This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X100-20, 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 SIJ80X100-20
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-20 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 SAIJ80X100-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-20
The AirTAC SIJ80X100-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 100mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 80-100mm extension window. This SKU lacks a magnet (-S), so it cannot accept a magnetic switch. The direct replacement is the SAIJ80X100-20, matching the interface, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a lock; without live air the piston drifts. For held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-20 Is Used
Press Fit Tuning
Allows operators to dial in the exact 80-100mm extend position on-site for inserting parts without machining hard stops.
Variable Diverter Gate
Adjusts the extend stroke by up to 20mm to deflect different package sizes accurately on a sorting line.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X100-20 with the SAIJ80X100-20
To replace the discontinued SIJ80X100-20, specify the direct replacement SAIJ80X100-20, keeping the 20mm adjust window, 100mm nominal stroke, G3/8 port, and FA/LB/TC mountings. Choose the 20mm adjust window if you need field stroke tuning between 80-100mm. Because this specific SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; confirm if you need sensing. For stroke lengths over 300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X100-20
- ✓ 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 SIJ80X100-20 FAQ
Yes, the SIJ80X100-20 is discontinued.
The external stop screw offers a 20mm trim window, allowing the extend stroke to be shortened from the 100mm maximum down to 80mm on-site.
