This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD32X450S, 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 MALD32X450-S
The AirTAC MALD Aluminum Alloy Mini Cylinder MALD32X450-S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø32mm bore, so push and pull force are equal. This model is discontinued — the direct replacement is the MBLD32X450-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD32X450-S
The AirTAC MALD32X450-S is a discontinued double-acting, double-rod mini cylinder. Because a rod exits both ends, the annulus area is identical on both sides, yielding equal push and pull force of 346 N each way at 0.5 MPa. The direct replacement is the MBLD32X450-S, matching the 32 mm bore, 450 mm stroke, G1/8 port, and mounting.
This -S variant includes a magnet for position sensing, originally using CS1-M or DS1-M switches. The MBLD upgrade uses CMSG / DMSG / EMSG sensors and improves durability with a riveted rolling-packed body, replacing the MALD's threaded covers. Both designs rely on a fixed rubber bumper for end-of-stroke impact absorption rather than an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD32X450-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD32X450-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD32X450-S |
| Bore size | Ø32 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 500 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD32X450-S carries the same ratings.
Output Force — Equal Both Ways (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD32X450-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD32X450-S Is Used
PCB Conveyor Diverters
Drives diverter arms on a PCB conveyor line, using the 346 N equal force both ways to push and pull panels smoothly without rotational drift.
Textile Slitting Knives
Positions slitting knives across a 450 mm fabric web, relying on the twin rods to resist torsional stress during high-speed cutting.
Dual-End Pneumatic Escapements
Operates a parts escapement where the rear rod simultaneously triggers a mechanical cam, keeping the 450 mm stroke perfectly synchronized.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD32X450-S with MBLD32X450-S
To replace the MALD32X450-S, specify the MBLD32X450-S to retain the 32 mm bore, 450 mm stroke, G1/8 port, M10x1.25 rod-end thread, and FA or LB mounting. There is no back-cover or SDB option on this double-rod body. You must also upgrade your sensing from CS1-M/DS1-M to CMSG/DMSG/EMSG switches. Size your load on the equal 346 N force at 0.5 MPa; if you need less force, step down to the 25 mm bore (206 N at 0.5 MPa), or step up to the 40 mm bore (528 N at 0.5 MPa) for more thrust. At 450 mm stroke, ensure your guide rails support the load to prevent rod bending and side-load damage.
Upgrade checklist
- ✓ Order the MBLD32X450-S (same bore/stroke/force)
- ✓ Force equal both ways (346 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 MBLD32X450-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD32X450-S FAQ
Yes, the MALD32X450-S is discontinued. The direct replacement is the MBLD32X450-S, which matches the 32 mm bore, 450 mm stroke, G1/8 port, and mounting. You will need to update your position sensors from the older CS1-M/DS1-M to the newer CMSG/DMSG/EMSG family.
The MALD32X450-S is a double-acting double-rod cylinder with equal force both ways: 346 N push and 346 N pull at 0.5 MPa, 484 N at 0.7 MPa, and a maximum of 70 kgf at 1.0 MPa. It has a 32 mm bore, 12 mm rods, M10x1.25 rod-end threads, a G1/8 port, and uses a fixed rubber bumper, not an adjustable cushion.
