This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X160-50, 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 SIJ80X160-50
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X160-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-50
The AirTAC SIJ80X160-50 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 50 mm on-site, yielding a usable 110-160 mm range from the 160 mm nominal maximum. As an end-of-life product, its direct replacement is the SAIJ80X160-50, preserving the original ISO 15552 mounting interface, force, and travel.
The SAIJ successor introduces an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet and cannot accept a sensor. The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-50 Is Used
Variable Depth Drilling
A machining fixture needing field stroke tuning to accommodate multiple drill depths without swapping the entire actuator.
Adjustable Diverter Arm
A conveyor sorting station requiring on-site extend stroke trimming to handle varying package widths dynamically.
Tiered Carton Pusher
A packaging line where the pusher must alter its forward end position to stack cartons into different tier heights.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-50 with the SAIJ80X160-50
To replace the discontinued SIJ80X160-50, order the direct replacement SAIJ80X160-50, which matches the 80 mm bore, 160 mm stroke, 50 mm adjust window, G3/8 port, and FA/LB/TC mountings. Select the 50 mm adjust window when your fixture needs precise 110-160 mm extend tuning on-site. Because this SKU lacks the -S magnet, it cannot host legacy CS1-B/DS1-B sensors; add external detection if required. For strokes of 300 mm or longer, carefully manage side-load moments to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-50
- ✓ 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 SIJ80X160-50 FAQ
Yes, the SIJ80X160-50 is discontinued. The direct replacement is the SAIJ80X160-50, which shares the identical ISO 15552 interface, 160 mm stroke, 50 mm adjust window, and G3/8 port.
The external stop screw offers a 50 mm trim window, allowing the extend stroke to be shortened from the 160 mm maximum down to 110 mm on-site.
