This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X75-10S, 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 SIJ125X75-10S
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X75-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X75-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X75-10S
The AirTAC SIJ125X75-10S 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 65-75 mm stroke from the 75 mm nominal maximum. The direct replacement is the SAIJ125X75-10S, matching the interface, force, and mounting.
The SAIJ successor retains ISO 15552 mounting interchangeability and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. The stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X75-10S Is Used
Press Fit Calibration
Needs field stroke tuning to dial in the exact 65-75 mm insertion depth of a bearing without swapping cylinders.
Divertor Gate Adjustment
Requires trimming the extend stroke by up to 10 mm on-site to alter the package redirect angle on the fly.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X75-10S with the SAIJ125X75-10S
To replace the discontinued SIJ125X75-10S, order the direct replacement SAIJ125X75-10S, which preserves the 75 mm maximum stroke, 10 mm adjust window, G1/2 port, and 32 mm rod. Choose the 10 mm adjust window if you need precise 65-75 mm extend tuning. FA, LB, and TC mountings are supported. The -S magnet enables position sensing. For stroke lengths of 300 mm or greater, carefully evaluate rod side-load deflection.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X75-10S
- ✓ 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 SIJ125X75-10S FAQ
Yes, the SIJ125X75-10S is discontinued. The direct replacement is the SAIJ125X75-10S. It matches the ISO 15552 interface, 125 mm bore, 75 mm stroke, 10 mm adjust window, and G1/2 port. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw window is 10 mm, allowing you to shorten the 75 mm nominal extend stroke down to 65 mm. This stop sets the end position and is not a load lock.
