This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X150-30S, 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 SIJ80X150-30S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X150-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30S
The AirTAC SIJ80X150-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 150 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 120-150 mm window.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note the stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 120-150 mm extend position for seating bearings without machining hard stops.
Variable Transfer Diverter
Adjusts the extend stroke on-site to accommodate changing package widths on a sorting line.
Adjustable Pallet Stop
Fine-tunes the stopping distance for mixed pallet depths prior to the final locking sequence.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30S with the SAIJ80X150-30S
To replace the discontinued SIJ80X150-30S, order the direct replacement SAIJ80X150-30S, keeping the 150 mm nominal stroke and 30 mm adjust window (120-150 mm usable extend). Mounting interchange reuses basic, FA, LB, and TC ISO 15552 interfaces. The -S magnet supports legacy CS1-B/DS1-B sensors (current AirTAC switches on SAIJ). For strokes >=300 mm, verify guide alignment to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X150-30S
- ✓ 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 SIJ80X150-30S FAQ
Yes, the SIJ80X150-30S is discontinued. The direct replacement is the SAIJ80X150-30S.
The external stop screw provides a 30 mm adjust window, making the usable extend stroke 120-150 mm. The stop sets end position only; it is not a load lock.
