This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X210-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X210-100S 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 SIJ80X210-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X210-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 210mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X210-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X210-100S
The AirTAC SIJ80X210-100S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 210 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 110-210 mm window. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable air cushions. It delivers 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 SAIJ80X210-100S, sharing the same interface, force, and adjust window.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. A computed buyer insight from the 0.5 MPa data shows a safe working load around 1508 N, or a 128 kg 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 end position; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X210-100S 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 SAIJ80X210-100S 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 SIJ80X210-100S Is Used
Variable Pitch Pressing
Dial in exact 110 to 210 mm extend endpoints on-site to press fittings of varying heights without swapping the entire cylinder body.
Adjustable Diverter Arm
Trim the extend stroke by up to 100 mm to reposition a sorting gate precisely for different package widths on a packaging line.
Tiered Pallet Stops
Field-tune the 210 mm maximum stroke down to 110 mm to accommodate varying pallet load depths without adding mechanical spacers.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X210-100S with the SAIJ80X210-100S
To replace the discontinued SIJ80X210-100S, order the exact drop-in SAIJ80X210-100S. To size both ways: the 63 mm bore neighbor yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Select the 100 mm adjust window if you need the full 110-210 mm trim range. Reuse your FA, LB, or TC ISO 15552 mounts directly. The -S magnet supports legacy CS1-B/DS1-B sensors. For strokes at or over 300 mm, verify side-load guide tolerances. The external stop sets end position but does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X210-100S
- ✓ 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 SIJ80X210-100S FAQ
Yes, the SIJ80X210-100S is discontinued. The exact drop-in replacement is the SAIJ80X210-100S. It shares the identical ISO 15552 interface, 80 mm bore, 210 mm stroke, 100 mm adjust window, G3/8 port, and mounting options, while adding an upgraded Y-shaped piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa. The external stop screw window is 100 mm, allowing you to trim the extend stroke from the 210 mm maximum down to 110 mm on-site. The stop sets end position only; it is not a load lock.
