This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X150-100S, 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 SIJ32X150-100S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X150-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X150-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-100S
The AirTAC SIJ32X150-100S 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 50-150 mm stroke from the 150 mm nominal maximum.
The direct replacement is the SAIJ32X150-100S, retaining the same interface, force, and adjust window. The SAIJ upgrade introduces a two-piece Y-shaped 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 SIJ32X150-100S Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to regulate drill depth precisely without swapping the entire cylinder.
Variable Length Diverter
Tunes the pusher extension to deflect varying package sizes on a packaging line.
Adjustable Stop Gate
Modifies the extend stroke to act as a physical stop for different pallet widths.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-100S with the SAIJ32X150-100S
To replace the discontinued SIJ32X150-100S, order the direct replacement SAIJ32X150-100S, which preserves the ISO 15552 mounting dimensions, G1/8 port, and 100 mm adjust window. Choose the 100 mm adjust window if your application requires on-site tuning of the extend stroke from 50 to 150 mm. Mounting attachments (FA, LB, TC) reuse standard ISO 15552 interfaces. The -S suffix ensures piston magnet readiness for switches. For strokes of 300 mm or longer, verify side-load constraints to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X150-100S
- ✓ 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 SIJ32X150-100S FAQ
Yes, the AirTAC SIJ32X150-100S is discontinued. The direct replacement is the SAIJ32X150-100S. It shares the same ISO 15552 interface, 32 mm bore, 150 mm stroke, 100 mm adjust window, G1/8 port, and mounting options, while upgrading the piston seal.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from the 150 mm nominal maximum down to 50 mm.
