This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X200-100S, 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 SIJ80X200-100S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X200-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100S
The AirTAC SIJ80X200-100S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 200 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 100-200 mm window. The 80 mm bore features a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions at each end. The direct replacement is the SAIJ80X200-100S, sharing the exact interface, force, and mounting.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure. Remember the stop screw sets end position only; it is not a load lock, so use SAIL or BSAI for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100S Is Used
Variable Depth Spot Facing
Machine operators trim the extend stroke by up to 100 mm on-site to hit precise facing depths on cast parts without swapping the entire cylinder body.
Adjustable Transfer Pusher
Diverter arms use the 100-200 mm usable window to tune the push distance for varying package widths directly on the conveyor line.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100S with the SAIJ80X200-100S
To replace the discontinued SIJ80X200-100S, order the direct replacement SAIJ80X200-100S, reusing your FA, LB, or TC mounts. The 100 mm adjust window is ideal for dialing in the exact extend position without machining. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches; the SAIJ uses current switches. For stroke lengths of 300 mm or more, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-100S
- ✓ 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 SIJ80X200-100S FAQ
Yes, the SIJ80X200-100S is discontinued. The direct replacement is the SAIJ80X200-100S. It shares the identical ISO 15552 interface, 80 mm bore, 200 mm stroke, 100 mm adjust window, G3/8 port, and mounting options, but adds an upgraded two Y-shaped one-way piston seal.
The external stop screw allows you to trim the extend stroke by up to 100 mm on-site, giving a usable 100-200 mm window from the 200 mm nominal stroke. The stop sets end position only and is not a load lock.
