This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X450 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X450 in place of this model. The MBLD replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450 is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø25mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD25X450, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450
The AirTAC MALD25X450 is a discontinued double-acting, double-rod pneumatic cylinder. Because rods exit both ends, the annulus area is identical on both sides, yielding equal push and pull force of 206 N at 0.5 MPa. The direct drop-in replacement is the MBLD25X450, matching the 25 mm bore, 450 mm stroke, G1/8 port, and mounting.
This 450 mm stroke exceeds the 300 mm standard maximum, making it a non-standard, made-to-order unit that requires careful side-load management to prevent rod binding. This SKU lacks a magnet and cannot support position sensors. The original MALD uses threaded covers and fixed rubber bumpers; upgrading to the MBLD25X450 brings a riveted rolling-packed body while retaining the same equal-force ratings.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X450 |
| Bore size | Ø25 mm |
| Stroke | 450 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD25X450 carries the same ratings.
Output Force — Equal Both Ways (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | 289 N |
| Max (@1.0 MPa) | 42 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD25X450 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450 Is Used
PCB Edge Conveyor Transfer
Drives a dual-belt conveyor edge guide in a PCB assembly line. The twin rods prevent chassis twist over the 450 mm travel, while the 206 N equal force ensures consistent panel tracking without skewing.
Long-Stroke Pneumatic Slide
Moves a pick-and-place shuttle across a 450 mm span in a packaging machine. The rear rod acts as a stable mounting point for a secondary tool, keeping the payload balanced over the extended length.
Textile Yarn Guide Traverse
Oscillates a yarn guide bar on a winding machine. The fixed rubber bumper softens the rapid directional reversals at 450 mm, absorbing end-impact without requiring an adjustable cushion valve.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450 with MBLD25X450
To replace the MALD25X450, specify the MBLD25X450 directly. Confirm the G1/8 port, M10x1.25 rod-end thread, and FA or LB mounting (there is no back-cover or SDB option). Since this SKU lacks the -S magnet, it cannot take a sensor; if you need position sensing, order the MBLD25X450S which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
Size on the equal 206 N (0.5 MPa) force both ways. If you need less force, step down to the 20 mm bore providing 132 N each way. If you need more force, step up to the 32 mm bore delivering 346 N each way. At 450 mm, always guide the load externally to prevent excessive rod side-loading and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD25X450 (same bore/stroke/force)
- ✓ Force equal both ways (206 N at 0.5 MPa)
- ✓ Twin rods for anti-rotation / rear flag
- ✓ No back cover / SDB — plan a body or FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Protect both rod ends from side load on long strokes.
- check No back-cover / SDB on double-rod — use body / FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLD25X450 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X450 FAQ
Yes, the MALD25X450 is discontinued. The exact drop-in replacement is the MBLD25X450. It matches the 25 mm bore, 450 mm stroke, G1/8 port, and FA/LB mounting. The MBLD upgrades the body to a riveted rolling-packed design while keeping the same force ratings.
Because a rod exits both ends, the piston sees the same annulus area in both directions, making push and pull force equal. The exact figures are 206 N each way at 0.5 MPa, 289 N each way at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. This unit has no magnet, so it cannot take a position sensor.
