This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X130-75S, 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 SIJ80X130-75S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X130-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-75S
The AirTAC SIJ80X130-75S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 55-130 mm window from the 130 mm nominal maximum.
The direct replacement is the SAIJ80X130-75S, matching the interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop sets end position but is not a load lock; for held loads use SAIL or BSAI.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-75S Is Used
Variable Depth Forming Press
Uses the 75 mm adjust window to tune the 130 mm extend stroke on-site for different material thicknesses without swapping the cylinder.
Multi-Height Pallet Stopper
Sets precise end positions for different pallet stack heights, using the G3/8 port and ISO 15552 mounts for rigid framing.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-75S with the SAIJ80X130-75S
To replace the discontinued SIJ80X130-75S, order the direct replacement SAIJ80X130-75S. Choose the 75 mm adjust window when you need to trim the 130 mm extend stroke down to a 55 mm minimum on-site; this avoids machining a custom fixed-rod length. Mounting interfaces (FA, LB, TC) reuse directly. The -S suffix includes a piston magnet for CS1-B/DS1-B switches. For stroke lengths >=300 mm, verify side-load guide tolerance. The stop screw sets end position only; it is not a lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X130-75S
- ✓ 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 SIJ80X130-75S FAQ
Yes, the SIJ80X130-75S is discontinued. The direct replacement is the SAIJ80X130-75S, which matches the ISO 15552 interface, 80 mm bore, 130 mm stroke, 75 mm adjust window, G3/8 port, and mounting. The SAIJ uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 75 mm adjust window, allowing you to shorten the 130 mm nominal extend stroke down to 55 mm on-site. The stop sets end position only and is not a load lock.
