This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X50-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 MALD25X50-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-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 MBLD25X50-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-S
The AirTAC MALD25X50-S is a discontinued double-acting, double-rod mini cylinder. It delivers 206 N of force in both directions at 0.5 MPa because the twin rods make the annulus area identical on each side. The exact drop-in replacement is the MBLD25X50-S, matching the 25 mm bore, 50 mm stroke, G1/8 port, and mounting.
This unit features a Ø10 mm hard-chrome rod exiting both ends, providing anti-rotation guidance and allowing a rear-mounted flag or cam. Unlike the newer riveted rolling-packed body of the MBLD, this MALD uses threaded covers. The -S magnet supports legacy CS1-M / DS1-M switches, whereas the MBLD upgrade uses CMSG / DMSG / EMSG sensors. It relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X50-S |
| Bore size | Ø25 mm |
| Stroke | 50 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 MBLD25X50-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 MBLD25X50-S matches these values.
Model Code: Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-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 MALD25X50-S Is Used
PCB Edge Guiding
Uses the 206 N equal force to square electronic boards on a conveyor without rotational drift, leveraging the twin rods for stable sliding guidance.
Dual-End Tooling Transfer
Drives a front gripper while the rear rod mounts a physical cam to trip a legacy mechanical limit switch, maximizing the 50 mm stroke layout.
Label Applicator Platen
Presses adhesive labels with consistent 289 N at 0.7 MPa, where the fixed rubber bumper safely absorbs the end-of-stroke impact without scuffing product.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-S with MBLD25X50-S
To replace your MALD25X50-S, order the MBLD25X50-S. Confirm the 50 mm stroke, G1/8 PT port, M10x1.25 rod thread, and FA or LB mounting (there is no back cover or SDB option). If sizing for a different load, step down to the 20 mm bore for 132 N each way at 0.5 MPa, or step up to the 32 mm bore for 346 N each way. At 50 mm stroke, side-load stress is minimal, but always guide the load to protect the rod seals.
Upgrade checklist
- ✓ Order the MBLD25X50-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 MBLD25X50-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X50-S FAQ
Yes, the MALD25X50-S is discontinued. The exact drop-in replacement is the MBLD25X50-S, which matches the 25 mm bore, 50 mm stroke, G1/8 port, and mounting. Note the MBLD uses a riveted body and CMSG / DMSG / EMSG sensors instead of the older CS1-M / DS1-M switches.
Because a rod exits both ends, the piston sees the same annulus area on both sides. The push and pull forces are equal: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
