This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X350 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X350 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 MALD40X350
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350 is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø40mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD40X350, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350
The AirTAC MALD40X350 is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, generating 528 N of equal force both ways at 0.5 MPa. The exact drop-in replacement is the MBLD40X350, matching the 350mm stroke, G1/4 port, and mounting footprint.
This SKU has no -S magnet and cannot accept a position sensor. The original MALD uses threaded covers and fixed rubber bumpers, while the MBLD upgrade features a riveted rolling-packed body. The twin 16mm carbon-steel chrome rods resist rotation and double the bearing load for guided sliding.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X350 |
| Bore size | Ø40 mm |
| Stroke | 350 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 MBLD40X350 carries the same ratings.
Output Force — Equal Both Ways (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |
| Max (@1.0 MPa) | 108 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD40X350 matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350 Is Used
PCB Router Spindle Slide
Drives a guided Z-axis slide for PCB depaneling routers. The twin rods provide anti-rotation stability over the 350mm travel, while the 528 N equal force ensures consistent plunge and retract cutting depths.
Textile Beam Indexer
Indexes a warp beam carriage in a weaving loom. The dual rods carry a rear cam flag to trip mechanical stoppers, leveraging the 739 N force at 0.7 MPa to shift heavy cloth rolls without rotational drift.
Bottle Capper Press
Applies torque caps on a bottling line using a fixed rear tooling bracket. The equal push-pull force handles capping and extraction identically, while the fixed rubber bumper softens the 350mm stroke end impact.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350 with MBLD40X350
Replace this MALD40X350 with the exact drop-in MBLD40X350. Confirm the 40mm bore, 350mm stroke, G1/4 port, M12x1.25 rod-end thread, and PT thread form. Since this SKU lacks an -S magnet, it cannot hold a sensor; the MBLD upgrade uses CMSG, DMSG, or EMSG switches if sensing is needed.
Size on the equal 528 N force (108 kgf max). To step down, the 32mm bore neighbor provides 346 N at 0.5 MPa. To step up beyond 40mm requires a different frame. At 350mm stroke, twin rods help, but always guide the load externally to prevent side-load bending on long strokes. Mount via FA flange or LB foot; there is no back cover or SDB option.
Upgrade checklist
- ✓ Order the MBLD40X350 (same bore/stroke/force)
- ✓ Force equal both ways (528 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 MBLD40X350 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350 FAQ
Yes, the MALD40X350 is discontinued. The exact drop-in replacement is the MBLD40X350, matching the 40mm bore, 350mm stroke, 528 N equal force, and G1/4 port. The MBLD upgrades the body to a riveted rolling-packed design.
Because a rod exits both ends, both sides see the same annulus area, making push and pull force identical. The figures are 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. This specific SKU has no -S magnet, so it cannot accept a position sensor.
