This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X160-20, 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 SIJ80X160-20
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20 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 SAIJ80X160-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20
The AirTAC SIJ80X160-20 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 20 mm on-site, yielding a usable 140-160 mm window from the 160 mm nominal maximum. The direct replacement is the SAIJ80X160-20, matching the interface, bore, stroke, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S) and cannot accept a sensor; the stop screw sets end position but is not a load lock, so use an external rod lock for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20 Is Used
Press Fit Tuning
Allows operators to fine-tune the 140-160 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke by up to 20 mm to deflect varying package sizes on a conveyor line accurately.
Adjustable End Stop
Provides a field-adjustable physical end position for pallets, letting maintenance tweak the 160 mm stroke without changing cylinders.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-20 with the SAIJ80X160-20
To replace the discontinued SIJ80X160-20, order the direct replacement SAIJ80X160-20, keeping the identical 80 mm bore, 160 mm stroke, 20 mm adjust window, G3/8 port, and FA/LB/TC mountings. Select the 20 mm adjust window if your field stroke tuning requires trimming the extend by up to 20 mm. This non-magnetic SKU cannot take a switch; add the -S suffix if you need legacy CS1-B/DS1-B sensor accuracy. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The external stop sets end position but does not hold loads on air loss—use SAIL or BSAI variants if a lock is required.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-20
- ✓ 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 SIJ80X160-20 FAQ
Yes, the SIJ80X160-20 is discontinued. The direct replacement is the SAIJ80X160-20, which matches the ISO 15552 interface, 80 mm bore, 160 mm stroke, 20 mm adjust window, G3/8 port, and mounting hardware.
The external stop screw provides a 20 mm trim window, making the usable extend stroke 140-160 mm. The stop sets end position and is not a load lock.
