This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X70-10, 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 SIJ80X70-10
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X70-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 70mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X70-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X70-10
The AirTAC SIJ80X70-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 60-70 mm forward travel out of the 70 mm nominal maximum. This SIJ model is discontinued; the direct replacement is the SAIJ80X70-10, matching the bore, force, adjust window, port, and mounting.
The SAIJ upgrade introduces an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. Because this SKU lacks a -S magnet, it cannot accept a magnetic switch. Note the stop screw sets end position only; it is not a load lock, and the cylinder will drift on air loss.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X70-10 Is Used
Press Fit Dialing
Light-duty press operations requiring exact end-position tuning, using the 10 mm adjust screw to dial in the 60-70 mm extend stroke for perfect component seating without re-plumbing.
Clamp Position Setup
Machining clamps needing precise 60-70 mm reach; the adjustable stop screw sets the exact clamp position on-site, while the G3/8 port delivers 2268 N pull force at 0.5 MPa.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X70-10 with the SAIJ80X70-10
To replace the discontinued SIJ80X70-10, order the direct replacement SAIJ80X70-10, which reuses the exact ISO 15552 mounting interface and dimensions. Choose the 10 mm adjust window when you need minor on-site extend tuning between 60 and 70 mm. Reuse existing FA, LB, or TC mounts. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; confirm external sensing needs. Since the 70 mm stroke is under 300 mm, side-load rod deflection is minimal. For load-holding without live air, the adjust screw is not a lock; specify an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X70-10
- ✓ 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 SIJ80X70-10 FAQ
Yes, the SIJ80X70-10 is discontinued. The direct replacement is the SAIJ80X70-10. It shares the identical ISO 15552 interface, 80 mm bore, 70 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The external stop screw provides a 10 mm adjust window, allowing you to trim the extend stroke from the 70 mm nominal maximum down to 60 mm on-site. The stop sets end position only and is not a load lock.
