This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X400-10, 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 SIJ100X400-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X400-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 400mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X400-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X400-10
The AirTAC SIJ100X400-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 390-400 mm stroke from the 400 mm nominal maximum. The 100 mm bore utilizes a G1/2 port, Ø25 mm rod, and 36 mm adjustable air cushions.
The direct replacement is the SAIJ100X400-10, retaining the ISO 15552 mounting interface, force, and porting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position only—it is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X400-10 Is Used
Press Fit Tuning
Final insertion of a 200 kg assembly requiring a 390-400 mm extend, where the 10 mm stop screw allows precise endpoint calibration without reprogramming the PLC.
Divertor Endpoint Setup
Actuating a diverting arm on a G1/2 ported pneumatic line where a 10 mm field adjustment accommodates minor product size variations at the 400 mm travel limit.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X400-10 with the SAIJ100X400-10
To replace this discontinued SIJ100X400-10, order the direct replacement SAIJ100X400-10, matching the 100 mm bore, 400 mm stroke, and 10 mm adjust window. Choose the 10 mm adjust window only if you need minor on-site extend tuning; for larger trims, select a bigger adjust suffix. Mounting hardware (FA, LB, TC) reuses the ISO 15552 interface. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. Finally, at 400 mm stroke, verify external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X400-10
- ✓ 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 SIJ100X400-10 FAQ
Yes, the SIJ100X400-10 is discontinued. The direct replacement is the SAIJ100X400-10. It shares the identical ISO 15552 interface, 100 mm bore, 400 mm stroke, 10 mm adjust window, G1/2 port, and force ratings. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure.
The external stop screw provides a 10 mm adjust window, allowing you to trim the 400 mm extend stroke down to 390 mm on-site. The stop sets end position only; it is not a load lock.
