This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X175-75, 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 SIJ100X175-75
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X175-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X175-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-75
The AirTAC SIJ100X175-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. It uses an external stop screw to trim the extend stroke by up to 75mm on-site, giving a usable range of 100-175mm from the 175mm nominal maximum. The direct replacement is the SAIJ100X175-75, matching the interface, force, and porting.
The SAIJ upgrade incorporates an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. This SKU lacks a magnet (-S) and cannot take a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-75 Is Used
Variable Depth Forming
Adjusts the extend stroke on-site to accommodate different material thicknesses in a single press station without changing the entire cylinder.
Adjustable Transfer Stops
Tunes the stop position for varying package sizes on a conveyor line, allowing rapid changeovers by trimming the extend stroke by up to 75mm.
Tiered Pallet Positioning
Provides field stroke tuning to engage different pallet heights, ensuring precise alignment without requiring multiple dedicated actuators.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-75 with the SAIJ100X175-75
To replace the discontinued SIJ100X175-75, order the exact direct replacement SAIJ100X175-75 to reuse your existing ISO 15552 mounting interface and G1/2 porting. Choose the 75mm adjust window if you need to trim the extend stroke on-site between 100mm and 175mm. Mounting options include FA, LB, and TC brackets. Because this specific SKU has no -S magnet, it cannot support magnetic sensing; add -S if you need legacy CS1-B/DS1-B switch accuracy. For stroke lengths of 300mm or more, verify side-load limits to prevent excessive rod wear. Note that the stop screw only sets end position and does not hold the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X175-75
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-75 FAQ
Yes, the SIJ100X175-75 is discontinued. The direct replacement is the SAIJ100X175-75, which matches the ISO 15552 mounting interface, 100mm bore, 175mm stroke, 75mm adjust window, and G1/2 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 75mm on-site, yielding a usable range of 100-175mm. The stop sets end position only; it is not a load lock.
