Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X50
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X50 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 50mm 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 MBLD40X50
The AirTAC MBLD40X50 is a double-acting, double-rod aluminum mini cylinder engineered for applications requiring equal force in both directions. Because a Ø16 mm carbon-steel rod with 20 um hard-chrome plating exits both end covers, the effective piston area is identical on extend and retract. This yields 528 N of thrust each way at 0.5 MPa, making the 50 mm stroke highly predictable for rapid, symmetrical cycling. The riveted rolling-packed barrel keeps the body light for tight machine spaces.
This configuration uses a fixed rubber bumper to soften end-of-stroke impacts and lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. A major advantage of the through-rod design is dual-side guidance: you can mount the primary workpiece on the front rod and a cam or position flag on the rear rod. Note that overall length equals the base body plus twice the stroke, so you must leave physical clearance at the back for the protruding rod.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X50 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X50 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 50 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 MBLD40X50 Is Used
PCB Depaneling Saw Feed
Drives a circular blade forward and back with equal 528 N force at 0.5 MPa, ensuring a consistent 50 mm cut depth without asymmetric speed drift.
Textile Loom Tensioner
Uses the twin-rod symmetry to push a yarn guide bar out and retract it at identical speeds, preventing fabric distortion during high-speed loom cycling.
Encoder Cam Actuation
Mounts the primary work tool on the front rod while the rear rod end protrudes to trigger a mechanical limit switch cam in a compact packaging machine.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X50 the Right Cylinder?
Select this 40 mm bore when your mechanism needs exactly 528 N at 0.5 MPa (739 N at 0.7 MPa) in both advance and retract. If your payload is lighter, stepping down to the 32 mm bore drops the bidirectional force to 346 N at 0.5 MPa; for heavier loads, the 50 mm bore increases it to 881 N. This SKU uses a PT tapered thread and a G1/4 port. Mounting is limited to Basic, FA flange, or LB foot brackets—MBLD does not support SDB pivot or back-cover mounting. For exact replacements, match the 40 mm bore, 50 mm stroke, PT thread, and lack of -S magnet. If you need adjustable air cushions instead of fixed rubber bumpers, choose the MBLCD variant. Remember that this cylinder does not hold position without live air; use an external locking device if drift is unacceptable.
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 MBLD40X50 FAQ
Because it is a double-rod cylinder, the extend and retract forces are equal. It provides 528 N at 0.5 MPa and 739 N at 0.7 MPa in both directions. The maximum theoretical force is 108 kgf at 1.0 MPa.
No. This specific SKU lacks the built-in magnet (denoted by -S), so it cannot host CMSG reed or DMSG/EMSG electronic switches. You must use external mechanical flags or limit switches for position detection.
