This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X600-10S, 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 SIJ125X600-10S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X600-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X600-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X600-10S
The AirTAC SIJ125X600-10S 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 10 mm on-site, yielding a usable 590-600 mm stroke. It features a 125 mm bore, G1/2 port, M27x2 rod thread, and 40 mm adjustable cushions. The direct replacement is the SAIJ125X600-10S.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure. The stop sets end position, not a load lock.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X600-10S Is Used
Press Fit Tuning
Final press depth requires micro-adjustments on-site. The 10 mm stop screw window trims the extend stroke to dial in the exact insertion point without remounting.
Divertor Gate Positioning
Adjusting the divertor flap reach to handle varying package sizes. The external stop screw sets the precise 590-600 mm extend end position for reliable routing.
Pallet Stop Alignment
Calibrating the physical stop location for different pallet depths. The adjustable stroke window allows operators to shorten the extend stroke by up to 10 mm on-site.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X600-10S with the SAIJ125X600-10S
To replace the discontinued SIJ125X600-10S, use the direct replacement SAIJ125X600-10S, reusing the exact ISO 15552 mounting interface. The 10 mm adjust window allows fine-tuning the extend end position without shims. Mounting options include FA, LB, and TC. The -S suffix includes a piston magnet for legacy CS1-B/DS1-B switches. For the 600 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X600-10S
- ✓ 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 SIJ125X600-10S FAQ
Yes, the SIJ125X600-10S is discontinued. The direct replacement is the SAIJ125X600-10S, offering the same ISO 15552 interface, 125 mm bore, 600 mm stroke, G1/2 port, and 10 mm adjust window.
The external stop screw window is 10 mm, shortening the extend stroke from 600 mm down to 590 mm.
