This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD20X250-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD20X250-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 MALD20X250-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-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 MBLD20X250-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-S
The AirTAC MALD20X250-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, meaning push and pull forces are equal at 132 N each way at 0.5 MPa. The direct drop-in replacement is the MBLD20X250-S, matching the 20 mm bore, 250 mm stroke, G1/8 port, and mounting.
This -S variant carries a magnet for CS1-M or DS1-M switches; the MBLD replacement upgrades to CMSG / DMSG / EMSG sensors. The MALD uses threaded covers, while the MBLD features a riveted rolling-packed body. Twin rods double the bearing area and prevent rod rotation, allowing a flag or cam on the rear rod.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD20X250-S |
| Bore size | Ø20 mm |
| Stroke | 250 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 MBLD20X250-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 MBLD20X250-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-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 MALD20X250-S Is Used
PCB Edge Conveyors
Drives a synchronized dual-belt conveyor moving printed circuit boards, using the 132 N equal force and anti-rotation twin rods to prevent carriage skew over 250 mm.
Textile Yarn Guides
Shifts a yarn guide carriage back and forth across a knitting machine, relying on the rear rod to mount a cam while maintaining precise non-rotating tracking.
Vision System Shutters
Actuates a protective shutter over a machine vision lens, using the 250 mm stroke to retract the guard fully while presenting identical force in both directions.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-S with MBLD20X250-S
Replace the MALD20X250-S with the MBLD20X250-S, confirming the 20 mm bore, 250 mm stroke, G1/8 port, and FA or LB mounting. This double-rod cylinder has no back cover or SDB option. Size on the equal 132 N force at 0.5 MPa; stepping down is not an option as 20 mm is the smallest bore, but stepping up to the 25 mm bore yields 206 N at 0.5 MPa. At 250 mm stroke, twin rods resist side-load twisting better than a single rod.
Upgrade checklist
- ✓ Order the MBLD20X250-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 MBLD20X250-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD20X250-S FAQ
Yes, the MALD20X250-S is discontinued. The exact drop-in replacement is the MBLD20X250-S, which matches the 20 mm bore, 250 mm stroke, G1/8 port, and force. The MBLD upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The double-rod design yields equal force both ways: 132 N at 0.5 MPa and 185 N at 0.7 MPa, with a maximum of 27 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke impact absorption and has no adjustable cushion.
