Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X25 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 25mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25
The AirTAC MBLD20X25 is a compact double-acting double-rod aluminum mini cylinder with a 20 mm bore and 25 mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding equal force and speed both ways at 132 N at 0.5 MPa. The riveted rolling-packed aluminum barrel and 20 um hard-chrome plated carbon-steel rod keep the body light for tight spaces.
This configuration uses a fixed rubber bumper to soften end-of-stroke impact and lacks a built-in magnet, meaning no position sensor is fitted. You can mount a workpiece on one rod end and a position flag or cam on the rear protruding rod. Overall length equals A plus two times the stroke, so you must leave rear clearance.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 MBLD20X25 Is Used
PCB Depaneling Saw
Drives a lightweight blade carriage on a 25 mm stroke; the twin Ø8 mm rods keep the saw guided against rotational twist during repeated cuts.
Pick-and-Place Head
Uses 132 N of equal both-way force to extend and retract a small vacuum gripper, mounting the gripper on the front rod and a reed flag on the rear.
Label Dispenser
Peels labels on a short 25 mm stroke; the double-rod design ensures the wiper plate retracts at the exact same speed as it extends.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25 the Right Cylinder?
For higher force, step up to the 25 mm bore providing 206 N at 0.5 MPa; as the smallest available size, stepping down is not an option. Choose the single-rod MBL if you only need one working side and prefer a larger push force, or the MBLCD if your cycle requires adjustable air cushioning instead of the fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot brackets—no back-cover or SDB pivot options exist. To match this replacement, verify the 20 mm bore, 25 mm stroke, G1/8 port, PT thread, and lack of a magnet.
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 MBLD20X25 FAQ
The double-rod design provides equal force both ways: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa.
No. This MBLD20X25 SKU lacks the -S code for a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG switches. The double-rod design still allows you to mount an external flag on the rear rod for detection.
