This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X350-S-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X350-S-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 MALD40X350-S-LB
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-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 MBLD40X350-S-LB, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-LB
The AirTAC MALD40X350-S-LB is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal 528 N force both ways at 0.5 MPa. The exact drop-in replacement is the MBLD40X350-S-LB, matching the 40mm bore, 350mm stroke, G1/4 port, and LB foot mount.
This unit features a fixed rubber bumper and threaded covers, while the MBLD upgrade uses a riveted rolling-packed body. The -S magnet on this MALD works with CS1-M / DS1-M switches; the MBLD replacement requires CMSG / DMSG / EMSG sensors. Twin rods resist rotation and double the bearing load for guided sliding.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-LB Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-LB |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X350-S-LB |
| 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-S-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 MBLD40X350-S-LB matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-LB
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×350 | 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 MALD40X350-S-LB Is Used
PCB Router Spindle
Twin rods resist spindle torque during PCB routing, keeping the 528 N cutting path true without rod twist.
Glass Edge Grinder
Dual rods guide the grinding head along 350mm of travel, applying equal 739 N force at 0.7 MPa on both push and pull strokes.
Pallet Transfer Gate
The rear rod acts as a mechanical flag for CS1-M sensors, confirming the gate position while the front rod shifts the pallet.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-LB with MBLD40X350-S-LB
Replace this MALD40X350-S-LB directly with the MBLD40X350-S-LB. Confirm the 40mm bore, 350mm stroke, G1/4 port, PT thread, and LB foot mounting (no back cover or SDB used). The -S magnet changes sensor families from CS1-M / DS1-M to CMSG / DMSG / EMSG. Size using the equal 528 N force at 0.5 MPa. To step down, the 32mm bore provides 346 N. To step up, 40mm is the largest available, so verify your load limits. At 350mm stroke, support the rod to prevent sagging and side-load wear on the bearings.
Upgrade checklist
- ✓ Order the MBLD40X350-S-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 MBLD40X350-S-LB instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X350-S-LB FAQ
Yes, the MALD40X350-S-LB is discontinued. The exact drop-in replacement is the MBLD40X350-S-LB, matching the 40mm bore, 350mm stroke, G1/4 port, and LB mount. You must switch from CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches for the -S magnet.
Because a rod exits both ends, both sides have the same annulus area. Push and pull forces are equal: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
