This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X280-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X280-100S 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 SIJ80X280-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X280-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 280mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X280-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X280-100S
The AirTAC SIJ80X280-100S is a double-acting, single-rod ISO 15552 adjustable-stroke cylinder. This discontinued unit features a 280mm nominal extend stroke that an external stop screw can shorten on-site by up to 100mm, yielding a usable 180-280mm window. The 80mm bore pairs with a G3/8 port, M20x1.5 rod thread, and 36mm adjustable cushions, delivering 2513N push and 2268N pull at 0.5 MPa, peaking at 4523N push at 0.9 MPa. The exact drop-in replacement is the SAIJ80X280-100S, matching the interface, bore, force, and port.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, the 2513N push at 0.5 MPa yields a safe working load of roughly 1508N (60%), or a 128kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Remember the stop screw sets the end position but is not a load lock; use SAIL or BSAI variants for air-loss holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X280-100S 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 SAIJ80X280-100S 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 SIJ80X280-100S Is Used
Variable-Length Clamping Press
Adjusts the extend stroke on-site to clamp parts of varying heights without re-engineering the entire fixture, utilizing the 100mm trim window for precise end-position tuning.
Adjustable Transfer Diverter
Tunes the extension length on a sorting line to accommodate different package widths, using the external stop screw to set the exact push distance for each product run.
Multi-Depth Insertion Tool
Sets variable insertion depths for components loaded into different cavity depths, relying on the 80mm bore's 2513N push at 0.5 MPa to seat parts reliably.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X280-100S with the SAIJ80X280-100S
To replace the discontinued SIJ80X280-100S, order the drop-in SAIJ80X280-100S, retaining the identical ISO 15552 mounting interface, 280mm stroke, and 100mm adjust window. When sizing both ways, the neighboring 63mm bore yields 1559N push at 0.5 MPa, while the 100mm bore yields 3927N. Select the 100mm adjust window if your process requires trimming the extend stroke anywhere from 180 to 280mm on-site. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. For strokes of 300mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X280-100S
- ✓ 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 SIJ80X280-100S FAQ
Yes, the SIJ80X280-100S is discontinued. The exact drop-in replacement is the SAIJ80X280-100S. It shares the identical ISO 15552 interface, 80mm bore, 280mm stroke, 100mm adjust window, G3/8 port, and mounting options, while upgrading the piston seal to two Y-shaped one-way elements for longer life.
The 80mm bore provides 2513N push and 2268N pull at 0.5 MPa, 3518N push at 0.7 MPa, and 4523N push at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The nominal 280mm extend stroke can be shortened on-site by up to 100mm via an external stop screw, yielding a usable 180-280mm stroke window. The stop sets end position but does not lock the load.
