This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-75S, 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.
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X700-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75S
The AirTAC SIJ100X700-75S 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 75 mm on-site, yielding a usable 625-700 mm window from the 700 mm nominal maximum. The direct replacement is the SAIJ100X700-75S, matching the G1/2 port, M20x1.5 rod thread, and 36 mm adjustable cushions.
The SAIJ successor retains the upgraded SAI piston seal (two Y-shaped one-way elements for low start-up pressure and long life) and enables ISO 15552 mounting reuse without frame changes. The stop screw sets the end position but is not a lock; loads drift on air loss, so use an external rod lock or SAIL/BSAI variant for holding. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75S Is Used
Variable Press Stroke
Allows operators to fine-tune the extend position on-site for material pressing tasks where workpiece thicknesses vary.
Adjustable Diverter Arm
Sets precise sorting positions along a conveyor line, enabling quick reconfiguration when product sizes change.
Dynamic End-Stop Positioning
Provides a tunable mechanical end-stop for pallet handling, letting users trim the extend stroke to match pallet dimensions.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-75S with the SAIJ100X700-75S
To replace the discontinued SIJ100X700-75S, order the exact direct replacement SAIJ100X700-75S to preserve the ISO 15552 interface, G1/2 port, and 625-700 mm adjust window. Choose the 75 mm adjust window when you need precise on-site extend tuning without machining. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches. Because the 700 mm stroke is long, account for rod-bending and side-load risks by incorporating external guides to support the rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-75S
- ✓ 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 SIJ100X700-75S FAQ
