Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 20mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 206 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20
The AirTAC MBLD25X20 is a compact double-acting double-rod aluminum mini cylinder engineered to deliver 206 N of force in both extend and retract directions at 0.5 MPa. Because a Ø10 mm carbon-steel rod protrudes from both end covers, the annular piston area is identical on each side, ensuring perfectly balanced thrust and speed for your 20 mm stroke application.
This riveted rolling-packed barrel features a fixed rubber bumper to soften end-of-stroke impacts and a grease-retaining piston seal for long service life. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The rear rod end is ideal for mounting a mechanical cam or position flag to trigger external limits, while the twin rods provide better resistance to torsional twist than a single-rod unit.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 20 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 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 overall length = A + 2 × stroke — leave clearance for the rear rod. MBLD/MBLCD mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Output Force (Ø25mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
A rod on both piston faces makes the annulus area equal, so extend and retract force (and speed) are the same. Actual usable force is lower due to friction.

Where the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20 Is Used
PCB Stencil Wiping
Drives a 20 mm stroke wiper blade across solder paste stencils, using the rear rod to trigger a pneumatic blow-off valve simultaneously.
Chip Ejector Mechanism
Pushes defective microchips off a test socket with 206 N of force, retracting at the exact same speed to maintain cycle timing.
Film Edge Guide Flag
Uses the protruding rear rod to mechanically trip a limit switch for web tracking, ensuring equal force during extension and retraction.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20 the Right Cylinder?
If your mechanism requires slightly less thrust, step down to the MBLD20X20, which yields 132 N both ways at 0.5 MPa. For heavier loads, step up to the MBLD32X20, providing 346 N both ways. Unlike the single-rod MBL variant, this double-rod design ensures equal push and pull forces, making it ideal for symmetrical operations. If your cycle speeds demand adjustable end-cushioning to prevent shock, consider the MBLCD variant instead, as the base MBLD only offers a fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot brackets; no SDB pivot or back-cover options exist. To replace this unit, match the 25 mm bore, 20 mm stroke, G1/8 port, PT thread, and non-magnet configuration. Remember that a plain MBLD does not hold position without continuous air pressure—the rod will drift if supply drops.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Rear-rod clearance (length = A + 2 × stroke)
- ✓ Mounting: Basic / FA / LB only
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Leave clearance for the rear rod (length = A + 2 × stroke).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X20 FAQ
The MBLD25X20 delivers equal force in both directions due to its double-rod design. It outputs 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa.
A double-rod cylinder has a piston rod exiting both end covers, creating equal annulus areas on both sides. This results in identical extend and retract forces and speeds, unlike a single-rod MBL. The rear rod can also mount a cam or flag, though this non-S SKU cannot fit position sensors.
