This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X20-10S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X20-10S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X20-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 20mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X20-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X20-10S
The AirTAC SIJ100X20-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore and 20mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 10mm on-site (usable range 10-20mm). The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ100X20-10S, reusing the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. A plain cylinder drifts on air loss; for held loads use SAIL/BSAI or an external rod lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X20-10S Is Used
Short-Stroke Clamping
Provides adjustable 10-20mm clamping travel on machining fixtures, allowing operators to fine-tune the exact grip position on varying part profiles.
Precise Pressing Stops
Ideal for light pressing or staking tasks where the extend stroke must be dialed in precisely within a 10mm window to avoid over-travel and workpiece damage.
Component Seating
Used in sub-assembly stations to seat bearings or pins, where the external stop screw sets the final bottoming position independently of pneumatic pressure fluctuations.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X20-10S with the SAIJ100X20-10S
To replace the discontinued SIJ100X20-10S, order the direct replacement SAIJ100X20-10S, keeping the 10mm adjust window and -S magnet for legacy CS1-B/DS1-B switches (SAIJ uses current AirTAC switches). Reuse FA, LB, or TC mounts via the ISO 15552 interface. The 10mm adjust window is ideal for fine end-tuning. Speed is 30-800mm/s. As stroke is under 300mm, side-load guide concerns are minimal. The stop screw sets end position, not a lock; for load holding use an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X20-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X20-10S FAQ
Yes, the SIJ100X20-10S is discontinued. The direct replacement is the SAIJ100X20-10S. It shares the same 100mm bore, 20mm nominal stroke, 10mm adjust window, G1/2 port, and ISO 15552 mounting interface. The SAIJ features an upgraded piston seal for longer life.
The external stop screw provides a 10mm adjust window, allowing you to shorten the 20mm extend stroke down to 10mm on-site. The stop sets end position and is not a load lock.
