Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X80S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 80mm 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 MBLD20X80S
The AirTAC MBLD20X80S is a compact, double-acting double-rod aluminum mini cylinder. Because an 8mm rod exits both end covers, the annulus area is identical on extend and retract, yielding 132N of force each way at 0.5 MPa. An 80mm stroke on a 20mm bore is ideal for light-duty positioning in tight spaces. The built-in magnet (-S) allows CMSG, DMSG, or EMSG sensor switches to track rod position.
This configuration uses a fixed rubber bumper to soften end-of-travel impacts rather than an adjustable air cushion. The riveted rolling-packed aluminum barrel and 20um hard-chrome plated carbon-steel rod provide durable service. Since the rear rod protrudes, you must account for it in your layout—overall length equals the base body length plus twice the stroke. You can mount a workpiece on one end and a position flag or cam on the other for dual-side guidance.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 80 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 MBLD20X80S Is Used
PCB Edge Guiding
Drives a lightweight guide rail on a printed circuit board conveyor, using the twin 8mm rods to prevent binding and ensuring 132N of equal force during extension and retraction.
Pick-and-Place Flag
Actuates a small electronic component gripper on the front rod while the rear rod carries a physical flag to trigger a DMSG electronic sensor at 80mm travel.
Label Applicator Cam
Pushes a thin film label onto packaging with equal 185N force at 0.7 MPa, using the opposing rod end to mount a cam that synchronizes a secondary glue roller.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80S the Right Cylinder?
For 132N of equal bidirectional force at 0.5 MPa, this 20mm bore is the smallest available in the MBLD range. If your application requires less force, you must step down to a single-rod MBL cylinder, as no smaller double-rod bore exists. If you need more power, step up to the 25mm bore, which provides 206N each way at 0.5 MPa. If your cycle speed demands adjustable end-cushioning rather than the fixed rubber bumper found here, choose the MBLCD variant.
Mounting is limited to Basic, FA (flange), or LB (foot) brackets; there is no SDB pivot or back-cover option for the double-rod design. This cylinder has PT (tapered) ports and a G1/8 thread size. Note that a plain MBLD does not hold position without live air—the rod drifts without pressure. For exact replacement matching, verify the 20mm bore, 80mm stroke, PT thread, and the -S magnet requirement.
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 MBLD20X80S FAQ
Because the double-rod design has equal annulus areas on both sides, the force is identical in both directions: 132N at 0.5 MPa, 185N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
A single-rod cylinder has a larger push force than pull force due to the rod occupying piston area. The MBLD20X80S has an 8mm rod exiting both ends, making push and pull forces equal. This rear rod protrudes and can drive a second mechanism, but it requires rear clearance and cannot use an SDB pivot bracket.
