Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X500
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X500 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø32mm bore and 500mm 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 MBLD32X500
The AirTAC MBLD32X500 is a double-acting, double-rod aluminum mini cylinder engineered for applications demanding equal force in both directions. Because a Ø12mm carbon-steel rod with 20µm hard-chrome plating exits both end covers, the annulus area is identical on extend and retract, yielding a symmetrical 346N at 0.5MPa and 484N at 0.7MPa each way. At a 500mm stroke, this model suits long-travel transfer and indexing tasks while maintaining a compact riveted barrel profile.
A defining mechanical trait of this twin-rod layout is the elimination of single-rod push/pull disparity, alongside built-in dual-side guidance that resists torsional rotation better than a single rod. The overall length equals A + 2 x stroke, meaning the rear rod protrudes significantly and requires dedicated clearance. Impact is managed by a fixed rubber bumper at each end. Note this specific SKU lacks a built-in magnet (-S), so it cannot host CMSG, DMSG, or EMSG position sensors.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X500 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø32 mm |
| Stroke | 500 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 MBLD32X500 Is Used
PCB Edge Conveyor Transfer
Drives a 500mm pusher arm that transfers printed circuit boards between inspection stations, utilizing the twin-rod anti-rotation property to keep the pusher plate perfectly level without external guides.
Textile Yarn Carriage Indexing
Shifts a yarn carriage back and forth across a 500mm winding width, relying on the equal 484N force at 0.7MPa to maintain consistent tension on both the extend and retract strokes.
Semiconductor Wafer Cassette Ejector
Ejects wafer cassettes from a loading dock using the protruding rear rod to trip a mechanical limit flag, confirming full extension without needing an internal magnetic sensor.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X500 the Right Cylinder?
When sizing this 32mm bore, step down to the 25mm version for 206N at 0.5MPa, or step up to the 40mm bore for 528N at 0.5MPa. The MBLD32X500 uses a G1/8 port and PT thread form. If your application requires adjustable pneumatic cushioning rather than fixed rubber bumpers, migrate to the MBLCD variant. Mounting is strictly limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option.
Because this cylinder operates at its maximum standard stroke of 500mm, the slender Ø12mm rod is highly susceptible to side-loading and buckling under off-center loads. Even with twin rods providing anti-rotation benefits, an external linear guide rail must be installed to prevent rod bending. Furthermore, the fixed rubber bumper only softens end-of-stroke impact; it does not lock position, so external holding devices are required if air pressure drops.
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 MBLD32X500 FAQ
Because the double-rod design creates equal piston annulus areas on both sides, the push and pull forces are identical: 346N at 0.5MPa, 484N at 0.7MPa, and a maximum theoretical 71kgf at 1.0MPa.
A rod exits both ends, making extend and retract forces perfectly equal and providing better resistance to torsional rotation. The rear rod can also drive a secondary mechanism or cam. However, because this SKU lacks the -S magnet, it cannot be fitted with CMSG reed or DMSG electronic sensors.
