Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X80 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 MBLD20X80
The AirTAC MBLD20X80 is a double-acting, double-rod aluminum mini cylinder featuring an 8 mm carbon-steel rod protruding from both end covers. Because a rod occupies both sides of the piston, the annulus area is identical in both directions, yielding exactly 132 N of thrust and retraction force at 0.5 MPa. The 80 mm stroke is ideal for short-transfer tasks, while the twin-rod layout naturally resists torsion and keeps light loads guided without twisting.
This compact body uses a riveted rolling-packed barrel and a fixed rubber bumper at the stroke ends to soften impact. Lacking the -S suffix, this specific SKU has no built-in magnet and cannot host CMSG or DMSG position sensors. Overall length equals the base body plus twice the stroke, so you must leave rear-rod clearance in your layout to prevent mechanical binding.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80 |
|---|---|
| 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 MBLD20X80 Is Used
PCB Pick-and-Place
Drives a small vacuum gripper across an 80 mm stroke to lift delicate printed circuit boards, using the equal 132 N both-way force to ensure consistent placement and retraction without speed drift.
Label Feed Indexing
Advances a web labeling mechanism where the twin rods prevent torsional deflection, keeping the 8 mm rod-end tool perfectly aligned during high-speed 80 mm strokes.
Rear Cam Actuation
Mounts a cam on the rear protruding rod to trip a mechanical micro-switch at mid-stroke, utilizing the dual-sided output for synchronized machine timing.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X80 the Right Cylinder?
If you need slightly less output, stepping down to the MBLD16 bore is not an option as 20 mm is the smallest available size. Stepping up to the MBLD25 bore raises your bidirectional force to 206 N at 0.5 MPa. Keep in mind the MBLD20X80 uses a fixed rubber bumper; if your payload carries high kinetic energy and requires adjustable end-cushioning, choose the MBLCD variant instead. For a lighter single-rod setup, the standard MBL series works, but you lose the equal both-way force.
Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option for the double-rod series. The G1/8 port and PT thread form the standard connection. Because this plain SKU lacks a magnet, you cannot track rod position electronically; if you need end-of-stroke signaling, specify the -S code for a reed or solid-state switch. The rubber bumper only softens end impact; it does not lock the rod, so external mechanical holding is required if power fails.
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 MBLD20X80 FAQ
Because the MBLD20X80 is a double-rod cylinder, the effective piston area is identical on both sides. The force is equal in both extend and retract directions: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
No. This specific MBLD20X80 SKU lacks the built-in magnet (-S code), meaning AirTAC CMSG reed or DMSG electronic sensors cannot detect rod position. You must select an MBLD20X80S variant if your application requires electronic end-of-stroke signaling.
