Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X25
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X25 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 25mm 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 MBLD63X25
The AirTAC MBLD63X25 is a compact double-acting double-rod aluminum mini cylinder. Because a Ø16 mm carbon-steel rod exits both end covers, the annular piston area is identical on extend and retract, yielding 1457 N of force each way at 0.5 MPa. The short 25 mm stroke is ideal for high-force clamping or short indexing moves in tight spaces.
This SKU omits the -S code, meaning no internal magnet is fitted and it cannot accept CMSG reed or DMSG/EMSG electronic sensors for position detection. The riveted rolling-packed aluminum barrel and grease-retaining two-way piston seal ensure durable service, while the fixed rubber bumper absorbs end-of-stroke impact without acting as a position lock.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X25 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X25 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 25 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 MBLD63X25 Is Used
Stamping Press Ejection
Uses the 2040 N at 0.7 MPa to knock out stamped blanks from a progressive die, with the rear rod driving a synchronized mechanical flag to confirm ejection.
Injection Mold Core Pull
Short 25 mm stroke shifts a mold core with equal push and pull force, leveraging the twin rods to prevent torsional binding on the guide pins.
Heavy Panel Squaring
Applies 1457 N to square thick sheet metal against a back gauge before welding, using the double-rod symmetry to maintain a parallel, non-rotating clamp face.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X25 the Right Cylinder?
If 1457 N is excessive, step down to the 50 mm bore which provides 881 N at 0.5 MPa. If you need even more thrust, this 63 mm bore is the largest in the series at 297 kgf max, so no larger MBLD exists. To add adjustable air cushioning rather than relying on the fixed rubber bumper, switch to the MBLCD63 variant. Mounting is limited to Basic, FA flange, or LB foot brackets—MBLD lacks back-cover or SDB pivot options. For a drop-in replacement, match the 63 mm bore, 25 mm stroke, G1/4 port, default PT thread, and non-magnet configuration.
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 MBLD63X25 FAQ
The MBLD63X25 delivers equal force in both directions due to its twin rods: 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum theoretical 297 kgf at 1.0 MPa.
A rod protrudes from both ends, making the extend and retract areas identical for equal speed and force. The rear rod can mount a cam or flag, but because this specific SKU lacks the -S magnet, it cannot use CMSG/DMSG/EMSG sensors.
