This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X600-30, 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.

The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X600-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X600-30, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ100X600-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. It features a 100mm bore, a 600mm maximum extend stroke, and an external stop screw that lets you trim the extend stroke by up to 30mm on-site, yielding a usable 570-600mm stroke. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ100X600-30, retaining the same interface, bore, stroke, force, port, and mounting. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note this SKU lacks a -S magnet and cannot take a switch; loads are not held on air loss without an external rod lock.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Final insertion depth of a bearing requires field adjustment. The 30mm stop screw window trims the 600mm extend stroke precisely without remounting the actuator.
A diverting gate on a conveyor needs to hit different product sizes. The external stop sets the exact extend position on-site for each run.
Packaging equipment folding carton flaps of varying heights uses the adjustable stroke to set the final fold position accurately on the fly.
The 30mm adjust window is ideal if you need to fine-tune the extend end position between 570 and 600mm without machining. Mounting interfaces include Basic, FA, LB, and TC. Because the 600mm stroke is long, use external guides to prevent rod bending and manage side loads. This non-magnetic SKU cannot accept a sensor; for position feedback you need the -S variant. For load holding on air loss, use an external rod lock or check valve, as the stop screw is not a brake.
Replacement checklist
Yes, the SIJ100X600-30 is discontinued. The direct replacement is the SAIJ100X600-30. It shares the same ISO 15552 interface, 100mm bore, 600mm stroke, 30mm adjust window, G1/2 port, and mounting, but adds an upgraded Y-shaped piston seal.
The external stop screw window is 30mm, allowing you to shorten the 600mm extend stroke down to 570mm on-site. The stop sets end position only; it is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ100X600-30 replacement — usually within 7-8 hours.
