This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X100-75S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.

The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X100-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X100-75S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X100-75S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ32X100-75S. It uses an external stop screw to trim the extend stroke by up to 75mm on-site, yielding a usable 25-100mm extension. The SAIJ direct retains the exact interface, force, and mounting.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. The -S suffix provides a piston magnet for CS1-B/DS1-B switches.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Adjusts the extend stroke on-site to accommodate multiple material thicknesses without swapping cylinders, using the 75mm window to set precise drilling depths.
Tunes the extension endpoint to handle changing package sizes on a packaging line, ensuring accurate diverting without reprogramming the controller.
Provides field stroke tuning for push-off arms that must handle varying product widths, allowing operators to dial in the 25-100mm usable stroke mechanically.
To replace the discontinued SIJ32X100-75S, order the direct replacement SAIJ32X100-75S, which preserves the 32mm bore, 100mm nominal stroke, 75mm adjust window, G1/8 port, and mounting. Choose the 75mm adjust window if your application requires field-tuning the extend stroke down to a 25mm minimum. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches. Because the nominal stroke is 100mm, no side-load note for strokes >=300mm applies.
Replacement checklist
Yes, the SIJ32X100-75S is discontinued. The direct replacement is the SAIJ32X100-75S. It shares the same ISO 15552 interface, 32mm bore, 100mm nominal stroke, 75mm adjust window, G1/8 port, and mounting hardware. The SAIJ upgrade also features an upgraded piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 75mm on-site, giving a usable extension range of 25-100mm. The stop sets end position and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ32X100-75S replacement — usually within 7-8 hours.
