Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X200S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X200S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 200mm 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 MBLD63X200S
The AirTAC MBLD63X200S is a double-acting, double-rod aluminum mini cylinder featuring a 63 mm bore and 200 mm stroke. Because a Ø16 mm carbon-steel rod exits both end covers, the annulus piston area is identical on extend and retract. This yields exactly 1457 N of force at 0.5 MPa in both directions (2040 N at 0.7 MPa), ensuring perfectly balanced push and pull dynamics for heavy mid-stroke work. The built-in magnet (-S) enables position detection.
A defining mechanical advantage of this twin-rod layout is the ability to mount a primary workpiece on the front rod while attaching a position flag, cam, or secondary mechanism to the rear rod. The dual protruding rods also provide inherent anti-rotation guidance superior to a single-rod unit. Keep in mind the overall length equals the base body length plus 2 x 200 mm, so you must leave physical clearance at the rear for the extending rod. The riveted rolling-packed aluminum barrel houses a fixed rubber bumper to soften end-of-stroke impacts.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X200S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X200S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 200 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 MBLD63X200S Is Used
Injection Mold Ejection
Drives an ejection plate from the front rod while the rear rod trips a heavy-duty limit switch, using the 1457 N bidirectional force to safely strip parts from injection molds.
Printed Circuit Board Scoring
Guides a scoring blade across PCB panels with equal push and pull speed, relying on the twin-rod anti-rotation properties to prevent blade yaw during 200 mm traversing cuts.
Pallet Transfer Indexing
Uses the rear protruding rod as a cam to actuate a secondary pneumatic diverter valve, synchronizing a 200 mm pallet push cycle in packaging lines.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X200S the Right Cylinder?
If your payload is lighter, stepping down to the 50 mm bore drops the bidirectional force to 881 N at 0.5 MPa, whereas this 63 mm bore provides 1457 N. As the largest available MBLD size, there is no larger standard option for higher force demands. The fixed rubber bumper suits general cycling, but if your 200 mm stroke generates high kinetic energy at the ends, consider the MBLCD variant which adds adjustable air cushioning. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. To replace this unit, match the 63 mm bore, 200 mm stroke, G1/4 port, PT thread, and -S magnet. Note that a plain MBLD will drift and cannot hold position without live air pressure—the bumper is not a locking device.
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 MBLD63X200S FAQ
Because the double-rod design has equal piston area on both sides, extend and retract 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.
The -S code indicates a built-in magnet for rod position sensing. It is compatible with AirTAC CMSG reed switches, as well as DMSG and EMSG electronic solid-state sensors. Without the -S code, the cylinder cannot accept any sensor switches.
