Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X30S 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 MBLD20X30S
The AirTAC MBLD20X30S is a compact double-acting double-rod aluminum mini cylinder. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding equal 132 N force each way at 0.5 MPa. The 30 mm stroke is ideal for short indexing or ejection tasks in tight spaces.
This S-suffix SKU includes a built-in magnet for CMSG reed or DMSG/EMSG electronic sensor switches. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod provide durable service, while the fixed rubber bumper absorbs end-of-stroke impact. Overall length equals A plus twice the stroke, so you must leave rear-rod clearance for the protruding end.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30S |
|---|---|
| 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 MBLD20X30S Is Used
PCB Depanelling Ejector
Uses the 132 N equal both-way force to push singulated circuit boards out of a routing fixture, while the rear rod simultaneously trips a pneumatic blow-off valve.
Sensor Test Head Actuator
Drives a delicate probe 30 mm onto semiconductor chips, relying on the twin-rod anti-rotation property to keep the contact pad perfectly aligned.
Label Applicator Tamp
Tamps adhesive labels onto small vials; the lightweight 20 mm body fits between conveyor guides and the rear rod mounts a physical limit flag.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X30S the Right Cylinder?
For short 30 mm strokes, stepping down is not possible as 20 mm is the smallest bore. If you need more push, the 25 mm bore provides 206 N at 0.5 MPa. Unlike the single-rod MBL, this double-rod design gives equal extend/retract forces and allows a cam or position flag on the rear rod. If you need adjustable air cushions instead of the fixed rubber bumper, choose the MBLCD variant. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. A plain MBLD does not hold position without live air—the bumper softens impact but is not a lock. To replace this unit, match the 20 mm bore, 30 mm stroke, G1/8 port, PT thread, and -S 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 MBLD20X30S FAQ
Because a rod occupies both sides of the piston, extend and retract forces are equal. It outputs 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
A twin-rod configuration provides equal force and speed in both directions, and the protruding rear rod can drive a second mechanism or mount a position flag. The -S magnet on this unit also allows CMSG, DMSG, or EMSG switches to detect piston position.
