Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X75S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 75mm 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 MBLD40X75S
The AirTAC MBLD40X75S is a double-acting, double-rod aluminum mini cylinder featuring a Ø16 mm carbon-steel rod exiting both end covers. Because a rod occupies both sides of the piston, the annulus area is identical on extend and retract. This means you get exactly 528 N of force both ways at 0.5 MPa, ensuring perfectly balanced push and pull dynamics for your 75 mm stroke application.
This compact riveted-barrel body includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches to track position. The twin rods provide superior anti-rotation guidance for external loads compared to a single-rod design. You can mount a workpiece on the front rod and a position flag or cam on the rear rod, though you must leave appropriate clearance for that rear protrusion. The fixed rubber bumper softens end-of-travel impact, but note that this cylinder does not hold position without live air pressure.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 75 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 MBLD40X75S Is Used
Printed Circuit Board Stacking
The 528 N equal both-way force and 75 mm stroke securely lift and stack PCBs in an electronics assembly line, using the rear rod to trigger a proximity flag.
Textile Fabric Guiding
Twin 16 mm rods prevent fabric roll twisting during high-speed loom feed changes, utilizing the 739 N output at 0.7 MPa for precise tension control.
Semiconductor Wafer Transfer
The compact riveted aluminum body fits into tight cleanroom gantries, while the balanced extend/retract speed prevents sudden acceleration shocks to delicate silicon wafers.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75S the Right Cylinder?
If you need less force, the next size down is the MBLD32 bore, which yields 346 N both ways at 0.5 MPa. If your application requires more power, stepping up to the MBLD50 bore provides 881 N both ways at 0.5 MPa. This 40 mm bore uses a G1/4 port and an M12x1.25 rod-end thread.
Unlike the single-rod MBL series, this MBLD gives you equal extend and retract forces plus a rear rod for secondary mechanisms. If your machine experiences heavy end-load impacts, consider the MBLCD variant, which features an adjustable air cushion instead of this model's fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option for the double-rod type. To replace this SKU exactly, match the 40 mm bore, 75 mm stroke, 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 MBLD40X75S FAQ
Because a rod exits both ends, the push and pull forces are identical. It delivers 528 N at 0.5 MPa and 739 N at 0.7 MPa in both directions. The theoretical maximum at 1.0 MPa is 108 kgf.
The twin rods provide equal force and speed on extend and retract, plus better anti-rotation resistance for external loads. You can also mount a cam or sensor flag on the rear rod. The S suffix indicates a built-in magnet, allowing you to fit AirTAC CMSG (reed) or DMSG/EMSG (electronic) switches for position detection.
