Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X300
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X300 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 300mm 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 MBLD63X300
The AirTAC MBLD63X300 is a double-acting, double-rod aluminum mini cylinder engineered for heavy-duty push-pull cycles. Because a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating exits both end covers, the annulus area is identical on extend and retract. This yields exactly 1457 N of force at 0.5 MPa and 2040 N at 0.7 MPa in both directions, ensuring perfectly balanced motion for a 300 mm stroke. The riveted rolling-packed barrel keeps the compact body rigid in tight machine spaces.
A defining mechanical trait of this twin-rod layout is the ability to mount a primary workpiece on the front rod and a secondary guide, cam, or position flag on the rear rod, which protrudes by 300 mm and requires rear clearance. The overall length equals A plus twice the stroke. This SKU uses a fixed rubber bumper to soften end-of-travel impact (adjustable cushion is the MBLCD variant) and has no built-in magnet, meaning it cannot host a CMSG, DMSG, or EMSG position sensor.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X300 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X300 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 300 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 MBLD63X300 Is Used
Injection Mold Ejection
Drives a 300 mm ejector pin array on a 200-ton injection molding press, using the 1457 N both-way force to push parts clear and retract the plate simultaneously.
Indexing Drum Transfer
Powering a heavy-duty rotary indexing drum, the twin rods prevent torsional twist during 300 mm travel while shifting 60 kg metal castings between CNC stations.
PCB Stacker Alignment
Synchronizes a vertical stacker elevator in an electronics assembly line, using the rear rod end to mechanically trip a mechanical limit flag at full extension.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X300 the Right Cylinder?
For 300 mm strokes, the MBLD63 sits at the top of the standard range with a maximum 297 kgf theoretical load at 1.0 MPa. If you need less force, step down to the 50 mm bore, which provides 881 N at 0.5 MPa; there is no larger standard bore in the MBLD mini line. Because this 300 mm stroke pushes a small 16 mm rod, external side-load guidance is mandatory to prevent rod bending and premature seal wear. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. If you need adjustable air cushioning rather than fixed rubber bumpers, select the MBLCD63 variant. To replace this unit, match the 63 mm bore, 300 mm stroke, G1/4 port, PT thread, and confirm no magnet is required.
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 MBLD63X300 FAQ
The double-rod design provides equal force both ways: 1457 N at 0.5 MPa and 2040 N at 0.7 MPa, with a maximum theoretical load of 297 kgf at 1.0 MPa. The 300 mm stroke is the maximum standard stroke for the 63 mm bore.
Unlike a single-rod MBL cylinder, the MBLD63X300 has a rod exiting both ends, making extend and retract forces equal. This allows you to mount a workpiece on the front rod and a cam or guide on the rear rod, but requires rear clearance. Note that this specific SKU lacks a built-in magnet, so no reed or electronic sensor can be fitted.
