This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X1000-10, 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 SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 1000mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X1000-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10
The AirTAC SIJ125X1000-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, discontinued and replaced by the exact direct replacement SAIJ125X1000-10. The external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 990-1000 mm range where the 1000 mm nominal stroke is the maximum. It features a 125 mm bore, G1/2 port, M27x2 rod thread, and 40 mm adjustable air cushions. This stop sets the end position but is not a load lock.
The SAIJ upgrade uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure, and the SAI family introduces SAIL and BSAI lock variants the SI line lacked. This non-magnetic SKU cannot take a switch.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10 Is Used
Press Fit Tuning
Final press operations needing exact end-position tweaking within a 10 mm window to compensate for material variance without re-mounting the actuator.
Divertor Adjustment
Sorting diverters requiring precise extend endpoint calibration to hit changing lane widths on the fly using the external stop screw.
Pallet Stop Calibration
Heavy pallet stops where a 10 mm field adjustment aligns the stopping face perfectly to varying pallet geometries.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10 with the SAIJ125X1000-10
To replace the discontinued SIJ125X1000-10, order the direct replacement SAIJ125X1000-10, matching the 125 mm bore, 1000 mm stroke, 10 mm adjust window, G1/2 port, and ISO 15552 mounting. Choose the 10 mm adjust window if you only need micro-trimming of the extend end position. Mounting interfaces include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For the 1000 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X1000-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10 FAQ
Yes, the SIJ125X1000-10 is discontinued. The direct replacement is the SAIJ125X1000-10, sharing the same ISO 15552 interface, 125 mm bore, 1000 mm stroke, 10 mm adjust window, G1/2 port, and mounting options.
The external stop screw trims the extend stroke by up to 10 mm (usable 990-1000 mm). The stop sets end position but is not a load lock; use an external rod lock for held loads.
