Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X40S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X40S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 40mm 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 MBLD63X40S
The AirTAC MBLD63X40S is a compact double-acting double-rod aluminum mini cylinder featuring a 63mm bore and 40mm stroke. A carbon-steel rod protrudes from both end covers, yielding equal effective annulus areas. This means push and pull forces are identical, delivering 1457 N each way at 0.5 MPa and 2040 N at 0.7 MPa. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track piston position. Equipped with a G1/4 port and M14x1.5 rod-end thread, it suits high-force short-stroke tasks.
Because a rod exits both ends, you can mount a workpiece on the front and a mechanical cam or position flag on the rear. The riveted rolling-packed aluminum barrel and grease-retaining piston seal ensure reliable operation, while the fixed rubber bumper softens end-of-stroke impact. Remember that overall length equals the base body length plus twice the stroke, so you must leave clearance for the rear rod. This base MBLD uses a fixed rubber bumper, not the adjustable air cushion found in the MBLCD variant.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X40S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X40S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 40 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 MBLD63X40S Is Used
Injection Mold Ejection
Drives a 1457N dual-sided ejection plate in plastic injection molding, using the rear rod to trip a limit switch confirming full retraction.
PCB Conveyor Diverter
Powers a dual-sided sorting gate on an SMT line, leveraging equal extend and retract speeds to maintain synchronous panel routing.
Textile Calender Guide
Acts as an anti-rotation tensioning arm in a fabric calender machine, keeping the web aligned using both rod ends for balanced guidance.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X40S the Right Cylinder?
For 40mm stroke applications, step down to the 50mm bore (881 N at 0.5 MPa) if your load is lighter, or step up to this 63mm bore (1457 N at 0.5 MPa) when you need maximum push and pull force in a compact footprint. Choose the single-rod MBL if you only need standard push force and lack rear-rod clearance, or pick the MBLCD if high cycle rates demand adjustable air cushioning. Mounting is limited to Basic, FA flange, or LB foot brackets; MBLD has no back-cover or SDB pivot option. A plain MBLD does not hold position without live air, as the bumper is not a lock. To replace this unit, match the 63mm bore, 40mm stroke, G1/4 port, PT thread, and the -S 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 MBLD63X40S FAQ
Because the double-rod design has equal annulus areas on both sides, output force is identical in both directions: 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum theoretical 297 kgf at 1.0 MPa.
The -S code indicates a built-in magnet for position sensing. It is compatible with AirTAC CMSG reed switches and DMSG/EMSG electronic solid-state sensors. Without the -S code, a SKU cannot accept any sensor switch.
