Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X500S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X500S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 500mm 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 MBLD40X500S
The AirTAC MBLD40X500S is a double-acting, double-rod mini cylinder featuring a 40mm bore and 500mm stroke. Because a Ø16mm rod protrudes from both end covers, the annulus area is identical on each side, delivering an equal 528N of force in both directions at 0.5 MPa. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track piston position. A 500mm stroke on a compact body is ideal for traversing wide machine envelopes while maintaining a small footprint.
This model uses a G1/4 port and M12x1.25 rod-end thread. The riveted aluminum barrel houses a grease-retaining piston seal and a hard-chrome plated carbon-steel rod. Overall length equals A + 2 x stroke, meaning the rear rod extends significantly and requires dedicated clearance. Impact is absorbed by a fixed rubber bumper at the stroke ends, which softens stops but does not lock the load.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X500S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X500S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 500 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 MBLD40X500S Is Used
PCB Edge Conveyor Transfer
Uses the 500mm stroke to push assembled PCB panels across a wide conveyor gap, relying on the 528N equal both-way force to extend and retract the transfer arm at consistent speeds.
Vision System Shuttle
Drives a dual-sided camera shuttle where the rear rod mounts a physical position flag, ensuring the twin-rod geometry keeps the sensor bracket aligned without rotational drift.
Textile Web Spreader
Actuates a long-travel spreader bar in textile machinery, utilizing the 40mm bore's 739N at 0.7 MPa to tension fabric evenly while the fixed rubber bumpers prevent harsh end-jarring.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X500S the Right Cylinder?
At 500mm stroke, the Ø16mm twin rods provide better rotational stability than a single rod, but the extended length makes the cylinder susceptible to side-loading and rod bending under heavy offset masses—an external linear guide is mandatory. If you need less reach or force, the 32mm bore offers 346N at 0.5 MPa; stepping up to the 50mm bore yields 881N for heavier payloads.
This SKU includes a built-in magnet for position detection and uses default PT tapered ports. Mounting is limited to Basic, FA flange, or LB foot brackets—no SDB pivot or back-cover options exist. For applications requiring adjustable end-cushioning to absorb high kinetic energy, select the MBLCD variant instead. A plain MBLD will drift if air pressure drops, so use an external locking device for fail-safe 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 MBLD40X500S FAQ
Because the double-rod design has equal piston area on both sides, push and pull forces are identical: 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum theoretical 108 kgf at 1.0 MPa.
A rod exits both ends, making extend and retract forces equal and providing better anti-rotation guidance. The rear rod can mount a cam or position flag, but note that the overall length is A + 2 x stroke, requiring rear clearance.
