This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X350-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X350-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 MALD25X350-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X350-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 MBLD25X350-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X350-S
The AirTAC MALD25X350-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends, so the annulus area is identical on extension and retraction. This gives equal force both ways at 206 N each direction at 0.5 MPa. The exact drop-in replacement is the MBLD25X350-S, matching the 25 mm bore, 350 mm stroke, G1/8 port and mounting.
This -S SKU includes a magnet for CS1-M or DS1-M reed switches. The MBLD upgrade switches to CMSG, DMSG or EMSG sensors and uses a riveted rolling-packed body instead of the original threaded covers. The 350 mm stroke is a non-standard, made-to-order length exceeding the 300 mm max standard for this bore. It uses fixed rubber bumpers, not adjustable cushions, and mounts via FA or LB without a back cover.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X350-S Technical Specifications

|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X350-S |
| Bore size | Ø25 mm |
| Stroke | 350 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 MBLD25X350-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 MBLD25X350-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X350-S Is Used
PCB Edge-Guiding
Drives a symmetrical edge-guide arm on a conveyor pick-and-place. The twin rods prevent yaw during the 350 mm travel, while the 206 N equal force keeps delicate fiberglass boards centered without snapping.
Film Web Tracking
Actuates a pivoting guide roller on a packaging film line. The rear rod carries a cam for a CS1-M reed switch, confirming the 350 mm non-standard stroke position while the 289 N force at 0.7 MPa holds web tension.
Dual-Side Clamping
Synchronizes two opposing clamp jaws on a small-parts machining fixture. Equal push and pull force at 206 N ensures both jaws grip with identical pressure, preventing part deformation during milling.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X350-S with MBLD25X350-S
To replace the MALD25X350-S, specify the MBLD25X350-S. Confirm the 25 mm bore, 350 mm non-standard stroke, G1/8 PT port, M10x1.25 rod-end thread, and FA or LB mounting. There is no back cover or SDB option on this double-rod body. Because the -S magnet is present, upgrade your CS1-M or DS1-M switches to the MBLD-compatible CMSG, DMSG or EMSG sensor family.
Size strictly on the equal force: 206 N at 0.5 MPa and 289 N at 0.7 MPa each way. To step down, the 20 mm bore provides 132 N at 0.5 MPa. To step up, the 32 mm bore yields 346 N at 0.5 MPa. At 350 mm stroke, twin rods add bearing support, but you must guide the load to prevent side-load bending on long extensions.
Upgrade checklist
- ✓ Order the MBLD25X350-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 MBLD25X350-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X350-S FAQ
Yes, the MALD25X350-S is discontinued. The exact drop-in replacement is the MBLD25X350-S, matching the 25 mm bore, 350 mm stroke, G1/8 port and mounting. The MBLD uses a riveted rolling-packed body instead of threaded covers, and you must swap CS1-M or DS1-M switches for CMSG, DMSG or EMSG sensors.
Force is equal both ways due to the double-rod design: 206 N at 0.5 MPa and 289 N at 0.7 MPa in both directions, with a maximum of 42 kgf at 1.0 MPa. It uses fixed rubber bumpers for end-of-stroke impact absorption; it has no adjustable cushion and provides no load holding on air loss.
