This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X100-20TC, 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 SIJ32X100-20TC
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X100-20TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X100-20TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-20TC
The AirTAC SIJ32X100-20TC is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, discontinued and replaced by the SAIJ32X100-20TC. The external stop screw lets you trim the extend stroke by up to 20mm on-site, giving a usable 80-100mm window from the 100mm nominal maximum.
The direct replacement SAIJ32X100-20TC shares the exact ISO 15552 interface, TC mount, and force, but upgrades to a two Y-shaped one-way piston seal for lower start-up pressure. The stop sets end position only; it is not a load lock, so use SAIL or an external rod lock to hold loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-20TC Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 20mm on-site allows precise 80-100mm gate travel without machining spacers.
Variable Carton Sealing
The TC mount and adjustable stop let operators dial in exact flap contact pressure within the 100mm window.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-20TC with the SAIJ32X100-20TC
Replace the discontinued SIJ32X100-20TC directly with the SAIJ32X100-20TC, retaining the TC mount and G1/8 port. The -20mm adjust window is ideal if your extend target sits between 80-100mm. This non-magnetic SKU lacks a -S sensor piston and cannot take a switch. For stroke lengths >=300mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X100-20TC
- ✓ 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 SIJ32X100-20TC FAQ
Yes, the SIJ32X100-20TC is discontinued. The direct replacement is the SAIJ32X100-20TC, sharing the same ISO 15552 interface, TC mount, 100mm stroke, 20mm adjust window, and G1/8 port.
The external stop screw trims the extend stroke by up to 20mm on-site, yielding an 80-100mm usable window. The stop sets end position and is not a load lock.
