Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 400mm 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 MBLD63X400
The AirTAC MBLD63X400 is a double-acting, double-rod aluminum mini cylinder featuring a 63mm bore and 400mm stroke. Because a Ø16mm carbon-steel rod protrudes from both end covers, the annulus piston area is identical on extend and retract, yielding equal force and speed in both directions at 1457 N at 0.5 MPa. This 400mm travel suits extended indexing on automated assembly lines, while the riveted rolling-packed barrel keeps the overall envelope compact for tight machine cavities.
This specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without modification or replacement. Impact is managed by a fixed rubber bumper at the stroke ends—it is not an adjustable air cushion, nor does it lock the rod in place when air is removed. The rear rod offers a secondary mounting point for a position flag or cam, but because overall length equals the base body plus twice the stroke, you must leave ample rear clearance for the protruding shaft.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 400 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 MBLD63X400 Is Used
Injection Mold Ejection
Drives a 400mm ejector pin plate on a plastics molding press, using the 1457 N equal both-way force to push parts out steadily and retract the plate without speed mismatch.
Textile Loom Beat-Up
Actuates a 400mm traversing reed mechanism, utilizing the twin-rod design to mount a yarn tensioning cam on the rear shaft while maintaining anti-rotation stability.
CNC Conveyor Indexing
Shifts a 63mm bore indexing carriage 400mm to load raw bar stock into a CNC lathe, relying on the rear rod to push a mechanical limit flag for sequence timing.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400 the Right Cylinder?
When sizing this 63mm bore, stepping down to the 50mm MBLD variant reduces your equal both-way force to 881 N at 0.5 MPa, while the 63mm is the largest available bore in this series offering 1457 N. For high-kinetic-energy cycles, consider the MBLCD variant which adds adjustable air cushioning, whereas the base MBLD relies solely on fixed rubber bumpers. Mounting is restricted to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. To replace this unit, match the 63mm bore, 400mm stroke, G1/4 port, PT thread, and lack of -S magnet. At 400mm of travel, the small 16mm rod is highly susceptible to bending under side loads—always use an external linear guide to prevent premature seal wear and rod damage.
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 MBLD63X400 FAQ
Because the double-rod design has equal annulus piston area on both sides, the extend and retract forces are identical: 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum theoretical 297 kgf at 1.0 MPa.
A single-rod cylinder has unequal push/pull forces due to the rod occupying one side, but the MBLD63X400 has a rod exiting both ends, making force and speed perfectly symmetrical. This allows the rear rod to drive a secondary mechanism or flag, though this SKU lacks a built-in magnet for sensor tracking.
