This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X450-100S, 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 SIJ32X450-100S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X450-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100S
The AirTAC SIJ32X450-100S 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, yielding a usable 350-450 mm extension from the 450 mm nominal maximum. The direct replacement is the SAIJ32X450-100S, preserving the interface, force, and mounting.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100S Is Used
Variable Pitch Pushing
Allows operators to dial in the extend stroke from 350 to 450 mm on-site to push parts of varying widths into a machining station without swapping cylinders.
Adjustable Diverter Arm
An external stop screw sets the exact reach of a sorting arm over the conveyor, enabling quick field tuning when product sizes change.
Variable Depth Sealing
Provides adjustable end-position control for a sealing head that must compress packages of different heights within a 100 mm range.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100S with the SAIJ32X450-100S
To replace the discontinued SIJ32X450-100S, order the direct replacement SAIJ32X450-100S, which retains the 32 mm bore, 450 mm max stroke, 100 mm adjust window, G1/8 port, and FA/LB/TC mountings. Choose the 100 mm adjust window if you need to trim the extend stroke on-site from 450 mm down to 350 mm. The -S suffix confirms a piston magnet for switch sensing. Because the 450 mm stroke is long, verify side-load conditions and use external guides to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X450-100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
