Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X20 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 20mm 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 MBLD20X20
The AirTAC MBLD20X20 is a compact, double-acting double-rod mini cylinder featuring a 20 mm bore and a 20 mm stroke. Because a rod exits both end covers, the annulus piston area is identical on extend and retract, yielding exactly 132 N of force in both directions at 0.5 MPa. This symmetry is perfect for short 20 mm indexing or clamping tasks where the drive must behave identically whether pushing or pulling.
The riveted aluminum barrel keeps the frame light for tight spaces, while the Ø8 mm carbon-steel rod is plated with 20 µm hard chrome to resist wear. A fixed rubber bumper absorbs end-of-stroke impact, but note this SKU lacks the -S magnet option, so it cannot accept CMSG or DMSG position sensors. Overall length equals A plus twice the stroke, meaning the rear rod also protrudes and requires design clearance.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 20 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 MBLD20X20 Is Used
PCB Depaneling Saw
Drives a lightweight separator blade 20 mm to cut small printed circuit boards, utilizing the equal 132 N force to ensure smooth entry and exit without binding the fragile substrate.
Chip Test Handler
Pushes a test socket lid closed and pulls it open with identical 132 N force, ensuring consistent contact pressure on semiconductor packages during high-speed automated testing.
Label Applicator Tamp
Tamps a label onto small electronic components with a 20 mm stroke, using the rear protruding rod to mechanically trigger a pneumatic valve flag for cycle confirmation.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20 the Right Cylinder?
Stepping down is not possible as 20 mm is the smallest MBLD bore. If you need more power, the next size up is the 25 mm bore, which raises the bidirectional force to 206 N at 0.5 MPa. For applications needing adjustable air cushioning instead of a fixed rubber bumper, consider the MBLCD variant. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option. When replacing this unit, match the 20 mm bore, 20 mm stroke, G1/8 port, PT thread, and confirm no magnet is fitted. The cylinder does not hold position without live air; the rod will drift if pressure drops.
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 MBLD20X20 FAQ
The MBLD20X20 provides equal force in both directions because the rod occupies both piston sides. It delivers 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
A double-rod cylinder has a rod exiting both ends, creating equal annulus areas so extend and retract forces and speeds are identical. The rear rod can also mount a cam or position flag. This specific MBLD20X20 SKU lacks a built-in magnet, so it cannot use reed or electronic sensors.
