Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X50
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X50 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 50mm 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 MBLD25X50
The AirTAC MBLD25X50 is a double-acting, double-rod aluminum mini cylinder engineered for symmetrical motion control. Because a Ø10 mm piston rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 206 N of force both ways at 0.5 MPa. The 50 mm stroke is well-suited for compact indexing and short-transfer tasks. A fixed rubber bumper absorbs end-of-travel impact, while the riveted rolling-packed aluminum barrel keeps the body light for tight machine spaces.
This specific SKU omits the internal magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing. The rear rod protrudes equally with the front, allowing you to mount a position flag or cam on the opposite side to trigger external mechanical switches. With a PT tapered port thread and a 20 µm hard-chrome plating on the carbon-steel rod, it provides durable service in confined packaging and assembly zones.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X50 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X50 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 50 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 MBLD25X50 Is Used
PCB Depaneling Saw Feed
Drives a 50 mm stroke to push a circular saw blade into printed circuit boards, using the twin rod's equal 206 N force and anti-rotation stability to maintain a straight, chatter-free cut.
Semiconductor Wafer Gate
Actuates a 50 mm indexing gate inside a wafer transfer chamber, using the rear rod end to mount a mechanical cam that trips a physical limit switch without needing an internal magnet.
Label Applicator Press
Tamps labels onto small cartons with 206 N of equal force both directions, ensuring consistent adhesion without overshooting, while the compact 25 mm bore fits between narrow conveyor rails.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X50 the Right Cylinder?
When sizing this 25 mm bore, stepping down to the 20 mm bore reduces your equal both-way force to 132 N at 0.5 MPa, whereas stepping up to the 32 mm bore increases it to 346 N. Choose the MBLD over the single-rod MBL when your mechanism requires equal push/pull dynamics or a rear-rod cam. If your application demands adjustable end-cushioning to soften heavier impacts, select the MBLCD variant instead of this fixed-bumper base model.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for this double-rod configuration. Note that a plain MBLD does not hold position without live air pressure—the rod will drift. For an exact replacement, match the 25 mm bore, 50 mm stroke, G1/8 port, PT thread, and confirm no magnet 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 MBLD25X50 FAQ
Because the double-rod design has equal piston annulus area on both sides, the extend and retract 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 MBLD25X50 SKU lacks the built-in magnet (denoted by an 'S' in the ordering code), so it cannot accept CMSG reed or DMSG/EMSG electronic switches. However, you can mount a physical flag or cam on the protruding rear rod to trigger external sensors.
