Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X15
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X15 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 15mm 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 MBLD25X15
The AirTAC MBLD25X15 is a double-acting, double-rod aluminum mini cylinder featuring a 25mm bore and 15mm stroke. Because a rod exits both ends, the annulus area is identical on each side, delivering exactly 206 N of force at 0.5 MPa in both extend and retract directions. The 15mm stroke is ideal for short clamping or ejection tasks where space is extremely tight.
This configuration uses a G1/8 port, a Ø10 mm carbon-steel rod with 20 um hard-chrome plating, and a fixed rubber bumper at each end. The riveted rolling-packed barrel retains grease via a heterogeneous two-way piston seal. A rear rod protrudes from the back cover, allowing you to mount a position flag or cam while the twin rods keep the load guided against rotation.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X15 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X15 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 15 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 MBLD25X15 Is Used
PCB Edge Connector Clamping
Uses the 206 N bidirectional force to hold delicate printed circuit boards during edge-connector soldering, relying on the 15mm stroke for rapid, short-throw engagement.
Label Dispenser Pinch Roll
Drives a dual-sided pinch mechanism for label web feeding, where the twin rods prevent rotational twist on the rubber rollers during high-speed retraction.
IC Tray Sorting Gate
Actuates a short 15mm diverter gate in semiconductor tray handling, using the rear protruding rod to mount a mechanical cam that triggers a downstream micro-switch.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X15 the Right Cylinder?
Choose this 25mm bore when you need 206 N of equal bidirectional force in a compact footprint. If your task requires less force, step down to the 20mm bore, which provides 132 N at 0.5 MPa; if you need more power, step up to the 32mm bore, which yields 346 N at 0.5 MPa. For applications needing precise end-deceleration, select the MBLCD variant, which features an adjustable air cushion instead of this model's fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; the MBLD type does not support SDB pivot or back-cover mounting. This specific SKU lacks the -S magnet option, meaning it cannot accept AirTAC CMSG, DMSG, or EMSG position sensors. The fixed rubber bumper softens end impact but does not lock the rod; the cylinder will drift without live air pressure, so use an external locking device if static holding is required.
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 MBLD25X15 FAQ
Because the MBLD25X15 is a double-rod cylinder, the force is identical in both directions: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa.
A double-rod cylinder has a rod exiting both ends, making the extend and retract areas equal for matched force and speed. The rear rod can also drive a second mechanism or position flag, but it requires rear clearance and cannot use a back-cover mount.
