This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X150-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X150-LB 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 MALD40X150-LB
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB 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 MBLD40X150-LB, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB
The AirTAC MALD40X150-LB is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, delivering equal force both ways at 528 N @0.5 MPa and 739 N @0.7 MPa. The direct drop-in replacement is the MBLD40X150-LB, matching the 150mm stroke, G1/4 port, and LB foot mounting.
This SKU has no -S magnet and cannot take a position sensor. The MALD uses threaded covers and a fixed rubber bumper, while the MBLD upgrade features a riveted rolling-packed body. Twin rods resist rotation, double the bearing load, and allow mounting a cam or tool on the rear rod.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X150-LB |
| Bore size | Ø40 mm |
| Stroke | 150 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 MBLD40X150-LB 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 MBLD40X150-LB matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×150 | Stroke length in mm. |

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 MALD40X150-LB Is Used
Servo-Drive Slitter Knife
Guides the slitting blade on a paper mill winder. The twin rods prevent blade yaw during 528 N cuts, while the rear rod mounts a tracking flag.
Glass Edge Seaming Jig
Drives the clamping pad on an automotive glass seamer. Equal push/pull force keeps the 40mm bore pad centered without drift.
Bottle Capper Turret
Actuates the capping head on a rotary bottling line. The LB foot mount stabilizes the 150mm stroke against high cyclic side-load.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB with MBLD40X150-LB
To replace the MALD40X150-LB with the MBLD40X150-LB, confirm the 40mm bore, 150mm stroke, PT G1/4 port, M12x1.25 rod thread, and LB foot mount. This SKU lacks a magnet (-S), so it cannot fit a sensor; if you need sensing, the MBLD-S uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Size your actuator on the equal 528 N force. Stepping down, the 32mm bore yields 346 N @0.5 MPa; stepping up is not possible as 40mm is the largest MALD bore. At 150mm stroke, ensure side-load alignment to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLD40X150-LB (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 MBLD40X150-LB instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X150-LB FAQ
Yes, the MALD40X150-LB is discontinued. The exact drop-in replacement is the MBLD40X150-LB, matching the 40mm bore, 150mm stroke, G1/4 port, and LB foot mount. The MBLD upgrades the body to a riveted rolling-packed design.
Force is equal because both sides of the piston see the same annulus area due to the double-rod design. The figures are: 528 N push and 528 N pull @0.5 MPa; 739 N push and 739 N pull @0.7 MPa; max 108 kgf @1.0 MPa. This SKU has no -S magnet, so it cannot take a sensor.
