This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X250-100S, 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 SIJ32X250-100S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 250mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X250-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100S
The AirTAC SIJ32X250-100S 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 100 mm on-site, giving a usable 150-250 mm extension out of the 250 mm nominal maximum.
The direct replacement is the SAIJ32X250-100S, matching the ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade utilizes a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 100 mm to push parts of varying widths into a machining station without swapping cylinders.
Adjustable Diverter Gate
Setting a precise 150 to 250 mm extension to deflect different package sizes on a conveyor line, accommodating product changes.
Variable Depth Sealing
Trimming the extend stroke to press seals onto cartons of varying depths, ensuring consistent contact pressure.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-100S with the SAIJ32X250-100S
To replace the discontinued SIJ32X250-100S, order the exact direct replacement SAIJ32X250-100S. The 100 mm adjust window allows field tuning of the extend stroke from 150 to 250 mm. Mounting reuses ISO 15552 basic, FA, LB, or TC attachments. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (current AirTAC switches are used on the SAIJ). For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X250-100S
- ✓ 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 SIJ32X250-100S FAQ
Yes, the SIJ32X250-100S is discontinued. The direct replacement is the SAIJ32X250-100S, which matches the ISO 15552 interface, 32 mm bore, 250 mm stroke, 100 mm adjust window, and G1/8 port. The SAIJ family uses an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw allows trimming the extend stroke by up to 100 mm on-site (usable extension 150-250 mm). The stop sets end position and is not a load lock; use an external rod lock or SAIL/BSAI variant for load holding.
