This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X200-40SN, 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 SIJ80X200-40SN
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40SN 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 SAIJ80X200-40SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40SN
The AirTAC SIJ80X200-40SN 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 40mm on-site, giving a usable 160-200mm window from the 200mm nominal maximum. The 80mm bore features a G3/8 port, M20x1.5 rod thread, and 36mm adjustable cushions. The direct replacement is the SAIJ80X200-40SN, sharing the same interface, force, and mounting.
The SAIJ successor retains ISO 15552 mounting reuse and adds an upgraded two-piece Y-shaped piston seal for low start-up pressure. The -S magnet supports legacy CS1-B/DS1-B switches, while the -N NBR seal suits -20 to +70C. The stop screw sets end position but is not a lock; use SAIL or an external rod lock for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40SN Is Used
Variable Depth Drilling
Adjustable end-position tuning allows a drill head to hit varying material thicknesses on the fly without swapping cylinders.
Dynamic Package Sorting
Trimming the extend stroke by up to 40mm accommodates different box sizes at a diverting station for precise routing.
Tiered Palletizing
Field stroke tuning adapts the pusher reach for varying pallet layer heights, ensuring accurate placement without retooling.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40SN with the SAIJ80X200-40SN
To replace this discontinued SIJ80X200-40SN, order the exact direct replacement SAIJ80X200-40SN, keeping the 200mm nominal stroke, 40mm adjust window, G3/8 port, and -S/-N options. Choose the 40mm adjust window if your field stroke tuning needs to trim the extend by up to 40mm. FA, LB, and TC mountings are available. The -S magnet enables position sensing. For stroke lengths of 300mm or more, verify side-load constraints to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-40SN
- ✓ 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 SIJ80X200-40SN FAQ
Yes, the SIJ80X200-40SN is discontinued. The direct replacement is the SAIJ80X200-40SN, offering the same ISO 15552 interface, 80mm bore, 200mm stroke, 40mm adjust window, G3/8 port, and mounting compatibility.
The external stop screw allows you to trim the extend stroke by up to 40mm on-site, yielding a 160-200mm usable window. The stop sets end position and is not a load lock.
