Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250 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 MBLD25X250
The AirTAC MBLD25X250 is a double-acting, double-rod mini cylinder engineered for compact setups requiring symmetrical motion. Because a Ø10 mm rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 206 N of force each way at 0.5 MPa. A 250 mm stroke suits extended reach pick-and-place or long-transfer tasks without swapping to a larger body.
This SKU lacks the -S code, meaning no built-in magnet is fitted and it cannot host a CMSG reed or DMSG electronic sensor. The riveted aluminum barrel keeps weight low, while the fixed rubber bumper absorbs end-of-stroke impact. Remember that overall length equals the body plus 2 x stroke, so you must leave physical clearance at the rear for the protruding rod.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250 |
|---|---|
| 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 MBLD25X250 Is Used
PCB Edge Conveyor Transfer
Drives an extended 250 mm transfer arm in electronics assembly, using the twin-rod design to keep the board carrier guided and prevent yaw during long lateral shifts.
Dual-Tool Stamper
Mounts a marking stamp on the front rod and a position flag on the rear rod, allowing a mechanical limit switch to track the 206 N cycle without an internal sensor.
Component Ejector Pusher
Ejects molded plastic parts from a 250 mm deep die cavity, leveraging equal extend and retract force to positively pull the extraction tooling back out of the mold.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X250 the Right Cylinder?
Choose this 25 mm bore when you need 206 N of bidirectional thrust over a 250 mm travel. If your payload is lighter, step down to the 20 mm bore providing 132 N; if pushing heavier jigs, step up to the 32 mm bore yielding 346 N. For applications needing precise end-deceleration, select the MBLCD variant which features adjustable air cushions instead of this model's fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot—there is no SDB pivot or back-cover option. At 250 mm, the stroke approaches the 300 mm max for this bore; with a 10 mm rod, external guidance is mandatory to prevent rod bending under side loads. This non-magnetic SKU cannot hold position without live air and will drift if pressure drops; fit an external locking device for static holding. Replacement requires matching the 25 mm bore, 250 mm stroke, G1/8 port, and default PT thread.
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 MBLD25X250 FAQ
Because the double-rod design has equal piston areas on both sides, push and pull forces are identical: 206 N at 0.5 MPa, 289 N at 0.7 MPa, and a maximum theoretical 42 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet (no -S suffix), so CMSG reed or DMSG electronic switches cannot detect piston position. You must use an external mechanical flag on the rear rod for limit sensing.
