This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD25X450, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 direct 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 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 direct 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.
