This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X100-10S, 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 SIJ125X100-10S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X100-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X100-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X100-10S
The AirTAC SIJ125X100-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 125 mm bore and 100 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 90-100 mm window. The stop sets the end position and is not a load lock; use an external rod lock or SAIL variant for held loads.
The direct replacement is the SAIJ125X100-10S, matching the ISO 15552 interface, bore, stroke, force, and mounting. The SAIJ family uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X100-10S Is Used
Press Fit Tuning
Allows precise 90-100 mm extend adjustment for pressing bearings, ensuring exact insertion depth without re-engineering the fixture.
Carton Flap Folding
Accommodates varying package heights by trimming the extend stroke up to 10 mm on-site, preventing over-travel damage to carton flaps.
Pallet Positioning Stops
Provides adjustable end-stop positioning for pallets of slightly different dimensions, allowing 10 mm of field stroke tuning.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X100-10S with the SAIJ125X100-10S
To replace the discontinued SIJ125X100-10S, order the direct replacement SAIJ125X100-10S, which preserves the 125 mm bore, 100 mm stroke, 10 mm adjust window, G1/2 port, and ISO 15552 mounting interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2). Choose the 10 mm adjust window if you need 90-100 mm of extend travel. Retain your FA, LB, or TC mounting hardware. The -S suffix confirms the magnet is present for legacy CS1-B/DS1-B switches. For stroke lengths of 300 mm or greater, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X100-10S
- ✓ 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 SIJ125X100-10S FAQ
