Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X15 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 15mm 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 MBLD20X15
The AirTAC MBLD20X15 is a compact double-acting double-rod aluminum mini cylinder with a 15 mm 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 very short, rapid positioning tasks where a single-rod cylinder would introduce a force differential.
The twin Ø8 mm hard-chrome carbon-steel rods provide inherent anti-rotation guidance and allow you to mount a cam or position flag on the rear rod end. This SKU has no built-in magnet, so it cannot support a CMSG or DMSG position sensor. End impact is absorbed by a fixed rubber bumper, while the riveted rolling-packed aluminum barrel keeps the overall footprint tight for cramped machinery.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 15 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 MBLD20X15 Is Used
PCB Edge Guiding
Uses the symmetric 132 N force and 15 mm stroke to center electronic circuit boards on a conveyor without rotational drift, thanks to the twin-rod guidance.
Sensor Cam Triggering
Mounts a mechanical cam on the rear protruding rod end to actuate external limit switches in a tightly packed semiconductor testing fixture.
Label Tamp Dispensing
Provides equal push and pull speed for a short 15 mm tamp stroke on a packaging line, ensuring labels are applied without skewing.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15 the Right Cylinder?
Choose this 20 mm bore when you need symmetric 132 N force in a 15 mm stroke; if you need less force, step down is not available as 20 mm is the smallest size, but if you need more force, step up to the 25 mm bore which provides 206 N at 0.5 MPa. For applications requiring adjustable air cushions at the stroke ends instead of the fixed rubber bumper found here, specify the MBLCD variant. Mounting is limited to Basic, FA flange, or LB foot brackets—MBLD does not offer a back-cover or SDB pivot option.
When ordering a replacement, confirm the 20 mm bore, 15 mm stroke, G1/8 port, and default PT thread. Because this specific SKU lacks the -S magnet code, it cannot accept an electronic or reed switch; if position feedback is required, select an MBLD20X15S unit. Note that the fixed rubber bumper softens end-of-stroke impact but does not lock the rod—unpressurized loads will drift.
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 MBLD20X15 FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It outputs 132 N at 0.5 MPa and 185 N at 0.7 MPa. The maximum theoretical force is 27 kgf at 1.0 MPa.
The twin rods provide equal extend/retract force and better anti-rotation support, with the rear rod available for mounting cams or flags. This specific MBLD20X15 SKU lacks a built-in magnet, so it cannot take a CMSG or DMSG sensor; you must use live air to control position as the bumper does not lock the rod.
