Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X80
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X80 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 80mm 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 MBLD25X80
The AirTAC MBLD25X80 is a double-acting, double-rod mini cylinder featuring a 25mm bore and 80mm stroke. Because a Ø10mm rod exits both end covers, the annular piston area is identical on extend and retract. This yields equal push and pull forces of 206N at 0.5MPa and 289N at 0.7MPa, making it ideal for 80mm strokes requiring symmetrical dynamics. The riveted aluminum barrel keeps the frame compact for tight machine layouts.
This PT-threaded model uses G1/8 ports and relies on a fixed rubber bumper to soften end-of-stroke impacts. A key advantage of the through-rod design is dual-side guidance: you can mount a workpiece on the front rod and a position flag or cam on the rear rod, which helps resist torsional loads better than a single rod. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors. Overall length equals the base body length plus twice the stroke, so you must leave rear-rod clearance in your layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X80 Technical Specifications

|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 80 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 MBLD25X80 Is Used
PCB Edge-Belt Nudging
Drives an 80mm stroke nudger arm on a PCB conveyor to align boards, using the 206N both-way force to push and pull components without speed mismatch.
Textile Web Guide Flag
Mounts a guide roller on the front rod and a mechanical limit flag on the rear protruding rod, utilizing the twin-rod anti-rotation benefit for textile web tracking.
Pick-and-Place Ejection
Actuates an 80mm ejection stroke in a small pick-and-place unit, where the fixed rubber bumper absorbs the repetitive end impacts at operating speeds up to 800mm/s.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X80 the Right Cylinder?
If your mechanism needs less force, the neighboring 20mm bore provides 132N at 0.5MPa, whereas stepping up to the 32mm bore yields 346N at 0.5MPa. Choose this double-rod MBLD over the single-rod MBL when your application strictly demands equal extend and retract speeds or a rear-rod flag. If your load requires adjustable air cushioning rather than fixed rubber bumpers, select the MBLCD variant instead. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. Since this SKU lacks the -S magnet code, it cannot support electronic position sensing. To replace this cylinder, match the 25mm bore, 80mm stroke, PT thread, and double-rod configuration.
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 MBLD25X80 FAQ
Because the double-rod design has a rod on both sides of the piston, the effective area is equal in both directions. The push and pull forces are identical: 206N at 0.5MPa, 289N at 0.7MPa, and a maximum theoretical 42kgf at 1.0MPa.
A single-rod cylinder has unequal extend and retract forces due to the rod displacing volume on one side. The MBLD25X80 has a rod exiting both ends, providing equal force and speed both ways, plus a rear rod for mounting a cam or flag. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
