This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X40-10, 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 SIJ100X40-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X40-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 40mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X40-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X40-10
The AirTAC SIJ100X40-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 40 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 30-40 mm window. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ100X40-10, matching the interface, force, and port. The SAIJ family uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a -S magnet and cannot take a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X40-10 Is Used
Press Fit Tuning
Dialing in a delicate press fit by trimming the extend stroke up to 10 mm on-site, avoiding hard mechanical stops and ensuring precise component seating.
Transfer Diverter
Adjusting a diverter gate stroke by up to 10 mm to accommodate varying package sizes on the fly without changing the entire cylinder setup.
Sealing Head Adjustment
Fine-tuning the down-stroke of a sealing head to maintain exact contact pressure across different material thicknesses.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X40-10 with the SAIJ100X40-10
To replace the discontinued SIJ100X40-10, order the direct replacement SAIJ100X40-10, reusing your existing FA, LB, or TC ISO 15552 mounts. The 10 mm adjust window is ideal for precise end-position tuning without shims. Because this SKU has no -S magnet, it cannot accept legacy CS1-B or DS1-B sensors. For strokes >=300 mm, verify side-load tolerance. The external stop screw only sets end position; for load holding on air loss, use an external rod lock, pilot-operated check valve, or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X40-10
- ✓ 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 SIJ100X40-10 FAQ
Yes, the SIJ100X40-10 is discontinued. The direct replacement is the SAIJ100X40-10. It shares the identical ISO 15552 interface, 100 mm bore, 40 mm stroke, 10 mm adjust window, G1/2 port, and mounting options. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw provides a 10 mm adjust window, allowing you to shorten the 40 mm nominal extend stroke down to 30 mm. The stop sets end position and is not a load lock.
