This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X50-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X50-10S 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 SIJ80X50-10S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X50-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 50mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X50-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X50-10S
The AirTAC SIJ80X50-10S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder. A 50mm nominal extend stroke is trimmed on-site by up to 10mm via an external stop screw, yielding a 40-50mm usable window. The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, features a 25mm rod, M20x1.5 thread, and a G3/8 port. This SIJ model is discontinued; the exact drop-in replacement is the SAIJ80X50-10S, sharing the same interface, force, and mounting.
The SAIJ successor retains ISO 15552 mounting reuse and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Computed buyer insight: safe working load is roughly 1508N (60% of the 0.5MPa push), allowing a 128kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a lock; loads drift on air loss. For load holding, use SAIL/BSAI variants or an external rod lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X50-10S 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 SAIJ80X50-10S 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 SIJ80X50-10S Is Used
Press Fit Tuning
Dialing in a 40-50mm insertion stroke for bearing press fits, allowing on-site adjustment without swapping cylinders.
Diverter Gate Stroke
Adjusting a diverter gate endpoint by up to 10mm to accommodate varying package sizes on a packaging line.
Product Stop Positioning
Fine-tuning a pneumatic product stop on a roller conveyor to handle different pallet widths precisely.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X50-10S with the SAIJ80X50-10S
To replace the discontinued SIJ80X50-10S, order the drop-in SAIJ80X50-10S. To size both ways: the 63mm bore neighbor gives 1559N push @0.5MPa, while the 100mm bore gives 3927N push. Choose the 10mm adjust window if you need precise 40-50mm extend tuning. Mounting options include FA, LB, and TC brackets. The -S suffix indicates a piston magnet for CS1-B/DS1-B switches. For this 50mm stroke, side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X50-10S
- ✓ 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 SIJ80X50-10S FAQ
Yes, the SIJ80X50-10S is discontinued. The exact drop-in replacement is the SAIJ80X50-10S. It shares the same ISO 15552 interface, 80mm bore, 50mm stroke, 10mm adjust window, G3/8 port, and mounting options, while adding an upgraded piston seal.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa, with a theoretical max of 513kgf at 1.0MPa. The external stop screw allows trimming the extend stroke by up to 10mm on-site, giving a usable 40-50mm stroke. The stop sets end position and is not a load lock.
