This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X700-10S, 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 SIJ125 Double Rod Adjustable Cylinder SIJ125X700-10S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X700-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X700-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X700-10S
The AirTAC SIJ125X700-10S 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 10 mm on-site, yielding a usable 690-700 mm stroke (700 mm nominal maximum).
The direct replacement is the SAIJ125X700-10S, retaining the same interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X700-10S Is Used
Press Fit Tuning
Allows precise 0-10 mm on-site extend stroke adjustment for pressing assemblies, ensuring exact insertion depth without machining spacers.
Pallet Stop Positioning
Provides a field-tunable end-stop for varying pallet lengths on a 125 mm bore actuator, offering 6136 N of stopping force at 0.5 MPa.
Heavy Load Diverter
Delivers robust push force for diverting heavy goods, with the 10 mm adjust window allowing fine-tuning of the diverter arm endpoint.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X700-10S with the SAIJ125X700-10S
To replace the discontinued SIJ125X700-10S, specify the SAIJ125X700-10S direct, keeping the 700 mm stroke, 10 mm adjust window, and G1/2 port. Reuse existing ISO 15552 FA, LB, or TC mounts. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (SAIJ uses current AirTAC switches). Because the 700 mm stroke is long, use external guides to prevent rod bending and side-load damage. The stop screw trims extend position but does not hold loads; for air-loss holding, use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X700-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X700-10S FAQ
Yes, the SIJ125X700-10S is discontinued. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw allows trimming the extend stroke by up to 10 mm on-site (usable stroke 690-700 mm). The stop sets end position only and is not a load lock; for load holding, use SAIL, BSAI, or an external rod lock.
