This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X75-75TC, 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.
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X75-75TC
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X75-75TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X75-75TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X75-75TC
The AirTAC SIJ100X75-75TC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 75mm on-site, setting the exact end position without needing a custom-length barrel. As a direct replacement, the SAIJ100X75-75TC matches the original interface, force, and TC mounting.
The SAIJ upgrade features an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note that the stop screw sets end position but is not a load lock; for held loads use an external rod lock or the SAIL/BSAI variants. This SKU lacks a -S magnet and cannot take a magnetic switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X75-75TC Is Used
Press Fit Tuning
Allows operators to fine-tune the extend stroke on-site by up to 75mm to dial in the exact pressing depth for bearings without swapping cylinders.
Variable Length Diverter
Provides adjustable reach for a diverting arm on a conveyor, letting maintenance shorten the extend end position to accommodate different package sizes.
Adjustable End Stop
Sets a precise mechanical end position for a pallet locating mechanism, permitting 0-75mm of on-site stroke adjustment to handle varied pallet dimensions.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X75-75TC with the SAIJ100X75-75TC
To replace the discontinued SIJ100X75-75TC, order the exact direct replacement SAIJ100X75-75TC to retain the same ISO 15552 interface, 75mm nominal stroke, 75mm adjust window, and TC mounting. Choose the 75mm adjust window when you need to trim the extend stroke on-site by up to 75mm. The TC mount provides a center trunnion interface for pivoting. Because this SKU lacks the -S magnet, it cannot support a magnetic switch. For stroke lengths of 300mm or more, verify your side-load limits to prevent excessive rod wear.
Replacement checklist
