This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X100-40, 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 SIJ80X100-40
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X100-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40
The AirTAC SIJ80X100-40 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. It features an 80mm bore, a 100mm nominal extend stroke, and an external stop screw that lets you trim the extend stroke by up to 40mm on-site, yielding a usable 60-100mm window. The stop sets the end position but is not a load lock. This SKU has no -S magnet and cannot take a sensor.
The direct replacement is the SAIJ80X100-40, preserving the ISO 15552 mounting interface, 25mm rod, G3/8 port, and force. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. For held loads, use SAIL/BSAI or an external rod lock, as air cushions only decelerate.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40 Is Used
Variable Depth Drilling Jig
Trim the extend stroke by up to 40mm on-site to change drill depth without swapping cylinders.
Adjustable Package Diverter
Tune the 100mm extend stroke to handle varying box widths on a packaging line.
Variable Height Pallet Stop
Field-adjust the end position to act as a physical stop for different pallet profiles.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-40 with the SAIJ80X100-40
To replace this discontinued SIJ80X100-40, order the direct replacement SAIJ80X100-40, keeping the 40mm adjust window (60-100mm usable extend) and G3/8 port. Reuse FA, LB, or TC mounts via the ISO 15552 interface. This non-magnetic SKU cannot take a switch; add -S for legacy CS1-B/DS1-B sensing. For stroke >=300mm, verify side-load guidance. Remember: double-acting double-rod only; the stop screw sets position, it does not lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
