This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X175-30, 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.
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-30
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X175-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X175-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-30
The AirTAC SIJ100X175-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 175 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable extend range of 145-175 mm; the stop sets the end position and is not a load lock. The genuine ISO 15552 interface means you reuse your existing FA, LB or TC mounting dimensions without re-drilling.
The direct replacement is the SAIJ100X175-30, matching the bore, stroke, adjust window, force and port. The SAIJ family uses an upgraded two-piece Y-shaped one-way piston seal for lower start-up pressure and longer life. Because this SKU lacks the -S suffix, it has no magnet and cannot take a reed or solid-state switch. A plain cylinder drifts on air loss; for held loads use an external rod lock or the SAIL/BSAI lock variant.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-30 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 30 mm on-site allows operators to dial in the exact insertion depth for bearing or bushing press fits without machining a custom-length rod.
Variable Length Diverter
An external stop screw lets a sorting diverter accommodate different package lengths on the fly, shortening the extend stroke from the 175 mm maximum down to 145 mm as needed.
Adjustable End Stop Pusher
A pallet positioning pusher uses the 30 mm adjust window to compensate for product width variations, setting a precise end position while reusing the existing ISO 15552 TC mount.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-30 with the SAIJ100X175-30
To replace the discontinued SIJ100X175-30, order the direct replacement SAIJ100X175-30, which preserves the 100 mm bore, 175 mm nominal stroke, 30 mm adjust window, G1/2 port and ISO 15552 mounting interface. Choose the 30 mm adjust window when you need to fine-tune the extend end position between 145 and 175 mm on-site; the external stop screw sets the end position but does not lock the load. Mounting options include Basic, FA, LB and TC; because this is a non-magnetic SKU (no -S suffix), it cannot accept a position sensor. For strokes of 300 mm or longer, verify side-load limits to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X175-30
- ✓ 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 SIJ100X175-30 FAQ
Yes, the SIJ100X175-30 is discontinued. The direct replacement is the SAIJ100X175-30. It matches the 100 mm bore, 175 mm stroke, 30 mm adjust window, G1/2 port and ISO 15552 mounting interface, while adding an upgraded two-piece Y-shaped piston seal for longer life.
This double-acting double-rod cylinder has a 30 mm adjust window, allowing you to shorten the 175 mm extend stroke down to 145 mm. The G1/2 port and 36 mm cushions are fixed by the 100 mm bore.
