this ISO 15552 range.
For load-holding without continuous air pressure, note that this standard SAIJ adjuster is not a lock; you would need an external rod lock, a pilot-operated check valve, or an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder. To replace an ISO 15552 cylinder, match the 32 mm bore, 115 mm stroke, 75 mm adjustment range, PT port thread, and the -S magnet requirement. Because the nominal stroke is 115 mm, side loads are minimal, but long unsupported strokes still require an external guide.
Quick checklist
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear stopper screw allows you to shorten the 115 mm nominal stroke by up to 75 mm, giving an adjustable travel window of 40 to 115 mm. The adjuster sets the end position and deceleration, but it does not lock or hold the load without live air pressure.
