This model is discontinued
AirTAC has phased out the MALD series. You can still order this code here: we ship the direct replacement MBLD20X150S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALD20X150-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø20mm bore, so push and pull force are equal. This model is discontinued — the direct replacement is the MBLD20X150-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S
The AirTAC MALD20X150-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so the annulus area is identical on each side, yielding equal push and pull force of 132 N at 0.5 MPa. The direct replacement is the MBLD20X150-S, matching the 20 mm bore, 150 mm stroke, G1/8 port, and mounting.
This -S SKU includes a magnet for position sensing. The original MALD uses CS1-M or DS1-M reed switches, while the MBLD upgrade uses CMSG, DMSG, or EMSG solid-state sensors. The legacy MALD has threaded covers, whereas the MBLD features a riveted rolling-packed body. Both lack a back cover or SDB auto-switch bracket, so you mount directly via the body or an FA/LB bracket.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X150-S |
| Bore size | Ø20 mm |
| Stroke | 150 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 mm |
Double-rod types have no back-cover code and no SDB pivot; mount on the body, LB foot or FA flange. The MBLD20X150-S carries the same ratings.
Output Force — Equal Both Ways (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | 185 N |
| Max (@1.0 MPa) | 27 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD20X150-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S Is Used
PCB Depaneling Saw
Drives a synchronized cutting blade on a printed circuit board router, using the twin rods to prevent blade yaw while applying 132 N of equal push and pull force.
Label Applicator Arm
Pivots a tamp pad on a packaging line; the rear rod carries a cam to trigger a mechanical flag, verifying stroke position without relying solely on the CS1-M sensor.
Gripper Slide Sync
Actuates a synchronized dual-jaw gripper for small electronic component pickup, ensuring both jaws close simultaneously with equal 185 N force at 0.7 MPa.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S with MBLD20X150-S
To replace the MALD20X150-S, order the MBLD20X150-S. Confirm your 20 mm bore, 150 mm stroke, G1/8 port, M8x1.25 rod-end thread, and FA/LB mounting. The magnet code (-S) carries over, but you must upgrade from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. Size your loads on the equal both-ways force: 132 N at 0.5 MPa and 185 N at 0.7 MPa.
If you need to step down, the adjacent bore is not smaller for this double-rod family, so 20 mm is the minimum. Stepping up to the 32 mm bore yields 346 N at 0.5 MPa. At a 150 mm stroke, twin rods resist rotation well, but always verify the rod-to-side-load ratio to prevent bearing wear on long slides.
Upgrade checklist
- ✓ Order the MBLD20X150-S (same bore/stroke/force)
- ✓ Force equal both ways (132 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 MBLD20X150-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X150-S FAQ
Yes, the MALD20X150-S is discontinued. The direct replacement is the MBLD20X150-S, matching the 20 mm bore, 150 mm stroke, G1/8 port, and mounting. The MBLD uses a riveted rolling-packed body instead of threaded covers, and its magnet works with CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
Because it is a double-rod cylinder, push and pull forces are equal: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. It uses a fixed rubber bumper at end-of-stroke to soften impact; it is not an adjustable cushion and will not hold the load on air loss.
