This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X200-50, 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 SIJ80X200-50
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X200-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-50
The AirTAC SIJ80X200-50 is a discontinued double-acting double-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 150-200 mm window from the 200 mm nominal maximum. The direct replacement is the SAIJ80X200-50, matching the interface, stroke, force, and mounting.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. This SKU lacks a -S magnet and cannot take a switch.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-50 Is Used
Variable Depth Forming Press
Dial in the exact 150-200 mm extend position on-site to accommodate different material thicknesses without swapping the entire actuator.
Adjustable Transfer Diverter
Tune the extend stop by up to 50 mm to cleanly route varying package sizes onto secondary conveyor lines without reprogramming.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-50 with the SAIJ80X200-50
To replace the SIJ80X200-50, order the direct replacement SAIJ80X200-50 (insert A after S), reusing your FA, LB, or TC ISO 15552 mounts. The -50 adjust window provides a 150-200 mm extend range; choose a smaller window if you need finer end-position resolution. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external sensing if required. For strokes of 300 mm or longer, verify side-load guide capacity to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-50
- ✓ 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 SIJ80X200-50 FAQ
Yes, the SIJ80X200-50 is discontinued. The direct replacement is the SAIJ80X200-50, offering the same ISO 15552 interface, 80 mm bore, 200 mm stroke, 50 mm adjust window, and G3/8 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw window is 50 mm, allowing the extend stroke to be shortened from 200 mm down to 150 mm on-site. The stop sets end position only; it is not a load lock.
