Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X30S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X30S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 30mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 206 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X30S
The AirTAC MBLD25X30S is a double-acting, double-rod aluminum mini cylinder engineered for symmetrical motion. Because a Ø10 mm rod exits both ends, the annulus area is identical on extend and retract, yielding exactly 206 N of force each way at 0.5 MPa. The 30 mm stroke suits short indexing transfers and compact part ejection. This -S configuration includes a built-in magnet for CMSG reed or DMSG/EMSG solid-state position sensing.
Overall length equals A plus 2x stroke, meaning the rear rod protrudes and requires dedicated clearance. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome carbon-steel rod provide rigid, anti-rotation guidance. Impact at the extremes is absorbed by fixed rubber bumpers, which soften end-of-travel shock but do not lock the rod in place without constant air pressure.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X30S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X30S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 30 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 (Ø25mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 MBLD25X30S Is Used
PCB Shuttle Routing
Drives a 30 mm transfer shuttle on a PCB pick-and-place machine, using the twin rods to prevent binding during short, repetitive indexing cycles.
Label Applicator Flag
Mounts a position flag on the rear rod to trigger a DMSG solid-state sensor, confirming a 30 mm label wipe-on stroke in real-time.
Dual-Side Gripper Cam
Actuates a small cam on the rear rod to open a spring-loaded gripper while the front rod pushes a micro-component into a test fixture.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X30S the Right Cylinder?
Delivering 206 N both ways, this 25 mm bore fits light-duty positioning. Stepping down to the 20 mm bore drops the bidirectional force to 132 N at 0.5 MPa, whereas moving up to the 32 mm bore increases it to 346 N. If your application needs adjustable air cushioning instead of fixed rubber bumpers, choose the MBLCD variant. If a single output rod suffices, the standard MBL provides higher forward push force.
Mounting is limited to Basic, FA flange, or LB foot styles; the MBLD design precludes back-cover or SDB pivot brackets. To replace this unit, match the 25 mm bore, 30 mm stroke, G1/8 port, default PT thread, and the -S magnet requirement. The cylinder does not hold position unpowered; fit an external locking device for vertical 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 MBLD25X30S FAQ
The double-rod design provides equal force in both directions: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum theoretical 42 kgf at 1.0 MPa.
The -S code indicates a built-in piston magnet, allowing external CMSG reed switches or DMSG/EMSG electronic sensors to detect the 30 mm stroke position. Without -S, the cylinder cannot accept any position sensor.
