The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 80mm 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 SAIJ32X80-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 80 mm stroke that can be fine-tuned down by up to 40 mm, giving you a precise 40-80 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups perfectly.
This variant includes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and ships with a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 fitting size for this bore.

Dial in the 40-80 mm travel window on packaging lines to accommodate varying carton sizes without changing the cylinder.
Fine-tune the retract position during machine commissioning to align tooling precisely without adding external stops.
Leverage the built-in magnet and dual sensor grooves to mount CMSE or DMSE switches for exact position feedback.
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa, stepping down from a 40 mm bore (628 N) for lighter duty, or up from smaller micro-cylinders. The adjustable 40-80 mm window is perfect for machines requiring frequent product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, this cylinder cannot hold a load without live air pressure. For positive load-holding, consider an external pilot-operated check valve or explore the SAIL lock variant. To achieve exact ISO 15552 replacement compatibility, match the 32 mm bore, 80 mm stroke, 40 mm adjustment, PT port, and -S magnet.
Quick checklist
At 0.5 MPa operating pressure, 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 achieves 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 80 mm nominal stroke by up to 40 mm. This creates a 40-80 mm usable travel window for fine-tuning end positions without swapping the cylinder.
