Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X75 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 MBLD40X75
The AirTAC MBLD40X75 is a double-acting, double-rod aluminum mini cylinder featuring a 40mm bore and 75mm 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 75mm travel tasks requiring symmetrical thrust and consistent speed both ways.
Because a rod protrudes from the rear cover, you can mount a position flag or cam on one end while driving the primary load on the other. The riveted aluminum barrel and grease-retaining seal protect internal components, while the fixed rubber bumper absorbs end-of-travel impacts. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75 |
|---|---|
| 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 MBLD40X75 Is Used
PCB Router Spindle
Drives a 75mm routing stroke on a PCB depaneling router, using the 528N bidirectional force to cleanly cut fringes while the twin rods keep the blade aligned.
Textile Beam Reverser
Actuates a reversing flag on a textile loom beam, leveraging the equal extend and retract speeds to maintain consistent tension across 75mm of travel.
Vision System Ejector
Pushes rejected microchips out of a vision inspection station, mounting a secondary ejector pin on the rear rod to clear debris simultaneously.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X75 the Right Cylinder?
Stepping down, the 32mm bore provides 346 N at 0.5 MPa, which may suffice for lighter duties. Stepping up, the 50mm bore yields 881 N at 0.5 MPa for heavier loads. If your application requires adjustable air cushioning rather than the fixed rubber bumper found here, select the MBLCD variant. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for this double-rod body. When replacing, verify the 40mm bore, 75mm stroke, G1/4 port, PT thread, and lack of magnet. This cylinder does not hold position without live air—the bumper is not a lock.
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 MBLD40X75 FAQ
The MBLD40X75 provides equal force in both directions due to the double-rod design. 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.
A double-rod cylinder has a rod exiting both ends, meaning the effective piston area is identical on both sides for equal push and pull force. You can use the rear rod for a cam or secondary mechanism. This specific MBLD40X75 SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.
