Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X30 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 MBLD20X30
The AirTAC MBLD20X30 is a compact, double-acting double-rod mini cylinder with a 20mm bore and 30mm stroke. Because an 8mm rod exits both end covers, the annular piston area is identical on extend and retract, yielding equal force and speed both directions at 132N (0.5MPa). A 30mm stroke suits short indexing moves where you attach a workpiece to the front rod and a cam or position flag to the rear.
This SKU has no built-in magnet (-S omitted), meaning it cannot accept CMSG, DMSG or EMSG position sensors. The riveted aluminum barrel and 20um hard-chrome plated carbon-steel rod provide durable service in tight spaces. End-of-travel impact is handled by fixed rubber bumpers, while overall length equals A plus twice the stroke, requiring rear-rod clearance.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 30 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 MBLD20X30 Is Used
PCB Edge Guide Ejector
Drives a front-side ejector pin to push cut PCBs from a routing fixture, while the rear rod carries a cam to trigger a downstream proximity sensor simultaneously.
Small Component Sorter
Uses its equal 132N push/pull to shuttle a tiny transfer carriage between two pick-and-place heads without speed variation, keeping chip placement cycles balanced.
Label Applicator Flag
Strokes 30mm to advance a label wipe blade, while the protruding rear rod physically flips a mechanical diverter gate to route packaging flat blanks.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30 the Right Cylinder?
The 132N both-way output fits light-duty tasks. If you need less force, step down is not possible as 20mm is the smallest MBLD bore. If you need more power, step up to the 25mm bore, which provides 206N at 0.5MPa. For heavier impacts requiring adjustable air cushioning, use the MBLCD variant instead of this fixed-bumper model.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. This plain MBLD20X30 uses PT tapered port threads. It does not hold position without live air—the rod drifts and the bumper only softens impact, so use an external lock for holding. Replacement match: 20mm bore, 30mm stroke, G1/8 port, PT thread, no magnet.
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 MBLD20X30 FAQ
Because a rod exits both ends, the effective piston area is equal on extend and retract. Force is 132N both ways at 0.5MPa, 185N both ways at 0.7MPa, and a maximum of 27kgf at 1.0MPa. There is no larger push-side figure for this double-rod type.
No. This specific SKU lacks the -S code, meaning no magnet is built into the piston, so CMSG reed or DMSG/EMSG electronic switches cannot detect rod position. To use sensors, select the MBLD20X30S variant instead. The double-rod design still allows you to mount a physical flag on the rear rod for external mechanical tracking.
