Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X450S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X450S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø32mm bore and 450mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 346 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X450S
The AirTAC MBLD32X450S is a double-acting, double-rod aluminum mini cylinder featuring a 32mm bore and 450mm stroke. Because a Ø12mm rod exits both end covers, the annulus area is identical on each side, yielding exactly 346 N of force in both extend and retract directions at 0.5 MPa. The built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensors for mid-stroke position detection.
This 450mm travel length requires careful rear-rod clearance, as overall length grows by twice the stroke. A fixed rubber bumper absorbs end-of-travel impacts, while the riveted rolling-packed barrel and hard-chrome carbon-steel rod provide durable service in compact spaces. Note that long-stroke twin rods still need an external guide to prevent bending under side loads.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X450S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X450S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø32 mm |
| Stroke | 450 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 (Ø32mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 MBLD32X450S Is Used
PCB Edge Conveyor Tracking
Drives a dual-sided sync alt mechanism in a PCB conveyor, using the rear rod end to mount a position flag that triggers an electronic DMSG sensor at 450mm travel.
Semiconductor Wafer Shuttle
Transfers wafer cassettes between process chambers with equal 346 N push and pull force, ensuring balanced deceleration without rotational torque on the 32mm twin rods.
Textile Loom Tensioner
Actuates a fabric guide bar over a 450mm stroke, leveraging the double-rod geometry to keep the light load guided against twisting while maintaining steady tension.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X450S the Right Cylinder?
At 0.5 MPa, this 32mm bore delivers 346 N both ways. If your application requires less force, step down to the 25mm bore (206 N both ways); if you need more power, step up to the 40mm bore (528 N both ways). For high kinetic energy at this 450mm stroke, consider the MBLCD variant which adds adjustable air cushions, whereas the base MBLD relies on a fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option.
A replacement requires matching the 32mm bore, 450mm stroke, G1/8 port, and M10x1.25 rod thread. The default port thread is PT; specify G or NPT if needed. This plain MBLD does not hold position without live air—the rod drifts when pressure drops, so fit an external locking device for fail-safe holding. With a 450mm stroke, always use an external guide to manage rod deflection.
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 MBLD32X450S FAQ
Because the MBLD32X450S has a rod on both sides, the effective piston area is equal in both directions. The output force is 346 N at 0.5 MPa and 484 N at 0.7 MPa for both extend and retract. The maximum theoretical force is 71 kgf at 1.0 MPa.
A single-rod cylinder has a larger push force than pull force due to the rod occupying one side. The MBLD32X450S double-rod design makes push and pull forces equal, and allows you to mount a cam, second tool, or position flag on the rear rod end. It also provides better resistance to rotation, though external guides are still recommended for this 450mm stroke.
