Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X400S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X400S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 400mm 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 MBLD40X400S
The AirTAC MBLD40X400S is a double-acting, double-rod mini cylinder featuring a 40mm bore and 400mm stroke. A single piston drives a Ø16mm carbon-steel rod out of both end covers, yielding exactly 528 N of force at 0.5 MPa in both extend and retract directions. This equal annulus area makes it ideal for synchronized dual-side operations. The built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensors for mid-stroke position detection.
Because the rear rod protrudes during operation, you must leave clearance for its 400mm travel. The riveted rolling-packed aluminum barrel keeps the body compact, while the fixed rubber bumper absorbs end-of-stroke impact. The 400mm length requires careful external guidance to prevent rod bending under side loads.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X400S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X400S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 400 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 MBLD40X400S Is Used
Textile Loom Takedown
Drives a synchronized takedown roller on the front rod while a rear rod cam trips a limit flag, using 528 N of equal both-way force to maintain fabric tension.
PCB Conveyor Width Gate
Adjusts a guide rail 400mm across the production line; the twin-rod design prevents the 16mm rod from twisting under asymmetric conveyor belt friction.
Semiconductor Wafer Elevator
Raises and lowers a wafer cassette stage; the DMSG electronic sensor tracks the 400mm stroke while the double-rod configuration balances the lift load.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X400S the Right Cylinder?
For lower force needs, step down to the 32mm bore (346 N @0.5 MPa); for heavier drives, step up to the 50mm bore (881 N @0.5 MPa). Choose the MBLCD variant if your cycle speeds demand adjustable air cushioning rather than the standard fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option. A plain MBLD does not hold position without live air—the rod drifts—so use an external lock for static holding. When replacing, verify the 40mm bore, 400mm stroke, G1/4 port, PT thread, and -S 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 MBLD40X400S FAQ
Because a rod occupies both sides of the piston, the effective annulus area is identical in both directions. Force is equal both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical 108 kgf at 1.0 MPa.
A single-rod cylinder has unequal push/pull forces, but the MBLD double-rod provides equal force and speed both ways. The rear protruding rod can drive a second mechanism or position flag. The S suffix indicates a built-in magnet for AirTAC CMSG (reed) and DMSG/EMSG (electronic) sensor switches.
