This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD40X175-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD40X175-S 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 MALD40X175-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S 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 MBLD40X175-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S
The AirTAC MALD40X175-S is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends of the 40mm bore, yielding 528 N of equal force both ways at 0.5 MPa. The exact drop-in replacement is the MBLD40X175-S, matching the 175mm stroke, G1/4 port, and mounting.
This -S SKU includes a magnet for CS1-M / DS1-M switches; the MBLD40X175-S upgrade uses CMSG / DMSG / EMSG sensors. The MALD features threaded covers, while the MBLD uses a riveted rolling-packed body. Twin rods double the bearing load and resist rotation, letting the rear rod carry a cam or secondary tool. It uses a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X175-S |
| Bore size | Ø40 mm |
| Stroke | 175 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 MBLD40X175-S 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 MBLD40X175-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S
| MALD | Double-rod aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×175 | 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 MALD40X175-S Is Used
PCB Edge Deburring Station
Uses the 528 N equal force to clamp boards on both strokes, while twin rods resist twist during the deburring brush pass.
Textile Loom Beater
The rear rod carries a cam to time the weft insertion, matching the 175mm stroke without needing a separate actuator.
Packaging Lid Press
Applies 739 N at 0.7 MPa to seal cartons, with the double-rod symmetry keeping the press plate perfectly level.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S with MBLD40X175-S
To replace the MALD40X175-S, specify the MBLD40X175-S and confirm the 40mm bore, 175mm stroke, G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Change the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. Size on the 528 N equal push-pull force at 0.5 MPa. Stepping down, the 32mm bore yields 346 N; stepping up is not possible as 40mm is the largest MALD size. At 175mm stroke, ensure external guides support side loads to prevent binding.
Upgrade checklist
- ✓ Order the MBLD40X175-S (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 MBLD40X175-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175-S FAQ
Yes, the MALD40X175-S is discontinued. The exact drop-in replacement is the MBLD40X175-S, which matches the 40mm bore, 175mm stroke, 528 N force, G1/4 port, and FA/LB mounting. You must update your sensors: the MALD -S magnet works with CS1-M/DS1-M switches, while the MBLD uses CMSG/DMSG/EMSG switches.
The double-rod design provides equal force both ways: 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a maximum force of 108 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke impact, not an adjustable cushion or load-holding lock.
