This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X250-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X250-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 MALD25X250-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S is a double-acting, double-rod aluminum mini cylinder: a rod exits both ends of the Ø25mm bore, so push and pull force are equal. This model is discontinued — the drop-in replacement is the MBLD25X250-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S
The AirTAC MALD25X250-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, delivering equal force both ways at 206 N each direction at 0.5 MPa. The exact drop-in replacement is the MBLD25X250-S, matching the 25 mm bore, 250 mm stroke, G1/8 port, and mounting.
This unit features a 10 mm carbon-steel rod with a 20 um hard chrome plating and a heterogeneous grease-retaining seal. Unlike single-rod variants, the twin rods prevent rotation and double the bearing load for guided sliding. The -S magnet supports CS1-M / DS1-M switches, whereas the MBLD upgrade uses CMSG / DMSG / EMSG sensors and a riveted rolling-packed body instead of the MALD's threaded covers.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X250-S |
| Bore size | Ø25 mm |
| Stroke | 250 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 MBLD25X250-S carries the same ratings.
Output Force — Equal Both Ways (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | 289 N |
| Max (@1.0 MPa) | 42 kgf | |
A rod exits both ends, so the effective area — and force — is equal in both directions. The MBLD25X250-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S Is Used
PCB Edge Guide Slides
Drives a guided electronics assembly slide where the 206 N equal force and twin rods prevent chassis rotation over the 250 mm travel.
Textile Beam Shuttling
Shifts a rear-mounted cam flag on a loom beam using the extended rear rod, tracking position via the CS1-M sensor at 0.5 MPa.
Dual-Tool Pick Transfer
Mounts a secondary gripper on the opposing rod end to transfer small plastic parts simultaneously, doubling bearing capacity for stable handling.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S with MBLD25X250-S
To replace the MALD25X250-S, specify the MBLD25X250-S. Confirm the 25 mm bore, 250 mm stroke, G1/8 PT port, and M10x1.25 rod-end thread. The MBLD matches your FA or LB mounting exactly, as double-rod cylinders use no back cover or SDB. Plan to swap your CS1-M / DS1-M sensors for the MBLD's CMSG / DMSG / EMSG family.
Size on the equal force: this bore yields 206 N push and pull at 0.5 MPa. If you need less force, step down to the 20 mm bore (132 N at 0.5 MPa). If you need more, step up to the 32 mm bore (346 N at 0.5 MPa). At 250 mm stroke, guide external loads carefully to avoid rod side-load, as the fixed rubber bumper softens end impact but provides no adjustable cushioning.
Upgrade checklist
- ✓ Order the MBLD25X250-S (same bore/stroke/force)
- ✓ Force equal both ways (206 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 MBLD25X250-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X250-S FAQ
Yes, the MALD25X250-S is discontinued. The exact drop-in replacement is the MBLD25X250-S, which matches the 25 mm bore, 250 mm stroke, G1/8 port, and mounting. You will need to upgrade your switches from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG sensors, as the MBLD uses a riveted rolling-packed body instead of threaded covers.
Because the double-rod design has a rod exiting both ends, the piston sees the same annulus area in both directions. The force is equal both ways: 206 N push and 206 N pull at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. The fixed rubber bumper softens the impact at stroke ends but does not lock the load.
