This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-40S in place of this model. 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 SIJ80X600-40S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X600-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40S
The AirTAC SIJ80X600-40S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 600 mm nominal stroke and a 40 mm on-site extend-trim window. An external stop screw lets you shorten the extend stroke down to 560 mm without changing mounts. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa (3518 N push at 0.7 MPa), uses a G3/8 port, and includes a 36 mm adjustable air cushion at each end. The exact drop-in replacement is the SAIJ80X600-40S, which shares the same interface, force, and porting.
The SAIJ upgrade uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push force), yielding a 128 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40S Is Used
Variable-Depth Forming Press
Trimming the extend stroke by up to 40 mm on-site allows operators to change material forming depths without swapping out the entire 600 mm cylinder.
Adjustable Length Diverter
Field-tuning the extend end position accommodates varying package sizes on a packaging line, ensuring precise 560 to 600 mm diversion strokes.
Variable-Height Pallet Stop
An external stop screw shortens the extend stroke on-site to handle mixed pallet heights, providing exact end-position tuning without custom spacers.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40S with the SAIJ80X600-40S
To replace the discontinued SIJ80X600-40S, order the drop-in SAIJ80X600-40S, keeping the same 80 mm bore, 600 mm stroke, 40 mm adjust window, and G3/8 port. For sizing both ways: the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push at 0.5 MPa. Choose the 40 mm adjust window if your extend stroke needs field tuning between 560 and 600 mm. Mounting options include Basic, FA, LB, and TC using the ISO 15552 interface. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B switches. Because the 600 mm stroke exceeds 300 mm, verify side-load limits, rod-bending forces, and use external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-40S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-40S FAQ
Yes, the SIJ80X600-40S is discontinued. The exact drop-in replacement is the SAIJ80X600-40S. It shares the same ISO 15552 interface, 80 mm bore, 600 mm stroke, 40 mm adjust window, G3/8 port, and mounting options, while adding an upgraded piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 40 mm adjust window, allowing the 600 mm extend stroke to be shortened to 560 mm on-site. The stop sets end position and is not a load lock.
