About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X225S
The AirTAC MBLD50X225S is a double-acting, double-rod aluminum mini cylinder featuring a Ø16mm rod exiting both end covers. Because the rod occupies both sides of the piston, the annulus area is identical in each direction, yielding exactly 881N of push and pull force at 0.5MPa. This 225mm stroke is well suited for mid-range traversing or indexing tasks. The built-in -S magnet allows CMSG, DMSG, or EMSG sensor switches to track rod position.
A defining trait of this twin-rod architecture is the ability to mount a workpiece on the front rod and a position flag or cam on the rear protruding rod, providing dual-side guidance that resists rotational torque better than a single rod. The body utilizes a riveted rolling-packed aluminum barrel with a heterogeneous two-way grease-retaining piston seal. End-of-stroke energy is absorbed by a fixed rubber bumper, not an adjustable air cushion. Note that overall length equals A + 2x stroke, so you must leave physical clearance for the rear rod.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X225S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X225S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 225 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M14×1.5 |
| 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 500 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 (Ø50mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 MBLD50X225S Is Used
Textile Loom Let-Off
Drives a dual-side tensioning arm on a weaving loom, using the 881N equal both-way force to maintain consistent yarn tension during extend and retract cycles.
PCB Conveyor Gating
Uses the rear rod end to mount a position flag for a DMSG electronic sensor, actuating a 225mm routing gate in electronics assembly lines.
Packaging Flap Folder
Folds carton flaps simultaneously from both sides, leveraging the anti-rotation stability of the twin 16mm rods during high-speed packaging operations.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X225S the Right Cylinder?
If you need less force, stepping down to the 40mm bore yields 528N at 0.5MPa; stepping up to the 63mm bore provides 1457N at 0.5MPa. Choose the single-rod MBL if your application only requires a pulling action and you lack rear-rod clearance, or the MBLCD if you need adjustable air cushioning to soften heavier 1233N impacts at 0.7MPa. Mounting is limited to Basic, FA flange, or LB foot brackets, as the double-rod design physically omits the back-cover and SDB pivot options. To replace this cylinder, match the 50mm bore, 225mm stroke, G1/4 port, PT thread, FA/LB mounting, and the -S magnet. For a 225mm stroke, the 16mm rod is highly susceptible to side-load bending, so an external linear guide is mandatory to prevent premature seal failure.
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 MBLD50X225S FAQ
The MBLD50X225S provides equal force in both directions due to the double-rod design. It delivers 881N at 0.5MPa, 1233N at 0.7MPa, and a maximum theoretical 180kgf (1765N) at 1.0MPa. Push and pull forces are identical.
The S indicates a built-in magnet for position detection using CMSG reed or DMSG/EMSG electronic sensors. The double-rod design means a rod protrudes from both ends, allowing you to mount a cam or flag on the rear rod while driving a load on the front, providing equal force and speed both ways.
