Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 50mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50
The AirTAC MBLD50X50 is a double-acting, double-rod aluminum mini cylinder featuring a 50mm bore and 50mm stroke. Because a Ø16mm carbon-steel rod exits both end covers, the annulus area is identical on each side, delivering an equal 881N of force at 0.5 MPa on both extend and retract strokes. The riveted rolling-packed barrel and grease-retaining piston seal keep the compact body durable in tight spaces.
This SKU uses a default PT tapered port thread (G1/4) and lacks a built-in magnet (-S), meaning it cannot host CMSG or DMSG position sensors. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Overall length equals the base body dimension plus twice the stroke, requiring rear-rod clearance for a cam or position flag.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 50 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M14×1.5 |
| 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 500 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 (Ø50mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 MBLD50X50 Is Used
PCB Edge Deburring Fixture
Drives a dual-sided clamping jaw that holds a printed circuit board flat while a deburring tool passes the edge, using the equal 881N force to prevent board flex.
Textile Loom Guide Bar
Shifts a yarn guide bar from one cam track to another, using the rear protruding rod to trip a mechanical limit flag while the front rod executes the 50mm shift.
Packaging Flap Tucker
Folds corrugated carton flaps simultaneously from both sides, relying on the twin rods to keep the folding blades perfectly parallel and resist rotational twist.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50 the Right Cylinder?
Step down to the 40mm bore for 528N at 0.5 MPa, or step up to the 63mm bore for 1457N if your jig exceeds the 881N capacity of this 50mm unit. Choose the MBLCD variant if your application generates destructive kinetic energy at the end caps and requires adjustable air cushions, or switch to a single-rod MBL if you only need one-sided actuation. Mounting is limited to Basic, FA flange, or LB foot brackets—MBLD lacks back-cover or SDB pivot options.
When replacing this cylinder, match the 50mm bore, 50mm stroke, G1/4 PT port, and double-rod configuration. Because it has no magnet, external limit switches are required for position confirmation. The fixed rubber bumper absorbs shock but does not lock the load; a separate holding device must hold the rod in place without live air pressure.
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 MBLD50X50 FAQ
Because a rod occupies both sides of the piston, the push and pull forces are identical: 881N at 0.5 MPa, 1233N at 0.7 MPa, and a theoretical maximum of 180kgf at 1.0 MPa.
Unlike a single-rod cylinder where extend force exceeds pull force, the MBLD50X50 provides equal force and speed in both directions. The rear rod extension can drive a secondary mechanism or mount a position flag, but requires clearance behind the cylinder.
