Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X450 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 450mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 528 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450
The AirTAC MBLD40X450 is a double-acting, double-rod aluminum mini cylinder engineered to deliver equal force and speed in both extend and retract directions. Because a Ø16 mm rod protrudes from both end covers, the annulus area is balanced, yielding 528 N of thrust each way at 0.5 MPa. A 450 mm stroke on a compact 40 mm bore is ideal for traversing wide machine spans where a single rod would normally induce rotational drift.
This configuration uses a fixed rubber bumper to soften end-of-stroke impact and lacks a built-in magnet, meaning it cannot host CMSG, DMSG, or EMSG position sensors without a physical external flag. The riveted rolling-packed barrel and grease-retaining piston seal ensure stable operation, while the twin rods provide dual-side guidance. Remember that overall length equals A + 2 x stroke, so you must leave rear-rod clearance for the protruding back end.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 450 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 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 (Ø40mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MBLD40X450 Is Used
PCB Edge Conveyor Transfer
Drives a 450 mm pusher bar across a wide electronics assembly line, using the twin rods to keep the flat plate perfectly aligned without rotation during board transfer.
Textile Loom Cross-Guide
Actuates a yarn guide carriage over a 450 mm span, exploiting the equal 528 N extend and retract force to maintain consistent tension during bidirectional weaving motions.
Packaging Carton Flap Folder
Synchronizes a rear-mounted cam on the opposing rod end to time a secondary glue applicator, ensuring precise mechanical sequencing over long cardboard packaging strokes.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X450 the Right Cylinder?
If 528 N is excessive for your payload, step down to the 32 mm bore, which yields 346 N at 0.5 MPa. If you need heavier thrust, step up to the 50 mm bore, providing 881 N each way. For this 450 mm stroke, the small 16 mm rod is highly susceptible to bending under side loads; always use an external linear guide to support the load and prevent binding.
This base MBLD model uses a fixed rubber bumper, so choose the MBLCD variant if your mass requires adjustable air cushioning. Mounting is restricted to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. This SKU uses default PT (tapered) threads and has no magnet, so external limit switches are required for position sensing. It will not hold position without live air pressure.
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 MBLD40X450 FAQ
Because the double-rod design has equal piston annulus area on both sides, extend and retract forces are identical: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in -S magnet, so CMSG, DMSG, or EMSG switches cannot detect piston position. You must use external mechanical flags or limit switches, though the rear protruding rod offers a convenient mounting point for a cam.
