The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 60mm stroke, G3/8 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 SAIJ80X60-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 60 mm travel by up to 40 mm. This yields a usable stroke window of 20 to 60 mm, giving you exact end-position control at commissioning without adding external stops or swapping the unit. The 80 mm bore delivers 2513 N of push force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa for demanding press operations.
This variant features an SUS420J2 stainless steel rod for enhanced corrosion resistance, PT tapered port threads, and a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets found on some standard cylinders.

Quickly fine-tune the travel end-position from 20 to 60 mm during product size transitions on a packaging line without replacing the cylinder.
Dial in the exact clamping depth for assembly operations, using the 4523 N of available force at 0.9 MPa to seat components accurately.
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches for precise end-of-stroke detection in automated stations.
Choose this 80 mm bore when your application requires significantly more force than the 50 mm class (982 N at 0.5 MPa) but does not need the full 3927 N push of a 100 mm cylinder. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, replacing the need to stock multiple fixed-stroke SAI cylinders. When matching an ISO 15552 replacement, align the 80 mm bore, 60 mm nominal stroke, 40 mm adjustment, G3/8 port, and the -S magnet requirement.
Because the rear adjuster acts purely as a mechanical stop and the air cushions handle deceleration, neither will hold a load without live air pressure. If your fixture requires fail-safe load holding, consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders instead.
Quick checklist
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw mechanically limits the piston's retraction, allowing you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 20 to 60 mm, which can be fine-tuned during commissioning without changing the cylinder.
