Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X40
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X40 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 40mm 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 MBLD40X40
The AirTAC MBLD40X40 is a double-acting, double-rod aluminum mini cylinder featuring a 40 mm bore and 40 mm stroke. Because a 16 mm carbon-steel rod protrudes from both end covers, the effective piston area is identical on extend and retract. This yields 528 N of force both ways at 0.5 MPa (739 N at 0.7 MPa), making it ideal for short 40 mm transfer or indexing tasks needing symmetric thrust.
The riveted rolling-packed barrel keeps the compact body light for tight spaces, while the 20 um hard-chrome plating protects the rod. End-of-stroke impact is absorbed by a fixed rubber bumper. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. You can mount a workpiece on the front rod and a cam or position flag on the rear rod, but you must leave clearance for that rear rod since overall length equals A plus 2 x stroke.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X40 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X40 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 40 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 MBLD40X40 Is Used
PCB Stacking Shuttle
Drives a 40 mm shuttle stroke to push printed circuit boards into testing trays, using the equal 528 N thrust both directions for consistent feed and return without momentum drift.
Twin-Spindle Winder
Mounts a yarn guide on the front rod and a mechanical trip flag on the rear rod to trigger a bobbin changeover, leveraging the anti-rotation stability of the twin 16 mm rods.
Edge-Glue Applicator
Indexes a 40 mm stroke to apply adhesive to semiconductor lead frames, relying on the symmetric extend and retract speeds to maintain a uniform 0.5 MPa dispensing profile.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X40 the Right Cylinder?
If your drive requires less thrust, stepping down to the 32 mm bore provides 346 N both ways at 0.5 MPa; if you need more power, the 50 mm bore yields 881 N. This base MBLD uses a fixed rubber bumper, so for higher kinetic energy cycles, consider the MBLCD variant which adds adjustable air cushioning. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no back-cover or SDB pivot option. To match this cylinder for replacement, verify the 40 mm bore, 40 mm stroke, G1/4 port, default PT thread, and no magnet. Remember that the rubber bumper softens impact but does not lock the rod; this cylinder will drift without live air, so use an external locking device for position holding.
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 MBLD40X40 FAQ
The MBLD40X40 provides equal force in both directions because the 16 mm rod occupies both piston sides. It delivers 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical output of 108 kgf at 1.0 MPa.
Unlike a single-rod MBL where push force exceeds pull force, the MBLD double-rod design yields identical thrust and speed both ways. The rear protruding rod also allows you to mount a cam or secondary mechanism, but you must leave rear clearance since the rod exits both ends.
