Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X200
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X200 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 200mm 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 MBLD25X200
The AirTAC MBLD25X200 is a double-acting, double-rod aluminum mini cylinder featuring a 25mm bore and 200mm stroke. Because a Ø10mm rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 206N of force each way at 0.5MPa. The 200mm stroke suits extended travel for pushing, pulling, or transferring parts across a machine bed.
This configuration uses a fixed rubber bumper at stroke ends to soften impact, while the riveted rolling-packed aluminum barrel keeps the body light for tight spaces. A carbon-steel rod with 20µm hard-chrome plating resists wear. This specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors. Overall length equals A plus twice the stroke, meaning the rear rod requires dedicated clearance space.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X200 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X200 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 200 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 MBLD25X200 Is Used
PCB Conveyor Gating
Drives a dual-sided gate arm on a PCB conveyor system, using the 206N equal force to reliably push and pull lightweight transfer pallets without rotational skew.
Textile Loom Tensioner
Acts as a tensioning cam in a textile loom, where the rear rod end mounts a position flag to mechanically trigger a lever while the front rod maintains consistent yarn tension.
Semiconductor Wafer Transfer
Pushes wafer cassettes across a 200mm gap in semiconductor handling equipment, leveraging the compact riveted aluminum body to fit within tight cleanroom process enclosures.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X200 the Right Cylinder?
When sizing this model, stepping down to the 20mm bore gives 132N both ways at 0.5MPa, while stepping up to the 32mm bore provides 346N. The double-rod design is ideal when you need equal push/pull force and anti-rotation guidance, but if your application requires adjustable air cushioning, choose the MBLCD variant instead. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for this type.
At 200mm of stroke, the Ø10mm rod is highly susceptible to side-load bending. Even with twin rods providing better rotational stability than a single rod, you must use an external guide rail to prevent binding and premature seal wear. This plain MBLD25X200 does not hold position without live air—the rod drifts if pressure drops, and the rubber bumper is not a lock. To replace it, match the 25mm bore, 200mm stroke, G1/8 port, PT thread, and Basic mounting.
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 MBLD25X200 FAQ
Because the double-rod design has a rod on both sides of the piston, the effective area is equal in both directions. The force is 206N at 0.5MPa and 289N at 0.7MPa both extending and retracting. The maximum theoretical force is 42kgf at 1.0MPa.
No, this specific MBLD25X200 SKU lacks the built-in magnet (denoted by an -S suffix), so it cannot host AirTAC CMSG reed or DMSG/EMSG electronic sensors. You would need the MBLD25X200S variant for solid-state or reed switch position detection.
