This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X100-50TC, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X100-50TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC
The AirTAC SIJ80X100-50TC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 50-100 mm window. The stop sets the end position; it is not a load lock.
The direct replacement is the SAIJ80X100-50TC, retaining the same ISO 15552 interface, TC mounting, and force. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a -S magnet and cannot take a switch.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC Is Used
Variable Stroke Pressing
Trimming the extend stroke by up to 50 mm on-site allows precise positioning for pressing operations without machining custom spacers.
Adjustable Diverter Arm
A TC-mounted diverter can be tuned between 50 and 100 mm to accommodate different package sizes on a sorting line.
Variable Depth Pallet Stop
External stop screw adjustment allows operators to change the extend end position for varying pallet depths quickly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC with the SAIJ80X100-50TC
To replace the discontinued SIJ80X100-50TC, order the direct replacement SAIJ80X100-50TC, which preserves the 80 mm bore, 100 mm stroke, 50 mm adjust window, G3/8 port, and TC mount. Choose the 50 mm adjust window if your extend stroke needs on-site tuning between 50 and 100 mm. The TC mount provides a rear clevis interface. Because this SKU has no -S magnet, it cannot accept a sensor; for sensing use a -S model. For strokes >=300 mm, verify side-load limits to prevent rod binding. A plain cylinder does not hold loads on air loss; for held loads use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-50TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-50TC FAQ
Yes, the SIJ80X100-50TC is discontinued. The direct replacement is the SAIJ80X100-50TC. It shares the identical ISO 15552 interface, 80 mm bore, 100 mm nominal stroke, 50 mm adjust window, G3/8 port, and TC mount, while adding an upgraded SAI piston seal.
The external stop screw provides a 50 mm adjust window, allowing the 100 mm extend stroke to be shortened on-site down to 50 mm. The stop sets end position and is not a load lock.
