This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X500-30, 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 SIJ80X500-30
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X500-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30
The AirTAC SIJ80X500-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 470-500 mm window from the 500 mm nominal maximum.
This SKU is end-of-life; the direct replacement is the SAIJ80X500-30, which retains the ISO 15552 mounting interface, bore, and force. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position but is not a load lock.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30 Is Used
Press Tonnage Calibration
Needs field stroke tuning to set precise 470-500 mm extend endpoints during press tooling setup, using the external stop screw to dial in the exact contact depth without re-mounting the actuator.
Adjustable Stop Positioning
Demands an adjustable end-position stop to tune the extend stroke within the 470-500 mm window, allowing operators to reconfigure pallet stacking heights quickly without changing out the entire cylinder assembly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30 with the SAIJ80X500-30
To replace the discontinued SIJ80X500-30, order the direct replacement SAIJ80X500-30, ensuring you keep the -30 adjust window to maintain your 470-500 mm extend trim capability. Mounting reuse is guaranteed via the ISO 15552 interface using FA, LB, or TC brackets. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch for position sensing. Finally, at 500 mm stroke, account for side-load and rod-bending forces by incorporating external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X500-30
- ✓ 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 SIJ80X500-30 FAQ
Yes, the AirTAC SIJ80X500-30 is discontinued. The direct replacement is the SAIJ80X500-30.
The external stop screw provides a 30 mm adjust window, meaning the usable extend stroke is 470-500 mm. The stop sets the end position but is not a load lock; for load holding on air loss, use an external rod lock or SAIL variant.
