This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X160-75, 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 SIJ63 Double Rod Adjustable Cylinder SIJ63X160-75
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X160-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X160-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X160-75
The AirTAC SIJ63X160-75 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 75 mm on-site, giving a usable forward range of 85-160 mm (the 160 mm nominal stroke is the maximum).
Because this SIJ model is end-of-life, the direct replacement is the SAIJ63X160-75—identical ISO 15552 mounting interface, bore, force, and adjust window. The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note: this SKU lacks a -S magnet and cannot accept a sensor; the stop screw sets end position but is not a load lock.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X160-75 Is Used
Press Fit Tuning
Allows operators to dial in the exact 85-160 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke up to 75 mm to deflect different package sizes on a line, ensuring precise routing.
Adjustable End Stop
Sets a specific physical end position for pallets or racks in a 63 mm bore actuator, fine-tuned during commissioning.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X160-75 with the SAIJ63X160-75
To replace the discontinued SIJ63X160-75, order the SAIJ63X160-75 direct: it preserves the 75 mm adjust window, 160 mm max stroke, G3/8 port, and FA/LB/TC mountings. Choose the adjust window based on your on-site stroke-trim needs (here, shortening extend by up to 75 mm). Because this SKU has no -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load tolerance. Remember the external stop sets end position only; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X160-75
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X160-75 FAQ
Yes, the SIJ63X160-75 is discontinued. The direct replacement is the SAIJ63X160-75. It shares the same ISO 15552 interface, 63 mm bore, 160 mm stroke, 75 mm adjust window, G3/8 port, and mounting options, but adds an upgraded SAI piston seal.
The external stop screw window is 75 mm, allowing you to trim the extend stroke from the 160 mm maximum down to 85 mm. The stop sets end position but is not a load lock.
