Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X30
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X30 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 30mm 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 MBLD50X30
The AirTAC MBLD50X30 is a compact double-acting double-rod aluminum mini cylinder delivering 881 N of force in both extend and retract directions at 0.5 MPa. Because a Ø16 mm carbon-steel rod protrudes from both end covers, the annular piston area is identical on each side. This 30 mm stroke suits short indexing moves where equal push and pull power is mandatory. The riveted rolling-packed barrel and grease-retaining two-way piston seal keep the internal mechanics protected in tight machinery spaces.
This base configuration features a fixed rubber bumper to soften end-of-travel impacts and lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without a physical upgrade. The twin rods inherently resist torsional loads better than a single rod, allowing you to mount a workpiece on the front rod and a mechanical cam or position flag on the rear. Remember that the rear rod requires equal clearance to the front, as overall length scales with twice the stroke.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X30 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X30 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 30 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 MBLD50X30 Is Used
PCB Depaneling Saw Feed
Drives a short 30 mm stroke circular saw blade forward and back in a PCB depaneling router, utilizing the 881 N symmetric force to ensure the blade retracts from the cut with the same power as it plunges.
Textile Loom Tensioner Cam
Uses the rear protruding rod to actuate a mechanical tensioning cam on a weaving loom, synchronizing the 881 N clamping force on the front side with the rear mechanical timing without needing a separate actuator.
Connector Pin Insertion Head
Presses IDC connector pins into ribbon cable headers, relying on the twin 16 mm rods to prevent chassis rotation during the 30 mm high-speed insertion cycle while maintaining 881 N of thrust.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X30 the Right Cylinder?
When sizing this 50 mm bore, stepping down to the 40 mm bore drops the equal both-way force to 528 N at 0.5 MPa, whereas stepping up to the 63 mm bore increases it to 1457 N. Choose the MBLD50X30 if 881 N symmetric thrust fits your short 30 mm travel requirement. If your application suffers from severe end-impact shock, switch to the MBLCD variant, which replaces the fixed rubber bumper with an adjustable air cushion. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for the double-rod body. To replace this unit, match the 50 mm bore, 30 mm stroke, G1/4 port, PT thread, and no-magnet specification.
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 MBLD50X30 FAQ
The MBLD50X30 provides equal force in both directions due to the double-rod design. It outputs 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a maximum theoretical 180 kgf at 1.0 MPa. Because the rod occupies both sides of the piston, the push and pull forces are identical.
No, this specific MBLD50X30 SKU lacks the built-in magnet (denoted by an 'S' in the code) and cannot accept AirTAC CMSG reed or DMSG/EMSG electronic solid-state sensors. You would need to order the MBLD50X30S variant to enable piston-position detection.
