Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X10S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X10S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 10mm 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 MBLD20X10S
The AirTAC MBLD20X10S is a compact, double-acting double-rod aluminum mini cylinder. Because a rod protrudes from both end covers, the annulus area is identical on both sides, yielding equal push and pull force of 132 N at 0.5 MPa. This 10 mm stroke suits very short indexing moves where symmetrical displacement is critical. The built-in magnet (-S) enables position detection via AirTAC CMSG reed or DMSG/EMSG electronic switches.
A defining benefit of the twin-rod layout is dual-side guidance: you mount the workpiece on one M8x1.25 rod end and a position flag or cam on the other, which resists torsion better than a single rod. The body uses a riveted rolling-packed aluminum barrel with a grease-retaining piston seal, and impact is controlled by a fixed rubber bumper. Note that the rear rod requires clearance in your layout, and the cylinder cannot hold position without live air pressure.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X10S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X10S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 10 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 MBLD20X10S Is Used
PCB Pick-and-Place
Drives a 10 mm vertical pick-and-place head for PCB handling, using the 132 N equal both-way force to lift and place delicate components without drift.
Label Dispenser Cam
Uses the rear rod end to actuate a mechanical cam in a labeling machine, synchronizing the 10 mm stroke with the front tooling.
Small Part Ejector
Ejects small molded plastic parts from a fixture, relying on the twin rods to prevent binding during the short 10 mm retraction.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X10S the Right Cylinder?
At 132 N both ways, this 20 mm bore provides light actuation. If you need less force, there is no smaller MBLD size, so consider an external spring or a different compact series. If you need more power, step up to the 25 mm bore, which provides 206 N at 0.5 MPa. Unlike the single-rod MBL, this MBLD gives you equal extend/retract dynamics. If your application suffers from harsh end-impact, consider the MBLCD variant, which features an adjustable air cushion instead of this model's fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for the double-rod type. The standard PT port thread matches the G1/8 air connection. To replace this unit, match the 20 mm bore, 10 mm stroke, PT thread, Basic mounting, and the -S magnet specification. For any long-stroke use, external guides are recommended to prevent rod bending, though this 10 mm stroke is highly robust.
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 MBLD20X10S FAQ
The MBLD20X10S provides equal force in both directions because the rod exits both ends. It delivers 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical force of 27 kgf at 1.0 MPa.
A double-rod cylinder has a piston rod exiting both end covers, meaning the effective area is identical on both sides. This results in equal extend and retract force and speed, and allows you to mount a secondary mechanism or position flag on the rear rod.
