This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X110-40S, 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 SIJ63X110-40S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X110-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 110mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X110-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X110-40S
The AirTAC SIJ63X110-40S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 110 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 70-110 mm window. As a direct, the SAIJ63X110-40S shares the exact ISO 15552 mounting interface, bore, force, and adjust window.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. 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. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X110-40S Is Used
Press Fit Depth Tuning
Dialing in exact insertion depths for bearing presses. The 40 mm adjust window allows operators to fine-tune the extend stroke on-site without swapping cylinders.
Variable Length Diverter
Routing packages of varying sizes on a sorting line. The external stop screw shortens the extend stroke to match specific product dimensions on the fly.
Adjustable End Stop Pusher
Positioning pallets at different staging distances. The cylinder provides a 70-110 mm extend window to accommodate changing layout requirements.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X110-40S with the SAIJ63X110-40S
To replace the discontinued SIJ63X110-40S, order the direct replacement SAIJ63X110-40S, which preserves the 63 mm bore, 110 mm nominal stroke, 40 mm adjust window, G3/8 port, and FA/LB/TC mountings. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 70 and 110 mm. The -S suffix ensures a built-in magnet for position sensing. For strokes of 300 mm or longer, verify side-load calculations to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X110-40S
- ✓ 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 SIJ63X110-40S FAQ
Yes, the SIJ63X110-40S is discontinued. The direct replacement is the SAIJ63X110-40S. It shares the identical ISO 15552 interface, 63 mm bore, 110 mm stroke, 40 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw offers a 40 mm adjust window, allowing the extend stroke to be shortened from the 110 mm maximum down to 70 mm. The stop sets end position and is not a load lock.
