This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X170S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X170S 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 MALD25X170S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X170S 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 MBLD25X170S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X170S
The AirTAC MALD25X170S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, giving 206 N of equal force both ways at 0.5 MPa. The exact drop-in replacement is the MBLD25X170S, matching the 25 mm bore, 170 mm stroke, G1/8 port, and mounting.
This twin-rod layout resists rotation and doubles the bearing load for guided slide applications. The -S magnet works with CS1-M / DS1-M switches, while the MBLD upgrade moves to CMSG / DMSG / EMSG sensors and a riveted rolling-packed body instead of threaded covers. End-of-travel impact is absorbed by a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X170S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X170S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X170S |
| Bore size | Ø25 mm |
| Stroke | 170 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 MBLD25X170S 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 MBLD25X170S 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 MALD25X170S Is Used
PCB Edge Deburring
Drives a dual-sided deburring blade on a printed circuit board line, using the 206 N equal force and twin rods to prevent cutter rotation during the pull stroke.
Shuttle Conveyor Transfer
Mounts a rear cam flag on the second rod to trigger a reed switch on a packaging shuttle, relying on the 170 mm stroke to push cartons between belt lanes.
Textile Loom Take-Up
Actuates a fabric tensioning jaw on a weaving loom, where the fixed rubber bumper absorbs the 289 N end impact at 0.7 MPa without marking the material.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X170S with MBLD25X170S
Replace this MALD25X170S directly with the MBLD25X170S. Confirm the 25 mm bore, 170 mm stroke, M10x1.25 rod-end thread, and FA or LB mounting. Because it is a double-rod unit, there is no back-cover or SDB code. The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG.
Size on the equal-both-ways force: if 206 N at 0.5 MPa is too low, step up to the 32 mm bore for 346 N; if you need less force, step down to the 20 mm bore for 132 N. With a 170 mm stroke, use external guides to prevent rod side-load and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD25X170S (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 MBLD25X170S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X170S FAQ
Yes, the MALD25X170S is discontinued. The exact drop-in replacement is the MBLD25X170S, which matches the 25 mm bore, 170 mm stroke, G1/8 port, and equal-both-ways force. You will need to upgrade your sensors from CS1-M / DS1-M to the CMSG / DMSG / EMSG family.
The force is 206 N at 0.5 MPa and 289 N at 0.7 MPa, with a maximum of 42 kgf at 1.0 MPa. Because a rod exits both ends of the bore, the piston sees the same annulus area on each side, making push and pull force identical. There is no larger single-rod push value.
