This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X170-75, 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 SIJ100X170-75
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X170-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 170mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X170-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X170-75
The AirTAC SIJ100X170-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore and 170mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable forward travel of 95-170mm. The direct replacement is the SAIJ100X170-75, matching the G1/2 port, 25mm rod, and 36mm cushions.
The SAIJ successor retains the ISO 15552 mounting interface for direct reuse of FA, LB, and TC brackets. It upgrades reliability with a two Y-shaped one-way piston seal for low start-up pressure, and introduces SAIL and BSAI lock variants absent in the legacy SI line. Note this SKU lacks a magnet (-S) so it cannot accept position switches.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X170-75 Is Used
Variable Pitch Indexing
Allows on-site tuning of the extend stroke by up to 75mm to dial in exact material feed lengths without swapping the entire cylinder assembly.
Adjustable Transfer Pusher
Provides a 95-170mm extend window to accommodate changing package sizes on a packaging line, using the external stop to set the precise ejection point.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X170-75 with the SAIJ100X170-75
To replace the discontinued SIJ100X170-75, order the SAIJ100X170-75, which is a direct match for the ISO 15552 dimensions, 75mm adjust window, and 170mm nominal stroke. Choose the 75mm stop-screw window if your mechanism requires precise end-position tuning between 95mm and 170mm of extend travel. Mounting options include Basic, FA, LB, and TC attachments. Because this specific SKU lacks the -S magnet, it cannot support legacy CS1-B or DS1-B sensors; confirm if sensing is required. For strokes of 300mm or longer, carefully verify side-load guidance to prevent rod bearing wear. Remember the external stop screw sets the end position but is not a load lock; for held loads use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X170-75
- ✓ 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 SIJ100X170-75 FAQ
Yes, the SIJ100X170-75 is discontinued. The direct replacement is the SAIJ100X170-75. It shares the identical ISO 15552 interface, 100mm bore, 170mm stroke, 75mm adjust window, G1/2 port, and mounting footprint. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw window is 75mm, meaning you can shorten the 170mm nominal extend stroke down to 95mm on-site. The stop sets end position but is not a load lock; the cylinder drifts on air loss. Speed is 30-800mm/s, operating pressure is 0.15-1.0MPa, and the port is G1/2.
