Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X350
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X350 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 350mm 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 MBLD63X350
The AirTAC MBLD63X350 is a double-acting, double-rod aluminum mini cylinder engineered for applications requiring 1457 N of equal force in both extend and retract directions at 0.5 MPa. Because a Ø16 mm carbon-steel rod with a 20 um hard-chrome plating exits both end covers, the annulus area is identical on each side, ensuring perfectly balanced push and pull speeds. A 350 mm stroke is well-suited for traversing large machine envelopes, and the riveted rolling-packed barrel keeps the overall footprint compact.
This configuration uses a fixed rubber bumper at the stroke ends to soften impact rather than an adjustable air cushion. The overall length equals A + 2 x stroke, meaning the rear rod protrudes significantly and requires dedicated clearance for a cam or position flag. Note that this specific SKU lacks a built-in magnet, meaning it cannot accept CMSG, DMSG, or EMSG electronic position sensors without a physical modification.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X350 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 350 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 MBLD63X350 Is Used
Injection Mold Ejection
Drives a dual-sided ejection plate in an injection molding cell, using the 1457 N equal both-way force to strip parts cleanly without rotational binding.
Indexing Conveyor Gate
Shifts a heavy diverter gate 350 mm across a packaging line, using the rear rod end to mount a mechanical cam that triggers a downstream limit switch.
Textile Calendering
Applies constant 2040 N clamping pressure at 0.7 MPa on a textile calendering roller, ensuring uniform fabric tension via twin-rod anti-rotation guidance.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X350 the Right Cylinder?
When sizing this 63 mm bore model, stepping down to the 50 mm bore yields 881 N at 0.5 MPa, while the 63 mm bore is the largest available in the MBLD range, delivering 2040 N at 0.7 MPa and a maximum theoretical 297 kgf at 1.0 MPa. If your application requires adjustable pneumatic cushioning to absorb heavy end-of-stroke kinetic energy at this stroke length, step up to the MBLCD variant. For single-ended tasks where rear-rod clearance is impossible, the standard single-rod MBL is the correct choice.
Mounting is strictly limited to Basic, FA flange, or LB foot brackets; the MBLD design physically omits the SDB pivot and back-cover options. Because the 350 mm stroke is substantial, the 8-16 mm rod diameter is vulnerable to side-load buckling, so an external guide rail is strongly recommended to prevent rod bending. To replace this unit, match the 63 mm bore, 350 mm stroke, G1/4 port, PT thread form, 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 MBLD63X350 FAQ
Because the rod exits both ends, push and pull 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. This specific SKU does not have a built-in magnet, so it cannot be used with AirTAC CMSG, DMSG, or EMSG position sensors.
A double-rod cylinder provides equal force and speed in both directions because the piston area is identical on both sides. It also allows you to mount a workpiece on the front rod and a cam, guide, or secondary tool on the rear rod, though it requires clearance for the rear rod to protrude.
