Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X225S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X225S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 225mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 1458 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X225S
The AirTAC MBLD63X225S is a double-acting, double-rod aluminum mini cylinder featuring a 63mm bore and 225mm stroke. A single piston drives a Ø16mm hard-chrome carbon-steel rod out of both end covers, yielding exactly 1457N of force at 0.5 MPa on both extend and retract strokes. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track position. It uses a G1/4 port and M14x1.5 rod-end threads.
Because the rear rod protrudes during operation, you must leave rear-end clearance matching the 225mm stroke. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. This design provides twin-rod anti-rotation guidance and allows mounting a cam or position flag on the rear rod end to trigger secondary mechanisms.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X225S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X225S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 225 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 (Ø63mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 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 MBLD63X225S Is Used
Injection Mold Ejection
Drives an ejection plate with 1457N of equal force on both strokes, using the rear rod end to actuate a return limit switch on large molding presses.
Packaging Flap Folding
Folds heavy cardboard carton flaps synchronously; the twin-rod design prevents torsional twist during rapid 225mm travel, ensuring consistent sealing.
PCB Conveyor Sorting
Diverts populated circuit boards at high speed, mounting a physical position flag on the rear protruding rod to confirm gate movement to the PLC.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X225S the Right Cylinder?
For 1457N of bidirectional force, this 63mm bore is the largest in the MBLD range. If your application needs less force, stepping down to the 50mm bore yields 881N at 0.5 MPa. Mounting is limited to Basic, FA flange, or LB foot styles; the MBLD has no SDB pivot or back-cover option. The fixed rubber bumper softens end-stop impact but is not an adjustable air cushion—choose the MBLCD variant if you need adjustable cushioning.
To replace this cylinder, match the 63mm bore, 225mm stroke, G1/4 port, PT thread, and -S magnet. At 225mm of stroke, the Ø16mm twin rods still require an external guide to prevent side-load bending, as the rods alone cannot support heavy off-center loads. Note that a plain MBLD does not hold position without live air; the rod will drift, so use an external locking device for static holding.
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 MBLD63X225S FAQ
Because the rod exits both ends, the annulus area is identical on both sides, providing equal push and pull force. It delivers 1457N at 0.5 MPa and 2040N at 0.7 MPa, with a maximum theoretical output of 297kgf at 1.0 MPa.
The twin rods provide equal extend/retract force and better resistance to rotational twist than a single rod. The -S code means a built-in magnet is included, allowing you to mount AirTAC CMSG reed switches or DMSG/EMSG solid-state sensors directly to detect piston position.
