Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X50
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X50 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 50mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X50
The AirTAC MBLD20X50 is a compact double-acting double-rod aluminum mini cylinder delivering 132 N of force in both extend and retract directions at 0.5 MPa. Because the Ø8 mm piston rod passes through both end covers, the annulus area is identical on each side, yielding perfectly symmetrical push and pull dynamics. The 50 mm stroke is well-suited for short-indexing tasks in tight electronics or packaging machinery.
This SKU features a PT tapered port thread and lacks the -S magnet suffix, meaning it cannot accept AirTAC CMSG, DMSG, or EMSG position sensors. A fixed rubber bumper absorbs end-of-stroke impact, while the riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod ensure durable, low-friction operation. Overall length equals A + 2 x stroke, requiring rear-rod clearance for the protruding tail.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X50 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X50 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 50 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 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 (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 MBLD20X50 Is Used
PCB Depaneling Saw Feed
Drives a short 50 mm cut stroke with equal 132 N push and pull force, using the rear rod end to mount a physical limit flag for saw blade depth tracking.
Label Applicator Transfer
Uses the twin-rod anti-rotation property to keep a small vacuum pad perfectly aligned during 50 mm extend and retract cycles without twisting.
Connector Insertion Jig
Provides symmetrical thrust for pressing delicate electronic pins, with the fixed rubber bumper softening the impact at the end of the insertion stroke.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X50 the Right Cylinder?
Choose this 20 mm bore when you need 132 N of equal both-way force; step down if lower thrust is acceptable, or step up to the 25 mm bore (206 N @0.5 MPa) for heavier resistance. Unlike the single-rod MBL, this MBLD provides dual-side guidance and anti-rotation, while the MBLCD variant offers adjustable air cushions instead of this model's fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. The plain design without a magnet means no sensor can be fitted. For exact replacement matching, verify the 20 mm bore, 50 mm stroke, G1/8 port, PT thread, and double-rod configuration.
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 MBLD20X50 FAQ
Because the rod exits both ends, the force is equal in both directions: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa.
No. This SKU lacks the -S built-in magnet, so it cannot trigger CMSG reed or DMSG/EMSG electronic sensors. You must use an external mechanical flag on the rear rod for position detection.
