This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X100-40S, 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 SIJ100X100-40S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X100-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40S
The AirTAC SIJ100X100-40S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder featuring a built-in piston magnet. Its external stop screw allows you to trim the extend stroke by up to 40 mm on-site, providing a usable extend range of 60-100 mm from the 100 mm nominal maximum. As a direct, the SAIJ100X100-40S shares the exact interface, force, and mounting.
The SAIJ replacement retains the ISO 15552 mounting dimensions for seamless reuse of FA, LB, and TC brackets, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Choosing this adjustable stop often beats welding an external stop to a fixed SAI cylinder because it allows precise field tuning. Note the stop sets end position only; it is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40S Is Used
Variable Press Stroke
Allows on-site extend stroke tuning up to 40 mm to accommodate material thickness variations without re-engineering the press fixture.
Adjustable Diverter Arm
Fine-tunes the extend reach of a sorting diverter on a conveyor line to handle varying package widths dynamically.
Calibrated Sealing Head
Provides precise end-position control for a packaging sealing head, allowing 60-100 mm stroke adjustments for different carton depths.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40S with the SAIJ100X100-40S
To replace the discontinued SIJ100X100-40S, order the SAIJ100X100-40S, ensuring you keep the -S suffix for the piston magnet required by legacy CS1-B/DS1-B switches. The 40 mm adjust window is ideal if your extend stroke needs on-site tuning between 60 and 100 mm. Mounting options include Basic, FA, LB, and TC using standard ISO 15552 interface dimensions. If your stroke exceeds 300 mm, carefully verify side-load limits to prevent rod binding. Remember, the stop screw sets end position but does not lock the load; for held loads use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X100-40S
- ✓ 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 SIJ100X100-40S FAQ
