This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X220-100S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X220-100S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X220-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 220mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X220-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X220-100S
The AirTAC SIJ100X220-100S is a discontinued double-acting double-rod adjustable-stroke ISO 15552 cylinder with a 100 mm bore and a 220 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 120-220 mm extension window. The direct replacement is the SAIJ100X220-100S, sharing the same ISO 15552 interface, force, and mounting.
The SAIJ upgrade incorporates an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets the end position but is not a load lock; the cylinder will drift on air loss. For held loads, use an external rod lock or the SAIL/BSAI lock variants. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X220-100S Is Used
Variable Depth Forming Press
Allows operators to dial in the exact 120-220 mm extend position on-site for punching or forming materials of varying thicknesses without changing the cylinder.
Adjustable Transfer Pusher
Tunes the extend stroke by up to 100 mm to accommodate different package sizes on a packaging line, ensuring precise placement at downstream stations.
Custom Height Pallet Stops
Provides a field-adjustable hard stop for pallets of varying heights, allowing quick changes to the end-of-stroke position without re-mounting hardware.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X220-100S with the SAIJ100X220-100S
To replace the discontinued SIJ100X220-100S, order the direct replacement SAIJ100X220-100S, which preserves the 220 mm stroke, 100 mm adjust window, G1/2 port, and FA/LB/TC mountings. The 100 mm adjust window is ideal if your extend position requires significant field tuning. The -S suffix indicates a built-in magnet for position sensing. For this 220 mm stroke, side-load is minimal, but for any stroke >=300 mm, ensure guide rails support the load to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X220-100S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X220-100S FAQ
Yes, the SIJ100X220-100S is discontinued. The direct replacement is the SAIJ100X220-100S. It shares the same ISO 15552 interface, 100 mm bore, 220 mm nominal stroke, 100 mm adjust window, G1/2 port, and mounting options, while adding an upgraded piston seal.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from 220 mm down to 120 mm on-site. The stop sets end position and is not a load lock.
