Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 400mm 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 MBLD63X400S
The AirTAC MBLD63X400S is a double-acting, double-rod aluminum mini cylinder featuring a 63mm bore and 400mm stroke. Because a Ø16mm carbon-steel rod with 20μm hard-chrome plating exits both end covers, the annulus piston area is identical on extend and retract. This yields equal force and speed in both directions, generating 1457N at 0.5MPa and 2040N at 0.7MPa. The built-in magnet (-S) enables position detection via CMSG reed or DMSG/EMSG electronic switches.
This 400mm stroke provides extended traverse for pushing heavy jigs or transferring substantial loads. The riveted rolling-packed aluminum barrel and two-way grease-retaining piston seal ensure compact durability in tight spaces. Impact at the stroke ends is softened by a fixed rubber bumper. Overall length equals A plus 2x stroke, meaning the rear rod protrudes significantly and requires dedicated clearance for a secondary cam or position flag.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 400 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 MBLD63X400S Is Used
Injection Mold Ejection
Drives heavy mold ejector pins over 400mm to strip thick-walled parts, using the 1457N both-way force to ensure positive retraction without spring lag.
Pallet Transfer Line
Shifts loaded 63mm pallets between machining centers, mounting a position flag on the rear rod to trigger a downstream DMSG sensor at full extension.
Bending Press Tooling
Applies 2040N at 0.7MPa to actuate a secondary bending jaw, utilizing the equal push/pull force to release tension on the workpiece during the retract cycle.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X400S the Right Cylinder?
When sizing this 63mm bore, stepping down to the 50mm bore yields 881N at 0.5MPa, while the 63mm is the largest available in this series, offering a maximum theoretical 297kgf at 1.0MPa. If your application requires adjustable air cushioning rather than a fixed rubber bumper, choose the MBLCD variant; for single-rod setups, select the MBL. Mounting is limited to Basic, FA flange, or LB foot brackets—MBLD lacks back-cover or SDB pivot options. To replace this SKU, match the 63mm bore, 400mm stroke, G1/4 port, PT thread, and -S magnet. At 400mm stroke, the twin rods still require an external guide to prevent side-load bending, and the cylinder cannot hold position without live air.
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 MBLD63X400S FAQ
Because the double-rod design has equal piston area on both sides, force is identical in both directions: 1457N at 0.5MPa, 2040N at 0.7MPa, and a maximum theoretical 297kgf at 1.0MPa.
A rod exits both ends, making extend and retract forces equal and allowing you to mount a secondary cam or position flag on the rear rod. The -S code means a magnet is built in for CMSG reed or DMSG/EMSG electronic sensors.
