Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X150 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 150mm 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 MBLD40X150
The AirTAC MBLD40X150 is a double-acting, double-rod aluminum mini cylinder featuring a 40mm bore and 150mm stroke. A single piston drives a Ø16mm carbon-steel rod out of both end covers, yielding exactly 528N of force at 0.5 MPa in both extend and retract directions. This 150mm stroke is well-suited for mid-range transfer and indexing tasks requiring balanced bilateral motion.
Because the rear rod protrudes continuously, you must account for an overall length of A plus 2 x stroke in your layout. This rear extension can drive a secondary mechanism or mount a position flag, while the twin-rod geometry naturally resists torsional load. The riveted aluminum barrel houses a fixed rubber bumper to soften end-of-travel impacts, and this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without upgrading to an -S variant.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 150 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 MBLD40X150 Is Used
PCB Edge-Trimming Router
Drives a cutting head on a 150mm travel while the opposing rear rod simultaneously lifts a dust-extraction nozzle, using the 528N bilateral force to maintain balanced chip load.
Textile Loom Tentering
Equal push and pull geometry keeps fabric tension arms centered across the 40mm bore's stroke, preventing weave distortion that asymmetric single-rod lag would cause.
Semiconductor Wafer Shuttle
Uses the twin-rod's anti-rotation properties to shuttle wafer cassettes 150mm between load and process locks, relying on the fixed rubber bumper to soften 739N end stops.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150 the Right Cylinder?
When sizing this 40mm bore, stepping down to the 32mm neighbor drops the bilateral force to 346N at 0.5 MPa, while stepping up to the 50mm bore increases it to 881N. Choose the 40mm when 528N each way hits the sweet spot for your payload. If your application suffers from severe end-impact shock, consider the MBLCD variant which adds adjustable air cushioning, as the base MBLD only relies on a fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for this double-rod body. Note that the fixed bumper is not a locking device—the cylinder will drift without sustained air pressure, so external holding mechanisms are required for fail-safe positioning. To replace this unit, match the 40mm bore, 150mm stroke, G1/4 port, PT thread, and lack of a magnet.
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 MBLD40X150 FAQ
Because the double-rod design creates equal annulus areas on both sides, the force is identical in both directions: 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum theoretical output of 108 kgf at 1.0 MPa.
No, this specific MBLD40X150 SKU does not have the -S code, meaning no internal magnet is fitted. To use AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensors, you must source the MBLD40X150S variant which includes the magnetic piston.
