Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X35S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X35S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 35mm 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 MBLD40X35S
The AirTAC MBLD40X35S is a double-acting, double-rod aluminum mini cylinder featuring a 40mm bore and 35mm stroke. Because a carbon-steel rod protrudes from both end covers, the effective piston area is identical on extend and retract. This yields exactly 528 N of force at 0.5 MPa in both directions, making it ideal for balanced push-and-pull operations. The built-in magnet (-S) enables position detection via CMSG reed or DMSG/EMSG electronic switches.
This model uses a fixed rubber bumper to soften end-of-travel impacts and relies on a riveted rolling-packed aluminum barrel for compact durability. The twin rods provide inherent anti-rotation guidance, allowing you to mount a primary workpiece on one end and a secondary cam or position flag on the rear rod. Keep in mind the overall length equals the base body length plus twice the stroke, requiring rear clearance for the protruding rod.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X35S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X35S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 35 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 MBLD40X35S Is Used
Pick-and-Place Vacuum Cups
Driving 528N both ways to lift and lower PCB handling vacuum cups, using the rear rod to mount a physical limit flag that triggers a sensor at the exact 35mm transfer point.
PCB Stencil Wiping
Reciprocating a wiper blade across solder paste stencils where equal 528N extend and retract force prevents blade skewing, while the twin rods keep the blade flat without twisting.
Label Applicator Tamp
Tamping labels onto small cartons with a 35mm stroke, using the double-rod symmetry to maintain consistent pressure and prevent the applicator head from rotating during the stroke.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X35S the Right Cylinder?
If your application requires less force, stepping down to the 32mm bore yields 346 N at 0.5 MPa. For heavier tasks, the 50mm bore provides 881 N. The MBLD40X35S features a G1/4 port, an M12x1.25 rod-end thread, and standard PT tapered threads. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for this double-rod type. If you need adjustable air cushioning rather than the fixed rubber bumper, select the MBLCD variant. Note that a plain MBLD does not hold position without live air; the rod will drift, so an external lock is needed for 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 MBLD40X35S FAQ
The MBLD40X35S provides equal force in both directions because the rod occupies both sides of the piston. It delivers 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical 108 kgf at 1.0 MPa.
A double-rod cylinder offers equal extend and retract force and allows you to mount a secondary cam or flag on the rear rod. The S denotes a built-in magnet, enabling CMSG reed or DMSG/EMSG electronic sensor switches to detect rod position.
