Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 75mm 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 MBLD63X75
The AirTAC MBLD63X75 is a double-acting, double-rod aluminum mini cylinder featuring a 63 mm bore and 75 mm stroke. Because a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating exits both end covers, the annulus area is identical on each side. This yields exactly 1457 N of force at 0.5 MPa on both extend and retract strokes, preventing the speed and force asymmetry found in single-rod designs. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal ensure robust, long-term lubrication for heavy-duty cycles.
This 75 mm travel length is well-suited for mid-range transfer and pressing tasks requiring high bilateral stability. A fixed rubber bumper absorbs end-of-travel impact inside the compact body, though it is not an adjustable air cushion (choose MBLCD for that feature). Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing. Furthermore, the twin rods protrude from both ends, so you must leave rear-rod clearance in your machine layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 75 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 MBLD63X75 Is Used
PCB Stacker Escapement
Drives a dual-side stacker arm in a PCB handling line, using the 1457 N bilateral force to lift and lower populated boards without the rotational torque shift of a single rod.
Bottle Divert Gate
Actuates a heavy diverting gate on a packaging conveyor, utilizing the twin-rod anti-rotation to keep the guide plate perfectly aligned across the 75 mm stroke.
Press Pin Insertion
Presses connector pins into housings on an electronics assembly fixture, using the rear rod end to simultaneously drive a mechanical position flag for a hard-stop cam.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75 the Right Cylinder?
To properly size this cylinder, consider stepping down to the 50 mm bore if your application only requires 881 N at 0.5 MPa, or stepping up if you need more than the 297 kgf maximum theoretical force this 63 mm bore provides at 1.0 MPa. The 63 mm bore uses a G1/4 port, matching the flow requirements of higher-force cycles. When replacing this unit, verify the 75 mm stroke, G1/4 port, PT thread form, and Basic mounting style. This SKU lacks the -S magnet, so it cannot accept a sensor switch.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for the double-rod type. Keep in mind that a plain MBLD does not hold position without live air—rod drift will occur if air pressure drops. The fixed rubber bumper softens impact but does not lock the load, so external locking mechanisms are required for vertical or safety-critical 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 MBLD63X75 FAQ
Because the MBLD63X75 is a double-rod cylinder, the extend and retract forces are perfectly equal. It outputs 1457 N at 0.5 MPa and 2040 N at 0.7 MPa in both directions. The maximum theoretical force is 297 kgf at 1.0 MPa.
No, this specific MBLD63X75 SKU does not have the -S code, meaning it lacks a built-in magnet and cannot be used with CMSG, DMSG, or EMSG electronic switches. The twin rods also mean a rod exits the rear cover, which is useful for driving a mechanical cam or external flag, but you must leave rear clearance in your design.
