Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X25
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X25 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 25mm 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 MBLD25X25
The AirTAC MBLD25X25 is a double-acting, double-rod aluminum mini cylinder featuring a 25mm bore and 25mm stroke. Because a Ø10mm carbon-steel rod exits both end covers, the annulus area is identical on both sides, yielding exactly 206N of force at 0.5 MPa in both extend and retract directions. The riveted rolling-packed barrel and grease-retaining piston seal keep it compact and reliable in tight spaces.
This configuration uses a default PT tapered port thread and lacks the -S magnet suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor. A fixed rubber bumper absorbs end-of-stroke impact rather than using an adjustable air cushion. The rear rod protrudes simultaneously, allowing you to mount a cam or position flag on one end while driving the workpiece on the other.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X25 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X25 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 25 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 MBLD25X25 Is Used
PCB Pick-and-Place
Drives a 25mm vertical pickup head for electronic component placement, using the rear rod to trigger a reed flag for stroke confirmation.
Textile Web Guide
Shifts a light fabric guide bracket with equal 206N force both directions, preventing asymmetric tension drift during high-speed loom weaving.
Label Dispenser
Actuates a small labeling applicator arm in a packaging machine, relying on the twin rods to keep the pad perfectly parallel to the web.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X25 the Right Cylinder?
For 25mm bore sizing, stepping down to the MBLD20X25 yields 132N at 0.5 MPa, while stepping up to the MBLD32X25 provides 346N at 0.5 MPa. Choose this double-rod MBLD over the single-rod MBL when your mechanism requires equal push/pull forces or dual-side guidance to prevent load rotation. If your application needs adjustable end-cushioning to handle heavier moving masses, select the MBLCD variant instead.
Mounting is restricted to Basic, FA flange, or LB foot brackets; MBLD does not support back-cover or SDB pivot mounting. Remember that the fixed rubber bumper softens impact but does not lock the rod; a plain MBLD will drift without live air pressure, so use an external locking device for position holding. When replacing, match the 25mm bore, 25mm stroke, G1/8 port, PT thread, and non-magnet standard.
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 MBLD25X25 FAQ
Because the double-rod design has equal piston annulus area on both sides, the force is identical in both directions: 206N at 0.5 MPa, 289N at 0.7 MPa, and a maximum theoretical 42kgf at 1.0 MPa.
No, this specific SKU lacks the -S code, meaning no built-in magnet is fitted. You must select an MBLD25X25S variant to use CMSG reed or DMSG/EMSG electronic solid-state switches for rod position detection.
