This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X800-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X800-75 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 SIJ80X800-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X800-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-75
The AirTAC SIJ80X800-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 800 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 725-800 mm end position. The stop sets the end position firmly but is not a load lock; the 36 mm adjustable air cushions only decelerate the piston near stroke ends. This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa.
The exact drop-in replacement is the SAIJ80X800-75, matching the bore, stroke, 513 kgf max force, and mounting interface. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet and cannot accept a sensor.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-75 Is Used
Variable-Length Pressing
Adjusting the 75 mm extend stop on-site allows a press to hit varying material thicknesses without reprogramming the PLC or changing the entire cylinder.
Adjustable Transfer Diverter
Tuning the extend end position lets a diverter gate accommodate different package widths on the fly, ensuring precise routing without mechanical spacers.
Variable-Depth Pallet Stops
Trimming the extend stroke by up to 75 mm enables a stopper to handle varying pallet footprints dynamically, securing loads accurately at the end of the line.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-75 with the SAIJ80X800-75
To replace the discontinued SIJ80X800-75, map directly to the SAIJ80X800-75 drop-in, retaining the ISO 15552 mounting dimensions and the G3/8 port. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N; this 80 mm bore provides 2513 N. Choose the 75 mm adjust window if your extend stroke needs field tuning between 725 and 800 mm. Reuse FA, LB, or TC mounts. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. Finally, at an 800 mm stroke, mind the side-load and rod-bending risks by using external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X800-75
- ✓ 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 SIJ80X800-75 FAQ
Yes, the SIJ80X800-75 is discontinued. The exact drop-in replacement is the SAIJ80X800-75, which shares the same ISO 15552 interface, 80 mm bore, 800 mm stroke, 75 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
This double-acting single-rod cylinder delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 75 mm adjust window, allowing the extend stroke to be shortened from 800 mm down to 725 mm on-site. The stop sets the end position but is not a load lock.
