This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X150-10S, 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 SIJ100X150-10S 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 SAIJ100X150-10S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ100X150-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and G1/2 port. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 140-150 mm extend out of the 150 mm nominal maximum. The stop sets the end position; it is not a load lock.
The direct replacement is the SAIJ100X150-10S, sharing the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.

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).
Field-trim the extend stroke by up to 10 mm to set precise press depths for bearing insertion without machining hard stops.
Adjust the extend end position on-site to align pusher plates with varying product sizes on a packaging line.
Fine-tune the 150 mm extend stroke to act as a physical stop for pallets, allowing 10 mm of flexibility for height variations.
To replace the discontinued SIJ100X150-10S, order the exact direct replacement SAIJ100X150-10S. Mounting options include Basic, FA, LB, and TC using genuine ISO 15552 interface dimensions. The -S suffix confirms the piston magnet is present. For stroke lengths of 300 mm or greater, verify side-load constraints to prevent rod binding.
Replacement checklist
Yes, the SIJ100X150-10S is discontinued. The direct replacement is the SAIJ100X150-10S. It shares the same ISO 15552 interface, 100 mm bore, 150 mm stroke, 10 mm adjust window, and G1/2 port. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The 10 mm external stop screw window allows a usable extend stroke of 140-150 mm (nominal 150 mm is the maximum). The stop sets end position and is not a load lock; use an external rod lock for held loads.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ100X150-10S replacement — usually within 7-8 hours.
