Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 50mm 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 MBLD50X50S
The AirTAC MBLD50X50S is a double-acting, double-rod aluminum mini cylinder engineered to deliver equal force in both directions, outputting 881 N at 0.5 MPa and 1233 N at 0.7 MPa. Because a Ø16 mm carbon-steel rod protrudes from both end covers, the annular piston area is identical on extend and retract. This 50 mm stroke suits short-stroke clamping, indexing, and dual-side ejection tasks. The built-in magnet (-S) enables position detection.
A defining advantage of this through-rod layout is the ability to mount a workpiece on the front rod end and a position flag or cam on the rear rod end simultaneously. The riveted rolling-packed aluminum barrel houses a heterogeneous two-way grease-retaining piston seal, while end-of-travel impact is managed by a fixed rubber bumper. Note that overall length equals the base body length plus twice the stroke, requiring rear clearance for the protruding rod.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 50 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 MBLD50X50S Is Used
Injection Mold Ejection
Drives a stripper plate in a 50-ton injection molding machine, using the 881 N both-way force to positively eject parts on the forward stroke and retract the plate smoothly without rotation.
Printed Circuit Board Transfer
Synchronizes a dual-side pick-and-place handler in PCB assembly, mounting a suction cup on the front rod and a physical position flag on the rear rod to trigger a downstream reed CMSG sensor.
Textile Web Guiding
Actuates a pivoting fabric guide roller in a textile winding machine, relying on the twin-rod's inherent anti-rotation properties to maintain web edge alignment under dynamic load.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X50S the Right Cylinder?
When sizing this 50 mm bore, stepping down to the 40 mm bore drops the both-way force to 528 N at 0.5 MPa, whereas stepping up to the 63 mm bore raises it to 1457 N at 0.5 MPa. Choose the MBLD over the single-rod MBL when equal push/pull speeds and dual-side guidance are required to prevent load rotation. If high kinetic energy at stroke ends threatens the fixed rubber bumper, consider the MBLCD variant which features adjustable air cushioning.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for the double-rod series. The base PT port thread matches standard pneumatic fittings. Remember that a plain cylinder drifts without live air—the rubber bumper softens impact but does not lock position. For replacements, verify the 50 mm bore, 50 mm stroke, G1/4 port, PT thread, and the -S 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 MBLD50X50S FAQ
The double-rod design provides identical push and pull force because the piston sees the same annulus area in both directions. The output is 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a maximum theoretical 180 kgf at 1.0 MPa.
The -S code indicates a built-in magnet for use with AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches to track rod position. The double-rod layout means a rod exits both ends, allowing you to mount a workpiece on the front and a sensor target or cam on the rear, while providing equal force and speed both ways.
