Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X40
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X40 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 40mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X40
The AirTAC MBLD20X40 is a compact double-acting double-rod aluminum mini cylinder. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 132 N of force each way at 0.5 MPa. This 40 mm stroke suits short transfer and gripping tasks where symmetry matters. It features a fixed rubber bumper and a riveted rolling-packed barrel.
With no magnet suffix, this SKU cannot accept a CMSG or DMSG position sensor. The twin Ø8 mm hard-chrome rods provide dual-side guidance to resist rotation, while the rear rod end can drive a secondary mechanism or cam. Note that overall length equals A + 2 x stroke, so you must leave rear-rod clearance in your layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X40 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X40 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 40 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 MBLD20X40 Is Used
PCB Pick-and-Place
Uses the 132 N equal thrust and 40 mm stroke to lift delicate circuit boards, relying on the twin rods to prevent gripper twist during vertical transfers.
Label Dispenser Cam
Mounts a cam on the rear rod end to trigger a mechanical valve, using the synchronized front and rear extension to cut labels at exact intervals.
Connector Seating Press
Applies 185 N at 0.7 MPa to seat electronic connectors evenly, with the double-rod geometry keeping the pressing head square to the socket.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X40 the Right Cylinder?
If you need less push, stepping down is not an option as 20 mm is the smallest bore. If your payload requires more force, step up to the 25 mm bore, which provides 206 N at 0.5 MPa. Unlike the single-rod MBL, this MBLD gives equal extend and retract thrust, and unlike the MBLCD, it uses a fixed rubber bumper rather than an adjustable air cushion.
Mounting is limited to Basic, FA flange, or LB foot; there is no back-cover or SDB pivot option for this double-rod body. The plain bumper softens end impact but does not lock the rod—position holding requires live air or an external lock. Replacement match: 20 mm bore, 40 mm stroke, G1/8 port, PT thread, no 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 MBLD20X40 FAQ
Because it is a double-rod cylinder, the force is identical in both directions: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa. There is no larger push figure; extend equals retract.
The twin rods provide equal force and speed both ways, plus better resistance to side-load rotation. The rear protruding rod can also drive a second mechanism. However, this specific SKU lacks the -S magnet, so it cannot accept CMSG or DMSG electronic sensors.
