Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X40
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X40 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 40mm 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 MBLD25X40
The AirTAC MBLD25X40 is a compact double-acting double-rod aluminum mini cylinder. A single piston drives a Ø10 mm carbon-steel rod out of both end covers, yielding equal effective annulus areas. Consequently, it generates 206 N of force in both extend and retract directions at 0.5 MPa. The 40 mm stroke is well-suited for short indexing and ejection tasks.
This configuration features a PT tapered port thread and a fixed rubber bumper at each end to soften impact. Because the rear rod protrudes continuously, you can mount a position flag or cam on the opposite side to trigger a remote mechanical switch. Note that this specific SKU lacks a built-in magnet, meaning it cannot host CMSG, DMSG, or EMSG electronic sensors for automated position feedback.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X40 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X40 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 40 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 MBLD25X40 Is Used
PCB Depaneling Saw
Drives a circular blade forward and back with equal 206 N force, using the rear rod end to push a secondary dust extraction nozzle simultaneously.
IC Tube Transfer
Indexes surface-mount component tubes by 40 mm, leveraging the twin rods to keep the sliding carrier perfectly aligned and twist-free during shuttle movements.
Label Applicator Platen
Presses a label onto a moving carton and retracts at identical speed, with the protruding rear rod mechanically tripping a physical limit switch to confirm cycle completion.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X40 the Right Cylinder?
If your drive requires less force, stepping down to the MBLD20X40 provides 132 N at 0.5 MPa, while moving up to the MBLD32X40 increases output to 346 N. Unlike the single-rod MBL, this twin-rod design ensures equal push and pull forces while resisting torsional twist. Mounting is limited to Basic, FA flange, or LB foot brackets; no SDB pivot or back-cover options exist for the double-rod series. For applications needing adjustable end-cushioning rather than fixed rubber bumpers, consider the MBLCD variant. To replace this unit, match the 25 mm bore, 40 mm stroke, G1/8 port, PT thread, and lack of a magnet.
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 MBLD25X40 FAQ
Because a rod exits both ends, the effective piston area is identical in both directions. This yields an equal push and pull force of 206 N at 0.5 MPa and 289 N at 0.7 MPa, with a maximum theoretical output of 42 kgf at 1.0 MPa.
A double-rod cylinder provides equal extend and retract forces and allows you to mount a cam or secondary tool on the rear rod. This specific MBLD25X40 SKU has no built-in magnet (-S) and therefore cannot accept CMSG reed or DMSG/EMSG electronic sensors; you must rely on external mechanical flags for position detection.
