Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X15S 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 MBLD20X15S
The AirTAC MBLD20X15S is a double-acting, double-rod aluminum mini cylinder featuring a 20mm bore and 15mm stroke. Because a carbon-steel rod with 20µm hard-chrome plating protrudes from both end covers, the annulus piston area is identical on extend and retract. This yields exactly 132N of force at 0.5 MPa in both directions, preventing the speed and force asymmetry found in single-rod designs. The built-in magnet (-S) allows position detection via CMSG reed or DMSG/EMSG electronic switches.
This 15mm stroke variant is purpose-built for extremely tight spaces where a standard 10mm stroke lacks reach and a 25mm stroke would bottom out. It uses a riveted rolling-packed aluminum barrel and a fixed rubber bumper to soften end-of-travel impact. The twin rods provide inherent anti-rotation resistance, allowing you to mount a workpiece on the front rod and a mechanical cam or position flag on the rear rod, which requires its own clearance space equal to the stroke length.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15S |
|---|---|
| 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 MBLD20X15S Is Used
PCB Edge Guiding
Drives a dual-sided guide arm on a pick-and-place machine, using the equal 132N both-way force to gently align circuit boards without rotational skew during transit.
Sensor Flag Actuation
Cycles a 15mm stroke to push a small test probe in an electronics tester, while the rear rod protrudes to trigger an external DMSG electronic limit switch.
Micro-Clamp Release
Opens and closes a small pneumatic clamp in a semiconductor wafer handler, where the short 15mm stroke and compact 20mm body fit within a dense tooling array.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X15S the Right Cylinder?
If your mechanism needs less push, the MBLD20X10S offers identical 132N force with 5mm less travel. For higher force, stepping up to the MBLD25 bore provides 206N at 0.5 MPa. Keep in mind MBLD mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. The fixed rubber bumper softens impact but does not lock the rod—unpowered position holding requires an external guide or lock. To replace this unit, match the 20mm bore, 15mm stroke, G1/8 PT port thread, and the -S magnet configuration.
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 MBLD20X15S FAQ
The double-rod design means extend and retract forces are equal because the rod occupies both piston sides. It generates 132N at 0.5 MPa, 185N at 0.7 MPa, and a maximum of 27kgf at 1.0 MPa in both directions.
The -S code indicates a built-in magnet for CMSG reed or DMSG/EMSG electronic sensors to detect position. The double-rod layout provides twin-rod anti-rotation stability and allows you to mount a secondary cam or position flag on the rear rod, which requires clearance for the 15mm stroke.
