This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X150-10S, 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 SIJ63X150-10S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X150-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X150-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-10S
The AirTAC SIJ63X150-10S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The direct replacement is the SAIJ63X150-10S, retaining the 63 mm bore, 150 mm nominal stroke, G3/8 port, and 10 mm adjust window. An external stop screw lets you trim the extend stroke by up to 10 mm on-site (usable extend 140-150 mm). The stop sets the end position and is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-10S Is Used
Press Fit Calibration
Trimming the extend stroke by up to 10 mm on-site allows operators to fine-tune press fit depth without machining custom spacers.
Transfer Stop Positioning
Adjusting the end position lets maintenance teams shift a conveyor stop block by a few millimeters to accommodate product width changes.
Sealing Head Depth
Field adjustment of the extend stroke provides precise control over sealing head contact depth on varying package heights.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-10S with the SAIJ63X150-10S
To replace the discontinued SIJ63X150-10S, specify SAIJ63X150-10S for an exact ISO 15552 direct with identical 10 mm adjust window. Choose the 10 mm adjust window when you need minor field tuning of the extend position. Mounting interfaces include Basic, FA, LB, and TC. The -S option provides a piston magnet for legacy CS1-B/DS1-B switches (current AirTAC switches are used on the SAIJ). For stroke lengths of 300 mm or more, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X150-10S
- ✓ 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 SIJ63X150-10S FAQ
Yes, the SIJ63X150-10S is discontinued. The direct replacement is the SAIJ63X150-10S. It shares the same ISO 15552 interface, 63 mm bore, 150 mm stroke, G3/8 port, and 10 mm adjust window. The SAIJ upgrade uses an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw window is 10 mm, allowing you to shorten the extend stroke from the 150 mm maximum down to 140 mm. The stop sets end position only; it is not a load lock.
