This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLD25X500-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLD25X500-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 MALD25X500-S
The AirTAC Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-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 MBLD25X500-S, matching bore, stroke, force and mounting.

About the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-S
The AirTAC MALD25X500-S is a discontinued double-acting, double-rod mini cylinder. A rod exits both ends of the 25 mm bore, yielding equal force both ways at 206 N (0.5 MPa). The exact drop-in replacement is the MBLD25X500-S, matching the 500 mm stroke, G1/8 port, and mounting.
This non-standard 500 mm stroke exceeds the 300 mm catalog maximum, making it a made-to-order item. It features a fixed rubber bumper and threaded covers, whereas the MBLD upgrade uses a riveted rolling-packed body. The -S magnet supports CS1-M / DS1-M switches; the MBLD replacement transitions to CMSG / DMSG / EMSG sensors. With no back cover or SDB option, you mount directly via the body, FA flange, or LB foot.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-S Technical Specifications
| Model | Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-S |
|---|---|
| Series | MALD double-rod mini cylinder (discontinued) |
| Replacement | MBLD25X500-S |
| Bore size | Ø25 mm |
| Stroke | 500 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 MBLD25X500-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 MBLD25X500-S matches these values.

Where the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-S Is Used
PCB Edge Conveyor Tracking
Drives a synchronized dual-belt conveyor for PCB panel edge tracking. The twin rods prevent rotation during the 500 mm traverse, ensuring the rear rod carries a flag for position confirmation without binding.
Textile Beam Loom Feed
Actuates a yarn tensioning carriage on a wide loom. The equal 206 N force both ways keeps tension consistent during extension and retraction across the long 500 mm draw, while the fixed rubber bumper softens rapid cycling.
Carton Flap Folding Arm
Pushes a carton sealing flap via a rear-mounted cam tool. The double-rod design doubles the bearing load for the 500 mm stroke, and the lack of a back cover allows tight LB foot mounting inside the narrow folder frame.
Replacing the Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-S with MBLD25X500-S
To replace this MALD25X500-S, order the MBLD25X500-S. Confirm the 25 mm bore, 500 mm stroke, PT G1/8 port, M10x1.25 rod thread, and FA/LB mounting. Plan for the sensor family change: CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG on the MBLD.
Size on the equal 206 N (0.5 MPa) force. 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). Because this 500 mm stroke is long, use an external guide to prevent rod side-load and premature seal wear.
Upgrade checklist
- ✓ Order the MBLD25X500-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 MBLD25X500-S instead of this discontinued model.
Airtac MALD Aluminum Alloy Mini Cylinder MALD25X500-S FAQ
Yes, the MALD25X500-S is discontinued. The exact drop-in replacement is the MBLD25X500-S, which matches the 25 mm bore, 500 mm stroke, G1/8 port, and mounting. The MBLD upgrades the construction to a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors instead of the older CS1-M / DS1-M switches.
Force is equal both ways because the twin rods occupy the same annulus area on each side of the piston. The ratings are: 206 N push and 206 N pull at 0.5 MPa; 289 N push and 289 N pull at 0.7 MPa; and a maximum force of 42 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion or a load-holding lock.
