Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 80mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Adjustable air cushion (both ends).

About the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80
The AirTAC MBLCD50X80 is a compact double-acting double-rod aluminum mini cylinder featuring an adjustable air cushion at both ends. Because a Ø16 mm rod exits both covers, the effective annulus area is identical on extend and retract, yielding exactly 881 N of force each way at 0.5 MPa. The 80 mm stroke suits short-travel lifting and gripping tasks.
The screw-tunable cushions decelerate the piston near end-of-stroke to protect the end covers during faster or heavier twin-rod moves, a clear upgrade over the fixed rubber bumper found on the base MBLD. The rear rod protrudes equally, allowing you to mount a cam or flag on the backside for external tracking while the twin-rod geometry resists torsional rotation. Note this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.
Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80 Technical Specifications
| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 80 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 | Adjustable air cushion (both ends) |
| 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 MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80 Is Used
Thermoforming Press Platen
Drives a 50 mm bore twin-rod platen in a small thermoforming press, utilizing the 881 N equal both-way force to mold and release plastic sheets without rotational deflection.
Textile Loom Guide
Actuates a synchronized yarn guide bar on a textile loom, where the adjustable air cushion absorbs the 80 mm stroke impact to prevent end-cover damage during rapid loom cycling.
PCB Conveyor Diverter
Shifts a dual-sided diverter arm on a PCB conveyor, using the rear protruding rod to trigger a mechanical flag while the front rod pushes panels at 1233 N at 0.7 MPa.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80 the Right Cylinder?
If 881 N is excessive for your payload, step down to the 40 mm bore, which provides 528 N at 0.5 MPa. If you need heavier pushing or pulling, step up to the 63 mm bore, which generates 1457 N at 0.5 MPa. Choose this MBLCD over the single-rod MBLC when your mechanism requires dual-side guidance, a rear-mounted cam, or strict anti-rotation resistance.
Mounting is strictly limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot option and no back-cover CA/U mounting code. The standard PT port thread matches the G1/4 porting. A plain MBLCD does not hold position without live air—the rod drifts when pressure drops, and the cushion only decelerates near the ends rather than mechanically locking the load.
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 MBLCD Aluminum Alloy Mini Cylinder MBLCD50X80 FAQ
Because a rod occupies both sides, the push and pull forces are equal. This 50 mm bore cylinder provides 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a theoretical maximum of 180 kgf at 1.0 MPa in both directions.
No. This specific SKU lacks the built-in magnet (denoted by an -S suffix), so it cannot accept CMSG reed or DMSG/EMSG electronic sensors. The adjustable air cushion is screw-tunable for end-of-stroke deceleration, but it is not a mechanical lock.
