This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X175-100S, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X175-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100S
The AirTAC SIJ80X175-100S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the direct replacement SAIJ80X175-100S. It features an 80mm bore, G3/8 port, and a 175mm nominal stroke that you can trim by up to 100mm on-site via an external stop screw, yielding a usable extend range of 75-175mm. This stop sets the end position but is not a load lock.
The SAIJ replacement adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder drifts on air loss; for held loads use an external rod lock or the SAIL/BSAI lock variants.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100S Is Used
Variable Depth Forming
A press operation requiring field stroke tuning to alter the extend stroke by up to 100mm, adjusting the forming depth for different material thicknesses without swapping the entire cylinder.
Adjustable Transfer Pusher
A packaging line where the extend stroke must be trimmed on-site to push varying box sizes, using the 75-175mm usable range to accommodate different carton dimensions dynamically.
Variable Height Diverter
A sortation system needing field stroke tuning to deflect items of varying heights, using the external stop screw to set precise end positions for each product run.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100S with the SAIJ80X175-100S
To replace the discontinued SIJ80X175-100S, order the direct replacement SAIJ80X175-100S, matching the 80mm bore, 175mm stroke, and 100mm adjust window. The 100mm adjust window allows you to trim the extend stroke down to 75mm on-site without adding external stops. Reuse existing FA, LB, or TC ISO 15552 mounts. The -S suffix confirms the piston magnet is present for legacy CS1-B/DS1-B switches. For stroke lengths of 300mm or more, verify side-load limits to prevent excessive guide wear. Remember the stop screw sets end position and does not lock the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X175-100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100S FAQ
Yes, the SIJ80X175-100S is discontinued. The direct replacement is the SAIJ80X175-100S. It shares the same ISO 15552 interface, 80mm bore, 175mm stroke, 100mm adjust window, G3/8 port, and mounting options, but adds an upgraded piston seal.
The external stop screw provides a 100mm adjust window, allowing you to trim the extend stroke from the 175mm maximum down to 75mm on-site.
