This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X15-10, 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 SIJ63X15-10
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X15-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 15mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X15-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X15-10
The AirTAC SIJ63X15-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the direct replacement SAIJ63X15-10. It uses an external stop screw to trim the extend stroke by up to 10 mm on-site, yielding a usable 5-15 mm extend window from the 15 mm nominal maximum.
The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL variant for held loads. This non-magnet SKU cannot take a switch. The SAIJ upgrade uses two Y-shaped piston seals for low start-up pressure.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X15-10 Is Used
Short-Stroke Clamping
Acts as a precision clamp where the exact jaw closure point must be dialed in on-site, using the 10 mm adjust screw to accommodate varying material thicknesses without re-plumbing the G3/8 air lines.
Transfer Diverter Setup
Tunes the extend distance of a diverter gate on a packaging line, allowing operators to shorten the 15 mm nominal stroke by up to 10 mm to perfectly meet changing product profiles.
Actuator End-Position Trimming
Provides a mechanical stop for low-impact end positions in testing fixtures, giving a 5-15 mm usable extend window where a fixed 15 mm stroke would otherwise overrun a delicate workpiece.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X15-10 with the SAIJ63X15-10
To replace the discontinued SIJ63X15-10, order the exact direct replacement SAIJ63X15-10, reusing your ISO 15552 FA, LB, or TC mounts. The 10 mm adjust window lets you tune the extend end-position on-site (5-15 mm usable stroke), but remember it sets position rather than locking the load. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external physical stops if detection is required. Side-load alignment is less critical for this short 15 mm stroke, but always verify rod-end threading (M16x1.5) and G3/8 porting match your existing plumbing.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X15-10
- ✓ 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 SIJ63X15-10 FAQ
Yes, the SIJ63X15-10 is discontinued. The direct replacement is the SAIJ63X15-10, which shares the identical ISO 15552 interface, 63 mm bore, 15 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw allows you to trim the extend stroke by up to 10 mm on-site, creating a 5-15 mm usable extend window from the 15 mm nominal maximum. The stop sets the end position and is not a load lock.
