This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X60-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X60-50S 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 SIJ80X60-50S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X60-50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X60-50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X60-50S
The AirTAC SIJ80X60-50S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 10 to 60 mm window from the 60 mm nominal maximum. The stop sets the end position but is not a load lock. This 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa.
The exact drop-in replacement is the SAIJ80X60-50S, matching the ISO 15552 interface, bore, force, and mountings. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, the safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), yielding a 128 kg vertical lift with a 2:1 margin. Note that a plain cylinder drifts on air loss; use an external rod lock or SAIL variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X60-50S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X60-50S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X60-50S Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to set precise drilling depths for different material thicknesses without swapping cylinders.
Variable Length Diverter
Tunes the extend stroke by up to 50 mm to deflect varying package sizes on a conveyor line accurately.
Adjustable Pusher Stop
Trims the extend position in sorting stations to handle changing box dimensions dynamically.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X60-50S with the SAIJ80X60-50S
To replace the discontinued SIJ80X60-50S, order the drop-in SAIJ80X60-50S, keeping the 50 mm adjust window and -S magnet for CS1-B/DS1-B switches. Size both ways by checking neighbor bores: the 63 mm gives 1559 N push, while the 100 mm gives 3927 N push at 0.5 MPa. Reuse FA, LB, or TC mounts via the ISO 15552 interface. The external stop screw shortens extend stroke by up to 50 mm on-site, but it is not a lock. For stroke lengths of 300 mm or more, verify side-load guidance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X60-50S
- ✓ 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 SIJ80X60-50S FAQ
Yes, the SIJ80X60-50S is discontinued. The exact drop-in replacement is the SAIJ80X60-50S, offering the same ISO 15552 interface, 80 mm bore, 60 mm stroke, 50 mm adjust window, G3/8 port, and mounting options. The SAIJ features an upgraded two Y-shaped one-way piston seal.
It delivers 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 max of 513 kgf at 1.0 MPa. The external stop screw provides a 50 mm adjust window, shortening the 60 mm nominal extend stroke down to 10 mm. The stop sets end position and is not a load lock.
