Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X175S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 175mm 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 MBLD20X175S
The AirTAC MBLD20X175S is a double-acting, double-rod aluminum mini cylinder featuring a 20mm bore and 175mm stroke. Because an 8mm rod exits both end covers, the annulus area is identical on each side, yielding exactly 132 N of force at 0.5 MPa in both extend and retract directions. The built-in magnet (-S) supports CMSG reed and DMSG or EMSG electronic sensors for position detection.
This 175mm travel length suits extended reach tasks in tight spaces, but remember the overall length equals A + 2 x stroke, so you must leave rear-rod clearance for the protruding shaft. The riveted aluminum barrel and 20 um hard-chrome plated carbon-steel rod provide durable service, while the fixed rubber bumper absorbs end-of-stroke impact without locking the load.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 175 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 MBLD20X175S Is Used
PCB Edge Conveyor Routing
Drives a lightweight routing flag on the front rod while the rear rod extends to trip a limit switch, using the 132N equal force to push panels smoothly.
Pick-and-Place Z-Axis
Uses the 175mm stroke to lower a small vacuum gripper; the double-rod design keeps the tool guided against rotation during vertical descent.
Label Dispenser Tensioning
Applies constant 132N pull force to a label web roller, with the rear rod end available to mount a physical position flag for a DMSG sensor.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175S the Right Cylinder?
Step down to the 12mm bore if you need lighter actuation, or step up to the 25mm bore (206 N at 0.5 MPa) if your payload exceeds 132 N. Unlike the single-rod MBL, this double-rod design gives equal push and pull forces, and unlike the MBLCD, it uses a fixed rubber bumper rather than an adjustable air cushion. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. Replacement requires a 20mm bore, 175mm stroke, G1/8 PT thread, and the -S magnet. At 175mm of travel, the 8mm twin rods still need an external guide to prevent 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 MBLD20X175S FAQ
Because the rod exits both ends, force is equal in both directions: 132 N at 0.5 MPa and 185 N at 0.7 MPa. The maximum theoretical force is 27 kgf at 1.0 MPa.
A single-rod MBL has a larger push force than pull force, while the MBLD20X175S provides identical extend and retract forces. The rear rod can also drive a second mechanism or mount a cam, but you must leave clearance for it to protrude.
