This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X100-75S, 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 SIJ80X100-75S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-75S 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 SAIJ80X100-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-75S
The AirTAC SIJ80X100-75S 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 75 mm on-site, yielding a usable 25-100 mm extension from the 100 mm nominal maximum. It features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a fixed G3/8 port. The direct replacement is the SAIJ80X100-75S.
The SAIJ successor retains the ISO 15552 mounting interface, bore, stroke, adjust window, and force, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock, and a plain cylinder drifts on air loss.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-75S Is Used
Variable Stroke Pressing
Allows operators to dial in the exact extension distance for pressing bearings or pins where material thickness varies, using the 75 mm trim window to prevent over-travel.
Adjustable Diverters
Enables on-site tuning of the diverting arm reach on a packaging line, letting maintenance shorten the extend stroke by up to 75 mm without swapping the cylinder.
Variable Depth Stops
Provides a field-adjustable physical end-stop for pallet positioning, accommodating different pallet sizes by trimming the 100 mm nominal stroke down to 25 mm.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-75S with the SAIJ80X100-75S
To replace the discontinued SIJ80X100-75S, order the direct replacement SAIJ80X100-75S, which matches the ISO 15552 interface, 100 mm stroke, 75 mm adjust window, G3/8 port, and 25 mm rod. Choose the 75 mm adjust window if your application requires field tuning of the extend stroke between 25 and 100 mm. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a built-in piston magnet compatible with legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-75S
- ✓ 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 SIJ80X100-75S FAQ
Yes, the SIJ80X100-75S is discontinued. The direct replacement is the SAIJ80X100-75S. It shares the same ISO 15552 interface, 80 mm bore, 100 mm nominal stroke, 75 mm adjust window, G3/8 port, and 25 mm rod, but features an upgraded piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extension range of 25-100 mm. The stop sets end position only and is not a load lock.
