This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X300 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 MALD40X300
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300 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 MBLD40X300, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300
The AirTAC MALD40X300 double-acting, double-rod cylinder is discontinued; its exact drop-in replacement is the MBLD40X300. It delivers 528 N of equal force both ways at 0.5 MPa, utilizing a 40 mm bore, G1/4 port, and 300 mm stroke.
Because a rod exits both ends, the annulus area is identical on each side, making push and pull forces perfectly symmetrical. This MALD unit uses threaded covers and a fixed rubber bumper. As a non-magnet SKU, it cannot accept a position sensor. The MBLD upgrade improves durability with a riveted rolling-packed body.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X300 |
| Bore size | Ø40 mm |
| Stroke | 300 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 MBLD40X300 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 MBLD40X300 matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×300 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLD uses CMSG/DMSG/EMSG). |
Replacement: MALD → MBLD. No back-cover (CA/U/CM) and no SDB on double-rod. Mounting: LB / FA.
Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300 Is Used
Printed Circuit Board Drilling
Provides 528 N of equal push and pull force to drive a drill head over a 300 mm stroke, ensuring precise hole depth without rotational drift.
Injection Mold Ejection
Uses the twin-rod anti-rotation capability to push and pull a mold ejector plate symmetrically, preventing binding during the 300 mm travel.
Dual-Tool Slide Transfer
Mounts a pickup tool on the front rod and a cam flag on the rear rod, moving parts across a 300 mm machining station with matched force.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300 with MBLD40X300
Replace this MALD40X300 with the MBLD40X300, confirming the 40 mm bore, 300 mm stroke, G1/4 port, and PT thread form. Mounting is FA flange or LB foot only; there is no back-cover or SDB option. This non-magnet SKU cannot hold a sensor; upgrading to an -S MBLD requires CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Size strictly on the 528 N equal force. Stepping down, the 32 mm bore provides 346 N; stepping up is not possible as 40 mm is the largest MALD size. At 300 mm stroke, ensure external guides support the rod to prevent side-loading and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD40X300 (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 MBLD40X300 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300 FAQ
Yes, the MALD40X300 is discontinued. The exact drop-in replacement is the MBLD40X300, which matches the 40 mm bore, 300 mm stroke, 528 N equal force, and G1/4 port. The MBLD upgrades the body to a riveted rolling-packed design.
Force is equal because a rod exits both ends, making the annulus piston area identical for push and pull. The full force ratings are 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a maximum of 108 kgf at 1.0 MPa.
