Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 250mm 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 MBLD25X250S
The AirTAC MBLD25X250S is a double-acting, double-rod aluminum mini cylinder engineered for applications requiring symmetrical motion. Because a Ø10 mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields equal bidirectional force and speed, delivering 206 N each way at 0.5 MPa. The built-in magnet (-S) enables position detection using AirTAC CMSG reed or DMSG/EMSG electronic switches.
At a 250 mm stroke, the overall length grows by twice the stroke, so rear-rod clearance is critical for your layout. The riveted rolling-packed barrel and 20 µm hard-chrome plated carbon-steel rod provide durable service in compact spaces. Impact is absorbed by a fixed rubber bumper at both ends, while the twin rods offer inherent anti-rotation support for light external loads.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 250 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 MBLD25X250S Is Used
PCB Edge Conveyor Routing
Drives a dual-sided routing head on a PCB conveyor, using the 250 mm stroke to span board widths while the rear rod carries a cam for synchronized flap opening.
Textile Yarn Tensioning
Applies 206 N of equal force in both directions to maintain consistent yarn tension on a textile winder, using the twin rods to prevent guide rotation during fast reversals.
Semiconductor Shuttle Transfer
Moves a lightweight wafer shuttle between test stations, using the -S magnet to trigger DMSG electronic sensors at 250 mm endpoints without mechanical stops.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250S the Right Cylinder?
When sizing this 25 mm bore model, stepping down to the 20 mm bore reduces your equal both-way force to 132 N at 0.5 MPa, while stepping up to the 32 mm bore increases it to 346 N. Choose the MBLD double-rod design over the single-rod MBL when your mechanism requires equal push/pull force, a rear rod for a cam or position flag, or better resistance to torsional twist. For heavier end impacts, the MBLCD variant offers adjustable air cushions, whereas this base MBLD relies on fixed rubber bumpers.
Mounting is limited to Basic, FA flange, or LB foot brackets—there is no back-cover or SDB pivot option for the double-rod series. At 250 mm, the Ø10 mm twin rods are highly susceptible to side-load bending; an external guide rail is strongly recommended to prevent premature seal wear. To replace this unit, match the 25 mm bore, 250 mm stroke, G1/8 PT port, and the -S magnet. Note that a plain MBLD drifts without live air—the rubber bumper softens impact but does not lock position.
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 MBLD25X250S FAQ
Because the MBLD25X250S is a double-rod cylinder, the force is identical in both directions. It provides 206 N at 0.5 MPa and 289 N at 0.7 MPa on both extend and retract. The maximum theoretical force is 42 kgf at 1.0 MPa.
A single-rod cylinder has a larger push force than pull force due to the rod occupying one side. The MBLD25X250S has a rod exiting both ends, making the annulus area equal on both sides for identical push/pull force and speed. The rear rod can also be used to mount a position flag or drive a secondary mechanism.
