This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X600-75S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X600-75S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X600-75S 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 SAIJ100X600-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-75S
The AirTAC SIJ100X600-75S is a discontinued double-acting double-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 525-600 mm window from the 600 mm nominal maximum. It features a 25 mm rod, M20x1.5 thread, G1/2 port, and 36 mm adjustable cushions. The direct replacement is the SAIJ100X600-75S, sharing the exact interface, force, and mounting.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The stop screw sets end position only; it is not a load lock. Because drift occurs on air loss, use an external rod lock or check valve for held loads. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-75S Is Used
Press Fit Tuning
Final insertion depth requires field stroke tuning. Trim the extend stroke by up to 75 mm on-site to set precise 525-600 mm press positions without machining spacers.
Variable Length Diverter
A diverting gate must handle changing package sizes. The external stop screw adjusts the extend end-point on-site, accommodating various product lengths on the line.
Adjustable Height Pallet Stop
Pallet stops need flexibility for varying stack heights. The 75 mm adjust window allows operators to tune the 600 mm extend stroke to the exact required stopping distance.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-75S with the SAIJ100X600-75S
To replace the discontinued SIJ100X600-75S, order the SAIJ100X600-75S direct: it matches the 100 mm bore, 600 mm stroke, 75 mm adjust window, G1/2 port, and ISO 15552 mounting. The 75 mm adjust window is ideal if your end position needs field tuning between 525 and 600 mm. Reuse FA, LB, or TC mounts. The -S suffix includes a piston magnet for legacy CS1-B/DS1-B switches. At 600 mm stroke, mind side-load and rod-bending; use external guides to prevent excessive deflection.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X600-75S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X600-75S FAQ
Yes, the SIJ100X600-75S is discontinued. The direct replacement is the SAIJ100X600-75S. It shares the same ISO 15552 interface, 100 mm bore, 600 mm stroke, 75 mm adjust window, G1/2 port, and mounting. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for longer life.
The theoretical max is 801 kgf at 1.0 MPa. The external stop screw offers a 75 mm adjust window, shortening the 600 mm nominal extend stroke to a minimum of 525 mm. The stop sets end position only and is not a load lock.
