This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-75, 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 SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X200-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75
The AirTAC SIJ63X200-75 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 125-200 mm extension from the 200 mm nominal maximum. The direct replacement is the SAIJ63X200-75, matching the interface, force, and mounting.
The SAIJ successor retains ISO 15552 mounting reuse and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads. This non-magnetic SKU cannot take a switch.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75 Is Used
Variable Pitch Indexing
Adjusting the extend stroke by up to 75 mm on-site allows a single 63 mm bore actuator to drive multiple part lengths without swapping the entire cylinder body.
Transfer Diverter Setup
Fine-tuning the 125-200 mm extend window lets operators dial in the exact pusher distance required to divert varying package sizes on a packaging line.
Pallet Stop Positioning
The external stop screw provides a rigid mechanical end position for pallet stops, easily reconfigured as pallet dimensions change without reprogramming valves.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75 with the SAIJ63X200-75
To replace the discontinued SIJ63X200-75, order the direct replacement SAIJ63X200-75. The 75 mm adjust window is ideal if your exact end position needs on-site tuning between 125 and 200 mm. Mounting options include Basic, FA, LB, and TC brackets. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; add external detection if needed. For strokes of 300 mm or longer, verify side-load constraints to prevent guide wear. The stop screw sets end position but does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-75
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-75 FAQ
Yes, the SIJ63X200-75 is discontinued. The direct replacement is the SAIJ63X200-75, which matches the 63 mm bore, 200 mm stroke, 75 mm adjust window, G3/8 port, and ISO 15552 mounting interface. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw allows trimming the extend stroke by up to 75 mm on-site, giving a usable extension range of 125-200 mm. The stop sets end position and is not a load lock.
