This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X175-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X175-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 MALD25X175-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-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 MBLD25X175-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-S
The AirTAC MALD25X175-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, yielding equal push and pull force of 206 N each way at 0.5 MPa. The exact drop-in replacement is the MBLD25X175-S, matching the 25 mm bore, 175 mm stroke, G1/8 port, and FA/LB mounting.
This -S variant carries a magnet for CS1-M or DS1-M switches; the MBLD successor upgrades to CMSG/DMSG/EMSG sensors. The MALD uses threaded covers, whereas the MBLD features a riveted rolling-packed body. Twin rods resist rotation, double the bearing load, and allow a rear flag or cam. There is no back cover or SDB option; mount via the body, FA flange, or LB foot.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X175-S |
| Bore size | Ø25 mm |
| Stroke | 175 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 MBLD25X175-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 MBLD25X175-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-S Is Used
PCB Pick-and-Place
Drives a dual-vacuum head moving electronic components. The twin rods prevent chassis rotation during rapid 206 N vertical placement, while the rear rod mounts a physical stroke-limit cam.
Textile Yarn Guide
Oscillates a thread guide carriage across a loom. Equal push and pull force ensures consistent tensioning in both travel directions without momentum drift, using the 175 mm stroke.
Packaging Flap Folder
Folds cardboard carton flaps synchronously. The second opposing rod actuates a secondary tucking blade at the opposite end, operating within the 0.1-1.0 MPa pressure range.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-S with MBLD25X175-S
To replace the MALD25X175-S, order the MBLD25X175-S. Confirm the 25 mm bore, 175 mm stroke, G1/8 port, PT thread, FA/LB mount, and the -S magnet (noting the switch family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Size using the equal-both-ways force: 206 N at 0.5 MPa. To step down, the 20 mm bore provides 132 N. To step up, the 32 mm bore yields 346 N. For this 175 mm stroke, ensure adequate side-load guidance to protect the 10 mm rods.
Upgrade checklist
- ✓ Order the MBLD25X175-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 MBLD25X175-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X175-S FAQ
Yes, the MALD25X175-S is discontinued. The exact drop-in replacement is the MBLD25X175-S. It matches the 25 mm bore, 175 mm stroke, G1/8 port, and FA/LB mounting. The upgrade transitions from threaded covers to a riveted rolling-packed body, and the -S magnet changes from CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors.
Because a rod exits both ends, the piston sees the same annulus area on extension and retraction, making push and pull force equal. The exact figures are: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. End-of-stroke impact is absorbed by a fixed rubber bumper, not an adjustable cushion.
