This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X25-30, 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 SIJ100X25-30
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X25-30 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 SAIJ100X25-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-30
The AirTAC SIJ100X25-30 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 30 mm on-site, yielding a usable 0-25 mm stroke window. As a direct replacement, the SAIJ100X25-30 matches the ISO 15552 mounting interface, bore, force, and adjust window exactly.
The SAIJ upgrade introduces an improved two-piece Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet and cannot accept legacy CS1-B/DS1-B sensors. The external stop sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-30 Is Used
Short-Stroke Clamping
Apply up to 7068 N of clamping force at 0.9 MPa on machining fixtures, using the 30 mm stop screw to dial in the exact 0-25 mm grip depth on-site.
Transfer Diverter
Actuate a routing flap on a packaging line where the 25 mm extend stroke must be fine-tuned to match varying product widths without changing the cylinder.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X25-30 with the SAIJ100X25-30
To replace the discontinued SIJ100X25-30, order the direct replacement SAIJ100X25-30, which preserves the G1/2 port, M20x1.5 rod thread, and 36 mm cushion. Choose the 30 mm adjust window when you need precise on-site end-position tuning for a 25 mm nominal stroke. Mounting reuses genuine ISO 15552 interface attachments (Basic, FA, LB, TC). Because this SKU has no -S magnet, magnetic sensing is impossible. For any stroke over 300 mm, carefully manage side-load guides to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X25-30
- ✓ 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 SIJ100X25-30 FAQ
Yes, the SIJ100X25-30 is discontinued. The direct replacement is the SAIJ100X25-30. It shares the identical ISO 15552 interface, 100 mm bore, 25 mm stroke, 30 mm adjust window, G1/2 port, and mounting options, while adding an upgraded piston seal.
The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable 0-25 mm stroke window. The stop sets end position and is not a load lock.
