This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X200-20, 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 SIJ80X200-20
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-20 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 SAIJ80X200-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-20
The AirTAC SIJ80X200-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 200 mm nominal stroke and a 20 mm external stop screw window, letting you trim the extend stroke on-site down to 180 mm. The direct replacement is the SAIJ80X200-20, matching the interface, force, and mounting.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot accept a switch, and the stop screw sets end position only—it is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-20 Is Used
Press Fit Calibration
Fine-tune the extend stroke by up to 20 mm on-site to dial in exact press-fit depths for bearings without machining custom spacers.
Variable Length Diverter
Adjust the extend stop within the 180-200 mm window to deflect varying package sizes on a conveyor line accurately.
Adjustable End Stop
Set precise end positions for pallet stops, allowing 20 mm of field flexibility to accommodate different pallet footprints.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-20 with the SAIJ80X200-20
To replace the discontinued SIJ80X200-20, order the exact direct replacement SAIJ80X200-20, keeping the 200 mm nominal stroke and 20 mm adjust window (180-200 mm usable extend). Mounting interfaces (Basic, FA, LB, TC) are fully reusable. This SKU lacks the -S magnet and cannot take a sensor; if position detection is needed, select a -S model. For strokes at or over 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-20
- ✓ 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 SIJ80X200-20 FAQ
Yes, the SIJ80X200-20 is discontinued. The direct replacement is the SAIJ80X200-20, offering the same ISO 15552 interface, 80 mm bore, 200 mm stroke, 20 mm adjust window, G3/8 port, and mounting options.
The external stop screw window is 20 mm, allowing the extend stroke to be shortened on-site from 200 mm down to 180 mm.
