This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X80-10, 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 SIJ125X80-10
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X80-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X80-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X80-10
The AirTAC SIJ125X80-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 70-80 mm extend out of the 80 mm nominal maximum. The direct replacement is the SAIJ125X80-10, matching the interface, force, and mounting.
The SAIJ successor retains the dimensions but adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; use SAIL or BSAI variants for held loads.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X80-10 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise bottoming force for pressing bearings without machining hard stops.
Divertor Gate Adjustment
Field-tuning the 70-80 mm extend stroke lets operators fine-tune package diverter gate clearance on the line.
Pallet Stop Positioning
Adjusting the end position on-site accommodates varying pallet footprints without swapping the entire cylinder assembly.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X80-10 with the SAIJ125X80-10
To replace the discontinued SIJ125X80-10, specify SAIJ125X80-10 for an exact ISO 15552 direct match. Choose the 10 mm adjust window if you only need minor end-position tuning. Reuse FA, LB, or TC mounts directly. This SKU lacks the -S magnet and cannot take a switch. For strokes of 300 mm or longer, verify side-load guidance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X80-10
- ✓ 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 SIJ125X80-10 FAQ
Yes, the SIJ125X80-10 is discontinued. The direct replacement is the SAIJ125X80-10, which matches the ISO 15552 interface, 80 mm stroke, 10 mm adjust window, and G1/2 port.
The external stop screw trims the extend stroke by up to 10 mm on-site (usable 70-80 mm). It sets end position and is not a load lock.
