This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X1000-40, 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 SIJ63X1000-40
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X1000-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-40
The AirTAC SIJ63X1000-40 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 40 mm on-site, yielding a usable 960-1000 mm stroke from the 1000 mm nominal maximum. Because this SKU lacks a -S magnet, it cannot accept a magnetic switch.
As SIJ is end-of-life, the direct replacement is the SAIJ63X1000-40, preserving the same ISO 15552 mounting interface, bore, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note that the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-40 Is Used
Long-Transfer Pusher
Pushes parts down a 1000 mm conveyor lane, using the 40 mm external stop screw to fine-tune the extend endpoint precisely to the gate location.
Variable-Depth Pallet Stop
Acts as a physical stop for pallets of varying widths, trimming the extend stroke on-site by up to 40 mm to accommodate different load depths.
Long-Stroke Forming Press
Provides a 960-1000 mm extend stroke for deep-draw forming, allowing operators to dial in the exact bottom dead center without reprogramming the motion controller.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-40 with the SAIJ63X1000-40
To replace the discontinued SIJ63X1000-40, order the direct replacement SAIJ63X1000-40, keeping the identical 40 mm adjust window and ISO 15552 footprint. Choose your mounting from Basic, FA, LB, or TC options. This non-magnetic SKU cannot support sensors; if position detection is needed, select a -S magnet model (compatible with legacy CS1-B/DS1-B switches). Because the 1000 mm stroke is long, minimize side-load and rod-bending by using an external guide to support the rod. The stop screw merely sets the end position and does not lock the load; for load holding without live air, use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X1000-40
- ✓ 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 SIJ63X1000-40 FAQ
Yes, the SIJ63X1000-40 is discontinued. The direct replacement is the SAIJ63X1000-40, which shares the same ISO 15552 interface, 63 mm bore, 1000 mm stroke, 40 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the 1000 mm extend stroke down to 960 mm on-site. The stop sets end position only and is not a load lock.
