This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X220-100S, 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 SIJ80X220-100S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X220-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 220mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X220-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X220-100S
The AirTAC SIJ80X220-100S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, discontinued and replaced by the SAIJ80X220-100S. Its external stop screw trims the extend stroke by up to 100 mm on-site, giving a usable 120-220 mm window from the 220 mm maximum. The 80 mm bore features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a G3/8 port.
The SAIJ direct keeps the ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. 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 SIJ80X220-100S Is Used
Variable Depth Forming
Tunes the extend stroke on-site to press parts of varying heights without swapping the entire cylinder.
Adjustable Diverter Arms
Allows operators to alter the divert stroke length for different package sizes directly at the conveyor lane.
Multi-Position Stacking
Provides adjustable end-position stops for stacking varied pallet loads without reconfiguring fixed hardware.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X220-100S with the SAIJ80X220-100S
Replace the discontinued SIJ80X220-100S directly with the SAIJ80X220-100S, reusing your existing FA, LB, or TC mounts. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches. For strokes over 300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X220-100S
- ✓ 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 SIJ80X220-100S FAQ
Yes, the SIJ80X220-100S is discontinued. The direct replacement is the SAIJ80X220-100S, sharing the same ISO 15552 interface, 80 mm bore, 220 mm stroke, 100 mm adjust window, G3/8 port, and mounting options.
The external stop screw provides a 100 mm trim window, allowing an extend stroke of 120-220 mm. The stop sets position but does not lock loads.
