Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X20S 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 MBLD20X20S
The AirTAC MBLD20X20S is a double-acting, double-rod aluminum mini cylinder featuring a 20mm bore and 20mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 132 N of force each way at 0.5 MPa. The built-in magnet (-S) lets you track position with CMSG reed or DMSG/EMSG solid-state switches.
This compact riveted-barrel design suits tight spaces where a single rod would twist under load. You can mount a workpiece on the front rod and a position flag or cam on the rear. Overall length equals A plus twice the stroke, so you must leave rear-rod clearance. The 20um hard-chrome carbon-steel rod and grease-retaining piston seal ensure smooth service within the -20 to +70 C range.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20S |
|---|---|
| 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 MBLD20X20S Is Used
PCB Edge-Guide Finger
Uses the 132N equal both-way force to gently guide and square printed circuit boards on a conveyor without rotating the delicate panel.
Chip-Sort Diverter Arm
Drives a small flipper gate on a semiconductor chip handler, using the rear rod end to mount a physical position flag for a DMSG sensor.
Label Dispenser Tensioner
Maintains precise bidirectional tension on a narrow web labeling machine, leveraging the twin-rod anti-rotation property over the 20mm stroke.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X20S the Right Cylinder?
At 132 N both ways, stepping up to the 25mm bore gives 206 N at 0.5 MPa if your payload is heavier, while dropping below 20mm is not available in this series. The fixed rubber bumper absorbs end-of-stroke impact; if your cycle rate is high and you need adjustable air cushioning, choose the MBLCD double-rod variant instead. 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; add an external lock for fail-safe holding. To replace this unit, match the 20mm bore, 20mm stroke, G1/8 port, M8x1.25 rod thread, PT thread form, and the -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 MBLD20X20S FAQ
Because the double-rod design has equal piston area on both sides, push and pull forces are identical: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
A single-rod MBL has higher push force than pull force, while the MBLD20X20S has exactly equal force and speed in both directions. The MBLD also provides a rear rod end for mounting a cam or position flag, and offers better resistance to rod twisting, though it requires rear-rod clearance.
