This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X100-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X100-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 MALD20X100-LB
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB 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 drop-in replacement is the MBLD20X100-LB, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB
The AirTAC MALD20X100-LB is a discontinued double-acting, double-rod miniature cylinder. A rod exits both ends of the 20 mm bore, yielding exactly 132 N of force in both push and pull directions at 0.5 MPa. The direct drop-in replacement is the MBLD20X100-LB, matching the 100 mm stroke, G1/8 port, and LB foot mounting.
This SKU has no magnet and cannot accept a position sensor. It uses a fixed rubber bumper rather than an adjustable cushion. The original MALD features threaded covers and a heterogeneous grease-retaining seal, whereas the MBLD upgrade uses a riveted rolling-packed body. The twin carbon-steel rods are hard-chrome plated to resist wear and double the bearing area for guided sliding.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X100-LB |
| Bore size | Ø20 mm |
| Stroke | 100 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 MBLD20X100-LB 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 MBLD20X100-LB matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB Is Used
PCB Depaneling Saw
Drives a synchronized cutting blade carriage where the twin 8 mm rods prevent yaw. The 132 N equal force ensures clean cuts in both directions without rotational drift.
Pick-and-Place Transfer
Moves small electronic caps between belts. The rear rod acts as a stable mounting post for a secondary mechanical ejector, keeping the 100 mm stroke perfectly aligned.
Label Applicator Platen
Presses adhesive labels onto cartons. The fixed rubber bumper absorbs the end-of-stroke impact, while the LB foot mount secures the body firmly to the framing.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB with MBLD20X100-LB
To replace the MALD20X100-LB, specify the MBLD20X100-LB. Confirm the 20 mm bore, 100 mm stroke, G1/8 port, PT thread, and LB foot mount. Because this SKU lacks the -S magnet, it cannot support a sensor; the MBLD upgrade would require CMSG, DMSG, or EMSG switches if sensing is added later. Size using the equal-both-ways force of 132 N at 0.5 MPa.
If you need to step down, the smallest available bore is this 20 mm size. If you need to step up, the next larger bore is 25 mm, which provides 206 N at 0.5 MPa. At a 100 mm stroke on a mini bore, ensure your load is guided to prevent rod side-loading and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD20X100-LB (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 MBLD20X100-LB instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X100-LB FAQ
Yes, the MALD20X100-LB is discontinued. The exact drop-in replacement is the MBLD20X100-LB, which matches the 20 mm bore, 100 mm stroke, G1/8 port, and LB foot mount. The MBLD upgrades the construction with a riveted rolling-packed body instead of threaded covers.
Because a rod exits both ends, the piston sees the same annulus area on both sides, making push and pull force identical. The ratings are 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. Note that this specific SKU lacks a magnet, so it cannot accept CS1-M or DS1-M position sensors.
