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

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300-S
The AirTAC MALD40X300-S is a discontinued double-acting, double-rod pneumatic cylinder. A rod exits both ends, delivering equal push and pull force of 528 N each way at 0.5 MPa (739 N at 0.7 MPa, max 108 kgf). The direct drop-in replacement is the MBLD40X300-S, matching the 40 mm bore, 300 mm stroke, G1/4 port, and mounting.
This -S variant includes a magnet for legacy CS1-M / DS1-M reed switches; the MBLD upgrade shifts to CMSG / DMSG / EMSG solid-state sensors. Unlike the threaded covers on this MALD, the MBLD uses a riveted rolling-packed body. Twin Ø16 mm hard-chrome rods resist torsion and double the bearing load, while the fixed rubber bumper absorbs end impacts without acting as a load lock.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD40X300-S |
| 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-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 MBLD40X300-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300-S

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-S Is Used
PCB Edge-Depaneling Router
Uses the 528 N equal both ways to hold and separate boards on the 300 mm stroke, while twin rods prevent torsional drift during the cutting pass.
Textile Beam Loom Feed
Drives a rear cam on the opposing rod to time the take-up tensioner, relying on the 40 mm bore's 739 N at 0.7 MPa for consistent pull force.
Bottle Capper Sync Slide
Slides a capping head over a 300 mm distance, using the fixed rubber bumper to soften the cap seating impact without requiring adjustable cushioning.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300-S with MBLD40X300-S
To replace the MALD40X300-S, specify the MBLD40X300-S to retain the 40 mm bore, 300 mm stroke, M12x1.25 rod-end, G1/4 port, and FA/LB mounting. Note that double-rod cylinders have no back cover or SDB option; mount strictly on the body or foot/flange. The -S magnet requires upgrading your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG. Size using the equal 528 N force; if you need less, step down to the 32 mm bore (346 N at 0.5 MPa). As the largest standard bore, there is no larger size up. For a 300 mm stroke, ensure external guide rails to prevent rod sag and side-load binding.
Upgrade checklist
- ✓ Order the MBLD40X300-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 MBLD40X300-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD40X300-S FAQ
Yes, the MALD40X300-S is discontinued. The exact drop-in replacement is the MBLD40X300-S, which matches the 40 mm bore, 300 mm stroke, G1/4 port, and FA/LB mounting. The MBLD upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
The push and pull forces are equal because both rod ends see the same annulus area. The ratings are 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa. The cylinder uses a fixed rubber bumper, not an adjustable cushion, and cannot hold a load on air loss.
