This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X25-10, 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 SIJ100X25-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 25mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X25-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10
The AirTAC SIJ100X25-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 25 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 15-25 mm window. This stop sets the end position; it is not a load lock, so use an external rod lock or pilot-operated check valve for held loads.
The direct replacement is the SAIJ100X25-10, matching the ISO 15552 interface, bore, force, and mounting. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. This non-magnetic SKU lacks a -S sensor groove and cannot accept a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10 Is Used
Transfer Diverters
Actuate routing gates where field stroke tuning is needed to accommodate varying package sizes without swapping the entire cylinder body.
Press Insertion
Press bearings or pins with a precise end position, using the external stop to set the final 15-25 mm insertion depth accurately.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-10 with the SAIJ100X25-10
To replace the discontinued SIJ100X25-10, order the direct replacement SAIJ100X25-10, keeping the 10 mm adjust window and 25 mm nominal stroke. Choose your adjust window based on the exact on-site extend trim needed (here, shortening by up to 10 mm). Mounting interchange is strictly via ISO 15552 interface dimensions (Basic, FA, LB, TC). Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. Since the stroke is under 300 mm, standard side-load limits apply without special derating.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X25-10
- ✓ 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 SIJ100X25-10 FAQ
Yes, the SIJ100X25-10 is discontinued. The direct replacement is the SAIJ100X25-10, which shares the same ISO 15552 interface, 100 mm bore, 25 mm stroke, 10 mm adjust window, G1/2 port, and mounting options. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for longer life.
It is double-acting double-rod with a 10 mm external stop screw window, allowing a usable extend stroke of 15-25 mm (nominal 25 mm is max). The stop sets end position and is not a load lock.
