This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X150-50TC, 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 SIJ80X150-50TC
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-50TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X150-50TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-50TC
The AirTAC SIJ80X150-50TC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a TC mount. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 100-150 mm window from the 150 mm nominal maximum. The direct replacement is the SAIJ80X150-50TC, matching the bore, force, adjust window, and mounting.
The SAIJ successor retains the ISO 15552 mounting interface for direct reuse of your TC brackets and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position only—it is not a load lock.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-50TC Is Used
Variable Stroke Clamping
Ideal for clamping stations where part heights vary, using the 50 mm adjust window to tune the extend stroke on-site without swapping cylinders.
Adjustable Transfer Stops
Deployed as a transfer gate stop on conveyors, allowing operators to shorten the 150 mm extend by up to 50 mm to accommodate different package profiles.
Tunable Sorting Diverters
Used in sorting diverters where the exact extend endpoint must be dialed in during commissioning to prevent downstream collisions.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-50TC with the SAIJ80X150-50TC
To replace the discontinued SIJ80X150-50TC, order the direct replacement SAIJ80X150-50TC, keeping the identical 80 mm bore, 150 mm stroke, 50 mm adjust window, and TC mounting interface. The 50 mm adjust window is ideal if your extend stroke needs on-site tuning between 100 and 150 mm. Because this SKU lacks the -S suffix, it has no magnet and cannot accept legacy CS1-B/DS1-B sensors; add sensing externally if required. For strokes at or above 300 mm, verify your side-load limits to prevent guide wear. Remember the external stop sets end position but does not hold the load on air loss; for held loads use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X150-50TC
- ✓ 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 SIJ80X150-50TC FAQ
Yes, the SIJ80X150-50TC is discontinued. The direct replacement is the SAIJ80X150-50TC, which shares the identical ISO 15552 interface, 80 mm bore, 150 mm stroke, 50 mm adjust window, G3/8 port, and TC mounting. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the 150 mm extend stroke down to 100 mm on-site. The stop sets end position only and is not a load lock.
