Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X60
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X60 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 60mm 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 MBLD20X60
The AirTAC MBLD20X60 is a compact double-acting double-rod aluminum mini cylinder featuring a 20mm bore and 60mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 132 N of force each way at 0.5 MPa. This symmetric output is ideal for 60mm strokes requiring precise dual-side guidance without rotational drift.
It features a fixed rubber bumper to soften end-of-stroke impacts and a riveted rolling-packed aluminum barrel for tight spaces. The Ø8mm hard-chrome carbon-steel rod provides twin anchor points: mount a workpiece on the front and a position flag or cam on the rear. Note that overall length equals A + 2 x stroke, so you must leave clearance for the rear protrusion. This specific SKU uses default PT port threading and lacks a built-in magnet, meaning it cannot support CMSG or DMSG position sensors.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X60 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X60 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 60 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 MBLD20X60 Is Used
PCB Pick-and-Place
Drives a 60mm vertical pick-and-place head for electronic PCB assembly, using the twin rods to keep the vacuum gripper perfectly aligned against twist during high-speed retraction.
Label Dispenser Cam
Advances a label feed mechanism on the front rod while the rear rod physically trips a mechanical limit switch cam, ensuring synchronized mechanical feedback without electronics.
Connector Testing Jig
Applies exactly 132 N of clamping pressure to seat wire harness connectors in an automotive testing jig, ensuring the test head retracts with identical force to prevent component damage.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X60 the Right Cylinder?
Choose this 20mm bore when an application demands exactly 132 N of bidirectional force and 60mm of travel. If you need less push, step down to the 12mm bore class; for heavier loads, step up to the 25mm bore, which provides 206 N at 0.5 MPa. Unlike the single-rod MBL, this MBLD guarantees equal speed and force both ways. If end impacts are too harsh, consider the MBLCD variant, which offers adjustable air cushions instead of this model's fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot styles; MBLD does not support SDB pivot brackets or back-cover configurations. The plain rubber bumper is not a locking device, so the rod will drift if air pressure drops. For exact replacements, match the 20mm bore, 60mm stroke, G1/8 port, PT thread, and confirm no magnet is required. With a 60mm stroke on an 8mm rod, external guidance is still recommended to prevent rod bending under side loads.
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 MBLD20X60 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.
No. This specific SKU lacks the built-in magnet (denoted by an 'S' in the model code). Without the magnet, AirTAC CMSG reed and DMSG electronic sensors cannot detect piston position.
