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

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175
The AirTAC MALD40X175 is a discontinued double-acting, double-rod mini cylinder delivering 528 N of equal force in both directions at 0.5 MPa. The exact drop-in replacement is the MBLD40X175, matching the 40 mm bore, 175 mm stroke, G1/4 port, and mounting footprint.
This 40 mm bore unit features a 16 mm hard-chrome carbon steel rod exiting both covers, doubling the bearing surface to resist side loads. Because this SKU lacks the -S magnet, it cannot accept position sensors. The original MALD uses threaded covers and fixed rubber bumpers, whereas the MBLD upgrade features a riveted rolling-packed body for enhanced structural integrity.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175 Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175 |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X175 |
| 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 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 matches these values.

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 Is Used
PCB Depaneling Saw
Drives a synchronized cutting blade on a printed circuit board router, using the 528 N equal force to maintain consistent blade pressure on both the advance and retract strokes.
Textile Loom Beater
Oscillates the reed mechanism in a weaving machine, where the twin 16 mm rods absorb high reversing side-loads and prevent torsional deflection during rapid cycling.
Pallet Transfer Gate
Actuates a diverter flap on a packaging conveyor, relying on the dual-rod geometry to hold the 175 mm extended flap rigid against impacting cartons without twisting.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175 with MBLD40X175
To replace the MALD40X175, specify the MBLD40X175 and confirm the G1/4 port, M12x1.25 rod-end thread, and FA or LB mounting (there is no back-cover or SDB option on this body). Size your application on the 528 N equal push/pull force at 0.5 MPa. If you need less force, step down to the 32 mm bore providing 346 N; if you need more, this 40 mm bore is the largest in the series at 528 N. At 175 mm stroke, mount this cylinder using FA or LB to minimize rod side-loading and prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLD40X175 (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 instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X175 FAQ
Yes, the MALD40X175 is discontinued. The exact drop-in replacement is the MBLD40X175, which matches the 40 mm bore, 175 mm stroke, G1/4 port, and 528 N equal force. The MBLD upgrades the construction to a riveted rolling-packed body.
This double-rod cylinder provides equal force both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept CS1-M or DS1-M position sensors; the MBLD replacement uses CMSG, DMSG, or EMSG switches.
