This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X55-10S, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X55-10S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X55-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 55mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X55-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X55-10S
The AirTAC SIJ32X55-10S 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 45-55 mm window from the 55 mm nominal maximum. The stop sets the end position but is not a load lock. The bore 32 mm variant features a 12 mm rod, M10x1.25 thread, 27 mm adjustable cushions, G1/8 port, and 30-800 mm/s speed.
The direct replacement is the SAIJ32X55-10S, matching the ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X55-10S Is Used
Short-Stroke Clamping
Clamping parts where material thickness varies slightly, using the 10 mm adjust screw to tune the 55 mm extend stroke precisely on-site without changing mounts.
Sensor Positioning
Adjusting the end position of a 32 mm bore probe actuator within a 45-55 mm window to accommodate different product heights on a single ISO 15552 fixture.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X55-10S with the SAIJ32X55-10S
To replace the discontinued SIJ32X55-10S, order the direct replacement SAIJ32X55-10S, keeping the same 32 mm bore, 55 mm stroke, 10 mm adjust window, and G1/8 port. Choose the 10 mm adjust window when you need on-site extend tuning between 45-55 mm. Reuse FA, LB, or TC mounts via the ISO 15552 interface. The -S magnet ensures legacy CS1-B/DS1-B sensor compatibility. Because the 55 mm stroke is under 300 mm, side-load rod deflection is minimal. The stop screw sets end position only; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X55-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X55-10S FAQ
Yes, the SIJ32X55-10S is discontinued. The direct replacement is the SAIJ32X55-10S. It shares the same ISO 15552 interface, 32 mm bore, 55 mm stroke, 10 mm adjust window, G1/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal.
The external stop screw window is 10 mm, allowing you to trim the 55 mm nominal extend stroke down to 45 mm on-site. The stop sets end position and is not a load lock.
