Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X25S 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 MBLD20X25S
The AirTAC MBLD20X25S is a compact double-acting double-rod aluminum mini cylinder featuring a 20mm bore and 25mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 132 N of force each way at 0.5 MPa. The built-in magnet (-S) allows a CMSG reed or DMSG/EMSG electronic sensor to track piston position. This short 25mm stroke is ideal for tight-pitch gripping. The twin Ø8mm hard-chrome rods provide inherent anti-rotation guidance, while the fixed rubber bumper absorbs end-of-stroke impact without acting as a position lock. Overall length equals A + 2 x stroke, so you must leave rear-rod clearance for the protruding shaft to avoid collision. Mounting is limited to Basic, FA flange, or LB foot brackets; no back-cover or SDB pivot option exists for this type.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25S |
|---|---|
| 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 MBLD20X25S Is Used
PCB Edge Clamping
Uses the 132N equal force to grip delicate printed circuit boards during routing, with the rear rod driving a synchronized secondary stopper flag.
Sensor Flag Actuation
The protruding rear rod mounts a cam that triggers an external proximity switch, confirming the 25mm stroke completed without rotating the load.
Label Applicator Pin
Twin Ø8mm rods prevent yaw during the rapid 25mm extension to tamp labels onto small pharmaceutical vials precisely.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X25S the Right Cylinder?
At 132 N both ways, this 20mm bore suits light pick-and-place. Stepping up to the 25mm bore yields 206 N at 0.5 MPa, while stepping down is not an option as 20mm is the smallest MBLD size. If your cycle creates heavy end-impacts, switch to the MBLCD variant which offers adjustable air cushions instead of this fixed rubber bumper. Note that a plain MBLD drifts without live air; use an external locking device if you need strict position holding. For replacements, confirm the 20mm bore, 25mm stroke, G1/8 port, PT thread, FA/LB mounting, and the -S 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 MBLD20X25S FAQ
Because the rod occupies both sides of the piston, push and pull forces are equal: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
The -S code means a built-in magnet for AirTAC CMSG (reed) or DMSG/EMSG (electronic) switches. The double-rod layout means a rod protrudes from the rear cover, allowing you to mount a secondary cam or tool there while gaining better anti-rotation resistance than a single-rod cylinder.
