Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X80
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X80 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 80mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X80
The AirTAC MBLD50X80 is a double-acting, double-rod aluminum mini cylinder featuring an 80 mm stroke and a Ø16 mm carbon-steel rod exiting both end covers. Because a rod occupies both sides of the piston, the annulus areas match, yielding exactly 881 N of force at 0.5 MPa on both extend and retract strokes. The riveted rolling-packed barrel and grease-retaining two-way piston seal keep operations stable in tight spaces.
This configuration uses a fixed rubber bumper to soften end-of-travel impacts rather than an adjustable air cushion. Since this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors. The rear protruding rod is ideal for mounting a secondary cam or position flag, though overall length requires rear clearance.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X80 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X80 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 80 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 MBLD50X80 Is Used
PCB Conveyor Gate
Drives an 80 mm lift gate on a printed circuit board conveyor, using the twin rods to keep the platform guided against rotation without external rails.
Textile Tensioner
Applies 881 N of equal tension in both directions on a fabric guide frame, ensuring consistent material feed without force imbalance.
Chip Ejector Cam
Uses the rear protruding rod end to trigger a limit switch cam, sequencing a semiconductor chip ejection mechanism at 0.5 MPa.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X80 the Right Cylinder?
When sizing this 50 mm bore, stepping down to the 40 mm version drops your bidirectional force to 528 N at 0.5 MPa, while stepping up to the 63 mm bore increases it to 1457 N. Choose the MBLD50X80 when your application demands equal push and pull forces around 881 N with an 80 mm travel. If your mechanism experiences severe end-impact loads and needs adjustable cushioning rather than fixed rubber bumpers, select the MBLCD variant. For single-direction tasks where pull force can be lower, the single-rod MBL series is more compact.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. This plain PT-threaded model (G1/4 port) cannot hold position without live air—the rod drifts without an external locking device. Replacement parts must match the 50 mm bore, 80 mm stroke, PT thread, and lack of 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 MBLD50X80 FAQ
Because the MBLD50X80 is a double-rod cylinder, the push and pull forces are identical. It outputs 881 N at 0.5 MPa and 1233 N at 0.7 MPa, with a maximum theoretical force of 180 kgf at 1.0 MPa.
No. This specific SKU lacks the -S code, meaning no magnet is fitted and it cannot accept CMSG, DMSG, or EMSG switches. You would need the MBLD50X80S variant for electronic position sensing.
