Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X200S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X200S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 200mm 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 MBLD50X200S
The AirTAC MBLD50X200S is a compact double-acting double-rod aluminum mini cylinder featuring a 50mm bore and 200mm stroke. A single piston drives a Ø16mm carbon-steel rod out of both end covers, yielding identical annulus areas. Consequently, it generates 881N of force at 0.5 MPa on both extend and retract strokes. The built-in magnet (-S) enables position detection via CMSG reed or DMSG/EMSG electronic switches. This 200mm travel suits mid-range indexing and transfer tasks.
Because a rod protrudes from the rear cover, you can mount a workpiece on one end and a cam or position flag on the other, achieving dual-side guidance and anti-rotation. The riveted rolling-packed aluminum barrel and grease-retaining piston seal ensure reliable service, while fixed rubber bumpers absorb end-of-travel impacts. Remember that overall length equals the body length plus twice the stroke, so plan rear-rod clearance accordingly.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X200S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 200 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 MBLD50X200S Is Used
PCB Stacking Alignment
Drives a dual-sided alignment blade in a PCB magazine loader. The twin rods prevent binding across the 200mm stroke, while the 881N equal both-way force ensures smooth stack separation and retraction.
Textile Web Diverting
Powers a reversing diverter bar on a textile winder. The rear rod end mounts a physical limit flag for a DMSG sensor, tracking the 200mm travel while the cylinder handles equal tension in both directions.
Semiconductor Wafer Pusher
Transfers wafer cassettes between process chambers. The 1233N force at 0.7 MPa provides positive push and pull, with the fixed rubber bumper protecting delicate silicon loads at stroke ends.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X200S the Right Cylinder?
When sizing this 50mm bore, consider stepping down to the 40mm bore (528N at 0.5 MPa) for lighter loads, or up to the 63mm bore (1457N at 0.5 MPa) for heavier thrust. If your application requires adjustable pneumatic cushioning rather than fixed rubber bumpers, choose the MBLCD variant. If a single rod suffices, the standard MBL cylinder offers a larger push-side force.
Mounting is limited to Basic, FA flange, or LB foot brackets; MBLD does not support back-cover or SDB pivot mounts. The -S code confirms the magnet is fitted for CMSG/DMSG/EMSG sensors. At a 200mm stroke, the Ø16mm rod still requires an external guide to prevent side-load bending. Note that a plain MBLD does not hold position without live air; the bumper softens impact but does not lock the rod. Replacement requires matching the 50mm bore, 200mm stroke, G1/4 port, PT thread, and 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 MBLD50X200S FAQ
Because the double-rod design creates equal annulus areas on both sides, the force is identical in both directions: 881N at 0.5 MPa, 1233N at 0.7 MPa, and a maximum theoretical 180kgf at 1.0 MPa.
The -S code means a magnet is built into the piston for electronic or reed sensing. You can mount CMSG (reed), DMSG, or EMSG (solid-state) switches along the barrel to detect position. Unlike a single-rod cylinder, the double rod provides equal extend and retract forces, and the rear protruding rod can drive a secondary cam or mechanism.
