This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X1000-10S, 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 SIJ125X1000-10S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10S 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 SAIJ125X1000-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10S
The AirTAC SIJ125X1000-10S 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, giving a usable 990-1000 mm window. This stop sets the end position and is not a load lock.
The direct replacement is the SAIJ125X1000-10S, reusing the same interface and mounts. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise bottoming force for press fits without remachining hard stops.
Transfer Diverter
Adjusting the end position lets operators fine-tune a 990-1000 mm diverter gate reach to match varying pallet widths.
Stacker Alignment
Field stroke tuning accommodates minor height variations in stacking fixtures, ensuring accurate contact without repositioning sensors.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X1000-10S with the SAIJ125X1000-10S
Replace the discontinued SIJ125X1000-10S directly with the SAIJ125X1000-10S, retaining the ISO 15552 mounting interface and G1/2 port. Choose the 10 mm adjust window if you need minor end-position tuning rather than a fixed stop. Mounting options include FA, LB, and TC. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Because stroke is 1000 mm, support the rod against bending and use external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X1000-10S
- ✓ 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 SIJ125X1000-10S FAQ
Yes, the SIJ125X1000-10S is discontinued. The direct replacement is the SAIJ125X1000-10S, offering the same ISO 15552 interface, 125 mm bore, 1000 mm stroke, and G1/2 port. The SAIJ family also adds upgraded piston seals and lock variants like SAIL and BSAI.
The external stop screw window is 10 mm, allowing the extend stroke to be shortened from 1000 mm to 990 mm. The stop sets end position and is not a load lock.
