Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X150S 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 MBLD40X150S
The AirTAC MBLD40X150S is a compact, double-acting double-rod aluminum mini cylinder. A Ø16 mm carbon-steel rod protrudes from both end covers, yielding an identical annulus piston area on each side. This means extend and retract forces are perfectly balanced at 528 N at 0.5 MPa, preventing the speed asymmetry found in single-rod units. The 150 mm stroke suits mid-travel positioning tasks.
The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track position from either side. A rod exits both ends, so you can mount the primary workpiece on the front and a mechanical cam or position flag on the rear. The riveted rolling-packed barrel houses a grease-retaining piston seal, and end-of-travel impact is absorbed by a fixed rubber bumper. Overall length equals the base body length plus twice the stroke, requiring rear-rod clearance in your layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150S |
|---|---|
| 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 MBLD40X150S Is Used
PCB Stencil Wiping
Drives a dual-sided squeegee on an SMT line; the equal 528 N force ensures consistent paste distribution on both forward and return strokes over the 150 mm travel.
Textile Guiding Cam
Mounts a fabric spreader on the front rod and a mechanical limit flag on the rear protruding rod to trigger loom timing, using the twin-rod design to resist yarn tension rotation.
Tray Elevator Transfer
Transfers empty semiconductor wafer trays between vertical buffers; the 150 mm stroke shifts the load while the twin rods keep the platform guided without binding.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X150S the Right Cylinder?
If 528 N is excessive, step down to the MBLD32 bore, which yields 346 N at 0.5 MPa. If your payload requires more push, step up to the MBLD50 bore, providing 881 N at 0.5 MPa. The G1/4 port matches the 40 mm bore sizing. The -S code confirms the magnet is present; without it, a plain MBLD40X150 cannot accept CMSG or DMSG sensors.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for the double-rod series. The fixed rubber bumper softens end impacts but does not lock the rod—the cylinder drifts without live air, so use an external locking device for position holding. For high kinetic energy loads, consider the MBLCD variant which adds adjustable air cushions.
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 MBLD40X150S FAQ
Because the double-rod design creates equal annulus areas on both sides, the output force is identical in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical 108 kgf at 1.0 MPa.
A rod exits both ends, allowing you to drive a primary mechanism on one side and mount a cam or position flag on the rear, while providing better anti-rotation guidance than a single rod. The -S suffix means a built-in magnet is fitted, enabling CMSG reed or DMSG/EMSG electronic sensors to detect piston position.
