This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X175-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X175-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 MALD20X175-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175-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 drop-in replacement is the MBLD20X175-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175-S
The AirTAC MALD20X175-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, giving equal push and pull force of 132 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD20X175-S, matching the 20 mm bore, 175 mm stroke, G1/8 port, and M8x1.25 rod thread.
This twin-rod design resists rotation and doubles the bearing load for guided slides. The -S magnet enables position sensing via CS1-M or DS1-M switches, though the newer MBLD uses CMSG/DMSG/EMSG sensors. The original MALD uses threaded covers, while the MBLD upgrade features a riveted rolling-packed body. Both rely on a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X175-S |
| Bore size | Ø20 mm |
| Stroke | 175 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 MBLD20X175-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 MBLD20X175-S 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 MALD20X175-S Is Used
PCB Depaneling Saw
Drives a synchronized cutting blade on a printed circuit board depaneling saw, using the twin rods to prevent blade yaw while delivering 132 N of equal cutting and retract force.
Pick-and-Place Rear Flag
Actuates a small electronic component pick-and-place head where the rear protruding rod carries a cam flag to trigger a CS1-M sensor at the precise 175 mm travel endpoint.
Label Applicator Platen
Moves a guided label applicator platen in a packaging line, relying on the double-rod anti-rotation stability to keep the pad perfectly square during the 132 N apply stroke.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175-S with MBLD20X175-S
To replace the MALD20X175-S, swap directly to the MBLD20X175-S. Confirm the 175 mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and mounting choice (FA flange or LB foot, as no back cover or SDB exists). Retain the -S magnet, but note you must upgrade to CMSG/DMSG/EMSG sensors for the new body.
Size on the equal 132 N force both ways. If you need less power, step down is not an option as 20 mm is the smallest bore. To step up, the next size is the 25 mm bore, providing 206 N at 0.5 MPa. At 175 mm stroke, ensure your guide supports the rod to prevent side-load deflection on long extensions.
Upgrade checklist
- ✓ Order the MBLD20X175-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 MBLD20X175-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X175-S FAQ
Yes, the MALD20X175-S is discontinued. The exact drop-in replacement is the MBLD20X175-S, matching the 20 mm bore, 175 mm stroke, G1/8 port, and equal force. You will need to update your position sensors from the old CS1-M/DS1-M to the newer CMSG/DMSG/EMSG switches.
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 push and 132 N pull at 0.5 MPa, 185 N push and 185 N pull at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa.
