This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-50, 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 SIJ100X700-50
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-50 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 SAIJ100X700-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-50
The AirTAC SIJ100X700-50 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. The G1/2 port and 36 mm cushions match the standard profile. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 650-700 mm range from the 700 mm nominal maximum.
As this SIJ is discontinued, the direct replacement is the SAIJ100X700-50, retaining the interface, force, and port. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-50 Is Used
Press Fit Tuning
Field-trim the 650-700 mm extend stroke by up to 50 mm to set precise press depth for bearings without changing the cylinder body.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-50 with the SAIJ100X700-50
To replace the discontinued SIJ100X700-50, order the direct replacement SAIJ100X700-50, reusing your existing FA, LB, or TC ISO 15552 mounts. The 50 mm adjust window is ideal for field-tuning the 650-700 mm extend stroke without machining. Because this SKU lacks the -S suffix, it has no magnet and cannot take a magnetic switch. For the 700 mm stroke, support the rod against bending and use external guides to manage side loads. The stop screw sets end position but provides no load holding on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-50
- ✓ 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 SIJ100X700-50 FAQ
Yes, the SIJ100X700-50 is discontinued. The direct replacement is the SAIJ100X700-50, which shares the ISO 15552 interface, 700 mm stroke, 50 mm adjust window, and G1/2 port. The SAIJ family also upgrades the piston seal to two Y-shaped one-way elements for longer life.
The external stop screw trims the extend stroke by up to 50 mm on-site, giving a usable 650-700 mm range. The stop sets end position only and is not a load lock.
