This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X150-100, 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 SIJ100X150-100 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 SAIJ100X150-100, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ100X150-100 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 100 mm on-site, giving a usable 50-150 mm window from the 150 mm nominal maximum. It features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a fixed G1/2 port.
As this SIJ model is end-of-life, the direct replacement is the SAIJ100X150-100, retaining the same interface, force, and adjustability. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet, so it cannot take a switch; the stop sets position but is not a load lock.

The SAIJ100X150-100 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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).
Allows operators to fine-tune the extend stroke on-site for pressing bearings, ensuring exact insertion depth without swapping cylinders.
Adjusts the extend position of a routing gate on a conveyor to handle changing package sizes on the fly.
Provides a field-adjustable hard stop for pallet positioning, trimming the extend stroke up to 100 mm to accommodate different pallet heights.
To replace the discontinued SIJ100X150-100, order the direct replacement SAIJ100X150-100, which matches the 100 mm bore, 150 mm stroke, 100 mm adjust window, and G1/2 port. Choose the 100 mm adjust window if you need to trim the extend stroke anywhere from 50 to 150 mm on-site. Mounting reuses ISO 15552 interface dimensions (Basic, FA, LB, TC). Because this SKU has no -S magnet, it cannot accept a sensor; for sensing, select an -S model (legacy CS1-B/DS1-B accuracy). For strokes >=300 mm, verify side-load tolerance. The stop screw sets end position only; it is not a lock, and a plain cylinder drifts on air loss—use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
Yes, the SIJ100X150-100 is discontinued. The direct replacement is the SAIJ100X150-100. It shares the same ISO 15552 interface, 100 mm bore, 150 mm stroke, 100 mm adjust window, and G1/2 port, but adds an upgraded two Y-shaped one-way piston seal.
The external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 50-150 mm window. 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 SAIJ100X150-100 replacement — usually within 7-8 hours.
