Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X75
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X75 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 75mm 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 MBLD25X75
The AirTAC MBLD25X75 is a compact double-acting double-rod aluminum mini cylinder engineered for symmetrical motion. 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 75mm stroke is well suited for mid-travel pick-and-place or indexing tasks.
This configuration uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion (which requires the MBLCD variant). The riveted rolling-packed aluminum barrel houses a grease-retaining piston seal and a 20um hard-chrome plated carbon-steel rod. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X75 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X75 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 75 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 MBLD25X75 Is Used
PCB Depaneling Saw
Drives a circular blade forward and back through 75mm of travel, using the equal 206N force to ensure a consistent cutting feed rate regardless of direction.
Gripper Sync Mechanism
Uses the rear protruding rod end to mount a mechanical sync flag, ensuring the front 25mm bore jaws open and close simultaneously without rotational drift.
Connector Insertion Jig
Presses rectangular electronic connectors into sockets with 289N at 0.7MPa, relying on the fixed rubber bumper to absorb the sudden impact upon full insertion.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X75 the Right Cylinder?
If you need less output, the adjacent MBLD20X75 provides 132N at 0.5MPa; stepping up to the MBLD32X75 yields 346N. The twin rods help resist torsional loads, but for a 75mm stroke you should still use an external guide to prevent rod bending on offset loads. Mounting is restricted to Basic, FA flange, or LB foot brackets—MBLD does not support SDB pivot or back-cover configurations. When ordering a replacement, confirm the 25mm bore, 75mm stroke, G1/8 port, default PT thread, and no magnet. Since it lacks a magnet, external limit switches must be used for position detection.
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 MBLD25X75 FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 206N at 0.5MPa and 289N at 0.7MPa. The maximum theoretical force is 42kgf at 1.0MPa. There is no larger push-side figure because the rod occupies both sides of the piston.
A single-rod MBL has unequal extend and retract forces due to the rod displacing piston area on one side. The MBLD25X75 has a rod exiting both ends, equalizing force and speed while allowing you to mount a secondary cam or tool on the rear rod. This SKU lacks the -S magnet, so it cannot use reed or electronic sensors.
