This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X600-40S, 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 SIJ100X600-40S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X600-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X600-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-40S
The AirTAC SIJ100X600-40S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw trims the extend stroke by up to 40 mm on-site, yielding a usable 560-600 mm window from the 600 mm nominal maximum. The 100 mm bore features a 25 mm rod, M20x1.5 thread, G1/2 port, and 36 mm adjustable cushions. The direct replacement is the SAIJ100X600-40S, sharing the same interface, bore, stroke, and force.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. This -S model includes a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-40S Is Used
Press Fit Tuning
Allows operators to trim the 600 mm extend stroke by up to 40 mm on-site to dial in exact press-fit depths for varying bearing housings without changing the cylinder.
Variable Length Diverter
A diverter arm that needs to reach different conveyor lane widths can use the external stop screw to shorten the extend position precisely for each product format change.
Adjustable Pallet Stop
End-of-line pallet stops require field stroke tuning to accommodate varying pallet overhang depths, using the 40 mm window to set the final stopping point accurately.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-40S with the SAIJ100X600-40S
To replace the discontinued SIJ100X600-40S, order the direct replacement SAIJ100X600-40S, which preserves the ISO 15552 mounting interface, G1/2 port, and 40 mm adjust window. Select the 40 mm adjust window if your extend stroke requires field tuning between 560 and 600 mm. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a built-in magnet for position sensing. Because the stroke is 600 mm, ensure external guides support side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X600-40S
- ✓ 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 SIJ100X600-40S FAQ
Yes, the SIJ100X600-40S is discontinued. The direct replacement is the SAIJ100X600-40S. It shares the same ISO 15552 interface, 100 mm bore, 600 mm stroke, 40 mm adjust window, G1/2 port, and mounting options, while adding an upgraded piston seal.
The external stop screw provides a 40 mm adjust window, allowing the extend stroke to be shortened from the 600 mm nominal maximum down to 560 mm. The stop sets end position and is not a load lock.
