Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X200
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X200 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 200mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X200
The AirTAC MBLD20X200 is a compact double-acting double-rod mini cylinder featuring a 20mm bore and 200mm stroke. A single piston drives an Ø8mm carbon-steel rod out of both end covers, yielding exactly 132N of force in both extend and retract directions at 0.5 MPa. This equal annulus area on both sides makes it ideal for operations requiring symmetrical push-pull dynamics. The 200mm stroke suits mid-range traversing tasks in tight machinery.
This SKU has a default PT (tapered) port thread and uses a G1/8 port. It lacks the -S magnet option, meaning it cannot support CMSG, DMSG, or EMSG position sensors. Because a rod protrudes from the rear, the overall length equals the body length plus twice the stroke, requiring rear clearance. The riveted aluminum barrel and fixed rubber bumper absorb end-of-travel impacts, though the bumper is not a locking device.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X200 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 200 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 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 (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 MBLD20X200 Is Used
PCB Edge Conveyor Routing
Drives a lightweight routing gate on a PCB conveyor using the 132N both-way force to ensure smooth, equal-speed actuation without asymmetric drift.
Tester Contact Cam
Uses the rear rod end to push a mechanical cam on an ICT tester fixture, timing a secondary probe engagement exactly with the main 200mm stroke.
Label Dispenser Flag
Mounts a physical position flag on the opposing rod end of a label applicator to mechanically trigger a micro-switch without needing an onboard sensor.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X200 the Right Cylinder?
If your application requires less force, stepping down is not possible as 20mm is the smallest available MBLD bore. Stepping up to the 25mm bore provides 206N at 0.5 MPa, offering a higher load margin if needed. Choose the MBLD over the single-rod MBL when you need a rear rod for mounting a position flag or secondary cam. If high kinetic energy at the 200mm stroke causes impact issues, consider the MBLCD variant which features an adjustable air cushion instead of the fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot brackets; no SDB pivot or back-cover options exist. To replace this cylinder, match the 20mm bore, 200mm stroke, G1/8 port, PT thread, and lack of magnet. Note that at 200mm stroke, the small 8mm rod is susceptible to bending under off-center loads; always use an external guide to prevent side-load damage.
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 MBLD20X200 FAQ
Because a rod occupies both sides of the piston, the effective annulus area is identical in both directions. The MBLD20X200 delivers 132N at 0.5 MPa and 185N at 0.7 MPa for both push and pull. The maximum theoretical force is 27kgf at 1.0 MPa. Extend and retract forces are perfectly equal.
No, this specific MBLD20X200 SKU does not include the -S code for a built-in magnet, so it cannot support CMSG, DMSG, or EMSG electronic or reed switches. If you need position detection, you must use an external mechanical flag on the rear rod or select an MBLD20X200S variant. The double-rod design still provides excellent anti-rotation guidance.
