This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X150-100S, 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 SIJ100X150-100S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X150-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X150-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-100S
The AirTAC SIJ100X150-100S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore and G1/2 port. An external stop screw lets you trim the extend stroke by up to 100mm on-site, giving a usable 50-150mm window from the 150mm nominal maximum. The direct replacement is the SAIJ100X150-100S, sharing the same interface, force, and mounting.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note the stop screw 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 SIJ100X150-100S Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning from 50 to 150mm to handle changing product lengths without swapping the entire actuator assembly.
Adjustable Carton Sealing
Provides field stroke trimming for varying package heights, ensuring precise end-positioning without re-engineering fixed hard stops.
Custom Forming Stops
Enables operators to dial in the exact 100mm extend reduction on-site for prototype metal forming runs before finalizing tooling.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-100S with the SAIJ100X150-100S
To replace the discontinued SIJ100X150-100S, order the direct replacement SAIJ100X150-100S, retaining the same ISO 15552 mounting interface (Basic, FA, LB, TC) and G1/2 port. Choose the 100mm adjust window when you need on-site flexibility to shorten the extend stroke from 150mm down to 50mm. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For strokes at or above 300mm, verify side-load limits to prevent excessive guide wear. Remember the stop screw sets end position but does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X150-100S
- ✓ 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 SIJ100X150-100S FAQ
Yes, the SIJ100X150-100S is discontinued. The direct replacement is the SAIJ100X150-100S, which shares the same ISO 15552 interface, 100mm bore, 150mm stroke, 100mm adjust window, G1/2 port, and mounting options. The SAIJ upgrade features an improved two Y-shaped one-way piston seal for longer life.
The external stop screw window is 100mm, allowing you to trim the extend stroke on-site from the 150mm nominal maximum down to 50mm. The stop sets end position only and is not a load lock.
