Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X450
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X450 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 450mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X450
The AirTAC MBLD50X450 is a double-acting, double-rod aluminum mini cylinder engineered for tasks requiring equal force and speed in both directions. Because a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating exits both end covers, the annular piston area is identical on extend and retract, yielding 881 N at 0.5 MPa and 1233 N at 0.7 MPa each way. The 450 mm stroke is ideal for traversing wide machine bays, while the riveted rolling-packed barrel keeps the compact body lightweight.
This configuration uses a G1/4 port and a fixed rubber bumper to soften end-of-travel impact. As this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors. The twin-rod design inherently resists torsional rotation better than a single rod, allowing a rear-mounted cam to trip a mechanical limit switch while the front rod drives the payload. Remember that the rear rod protrudes, so overall length equals A plus twice the stroke—designate adequate rear clearance.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X450 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X450 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 450 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 | Fixed rubber bumper |
| 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 MBLD Dual Axis Type Mini Cylinder MBLD50X450 Is Used
Injection Mold Ejection
Uses the 881 N bidirectional force to push a 450 mm ejector bar, retracting a rear-mounted flag to confirm mold open status without a pneumatic sensor.
Pallet Transfer Line
Drives a 450 mm stroke pusher across a 400 mm wide conveyor, leveraging the twin-rod anti-rotation to keep the pushing plate perfectly vertical under offset loads.
Textile Calendering
Applies constant 1233 N tension at 0.7 MPa across a wide fabric web, using the equal retract force to maintain uniform material wind-up tension.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X450 the Right Cylinder?
Stepping down to the 40 mm bore drops the bidirectional force to 528 N at 0.5 MPa, which may suffice for lighter transfer assemblies, while stepping up to the 63 mm bore provides 1457 N at 0.5 MPa for heavier mold shifting. At 450 mm, this unit is near the 500 mm standard maximum for this bore; long strokes amplify side-load bending on the 16 mm rod, so an external linear guide is mandatory to prevent premature seal wear.
Unlike the single-rod MBL, this MBLD guarantees symmetrical velocity for synchronized dual-action. If decelerating a 1233 N load at high speed causes bumper wear, upgrade to the MBLCD variant for adjustable pneumatic cushioning. Mounting is restricted to Basic, FA flange, or LB foot brackets—SDB pivot and back-cover options are unavailable. The default PT thread must be matched exactly when replacing; a plain MBLD50X450 without -S cannot support electronic sensing.
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 MBLD50X450 FAQ
Because the double-rod design has equal piston annulus area on both sides, the extend and retract forces are identical: 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a maximum of 180 kgf (1765 N) at 1.0 MPa.
No, this specific MBLD50X450 SKU lacks the -S magnet suffix, meaning no internal magnet is fitted and CMSG/DMSG/EMSG switches cannot detect rod position. You must use an external mechanical flag on the rear rod, or choose an MBLD50X450S variant for electronic sensing.
