Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X225S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X225S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 225mm 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 MBLD20X225S
The AirTAC MBLD20X225S is a compact double-acting double-rod aluminum mini cylinder featuring a 20 mm bore and 225 mm stroke. Because an Ø8 mm rod protrudes from 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) allows CMSG reed or DMSG/EMSG electronic sensors to track position, while the fixed rubber bumper absorbs end-of-stroke impact.
With a 225 mm stroke, the overall length grows by twice the stroke (A + 450 mm), so you must leave rear-rod clearance for the protruding tail. This tail can drive a secondary mechanism or mount a position flag. The riveted rolling-packed barrel and hard-chrome carbon-steel rod provide durable guidance, though at this length the small 8 mm rod still needs an external guide to prevent bending under side loads.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X225S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X225S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 225 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 MBLD20X225S Is Used
PCB Depaneling Router
Drives a cutting head on an electronics assembly line, using the equal 132 N extend and retract force to push and pull the blade through router slots without speed mismatch.
Label Dispenser Cam
Uses the rear protruding rod to actuate a mechanical cam on a packaging line, timing the label peel-off precisely while the front rod advances the web.
Connector Insertion Head
Pushes IC sockets into PCBs in semiconductor testing, relying on the twin rods to resist rotational twist and keep the 225 mm travel perfectly aligned.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X225S the Right Cylinder?
This 20 mm bore provides 132 N both ways at 0.5 MPa. If you need less force, a smaller option does not exist in this series, but stepping up to the 25 mm bore yields 206 N both ways. The fixed rubber bumper suits moderate cycling, but for higher kinetic energy at 225 mm stroke, consider the MBLCD variant which adds adjustable air cushions. Mounting is limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option. To replace this unit, match the 20 mm bore, 225 mm stroke, G1/8 PT port, 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 MBLD20X225S FAQ
Because a rod exits both ends, the force is identical in both directions. It generates 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 due to the rod displacing piston area. The MBLD double-rod design equalizes this annulus area, giving identical push and pull forces. It also provides a rear rod that can mount a position flag or drive a secondary mechanism.
