Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X125S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X125S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 125mm 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 MBLD25X125S
The AirTAC MBLD25X125S is a double-acting, double-rod aluminum mini cylinder featuring a 25mm bore and 125mm stroke. Because a Ø10mm carbon-steel rod protrudes from both end covers, the annulus area is identical on both sides. This yields exactly 206N of force at 0.5MPa in both extend and retract directions, ensuring perfectly balanced, equal-speed motion. The built-in magnet (-S) enables position detection via CMSG reed or DMSG/EMSG electronic switches.
This 125mm stroke suits mechanisms requiring a long reach in a compact riveted barrel footprint. The twin-rod architecture provides inherent anti-rotation properties, keeping light loads guided far better than a single rod. End impact is absorbed by a fixed rubber bumper. Note that overall length equals the base body plus twice the stroke, so you must leave rear-rod clearance for the protruding plunger.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X125S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X125S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 125 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 MBLD25X125S Is Used
Textile Loom Guide
Drives a 125mm yarn guide bar with equal 206N force both directions, preventing lopsided tension while the rear rod mounts a physical trip-flag for the loom controller.
PCB Conveyor Diverter
Uses the twin-rod body to push PCB panels smoothly across a 125mm transfer gap, resisting twist on the long stroke without needing an external linear guide.
Filament Spool Tensioner
Applies constant 206N pull and push to a winding arm, using the double-rod symmetry to maintain uniform tension on the spool regardless of extend or retract state.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X125S the Right Cylinder?
If your mechanism needs less travel, the neighbouring MBLD20X125S drops the output to 132N at 0.5MPa while shrinking the rod to Ø8mm. Stepping up to the MBLD32X125S increases force to 346N at 0.5MPa and upgrades the port to G1/8 with a Ø12mm rod.
Unlike the single-rod MBL, this design gives matching push/pull forces and a rear rod for mounting a cam or position flag. If your application suffers hard end-loads, the MBLCD variant offers adjustable air cushions instead of this fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. The PT thread is standard. Remember that the bumper softens impact but does not lock the rod; without live air, the cylinder drifts and cannot hold 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 MBLD25X125S FAQ
Because the double-rod design has equal annulus areas on both sides, the force is identical in both directions: 206N at 0.5MPa, 289N at 0.7MPa, and a maximum of 42kgf at 1.0MPa.
The -S code means a built-in magnet is fitted for non-contact position detection. It works with AirTAC CMSG reed switches as well as DMSG and EMSG electronic solid-state sensors. Without the -S code, the cylinder cannot accept a sensor.
