Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X30S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X30S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 30mm 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 MBLD40X30S
The AirTAC MBLD40X30S is a double-acting, double-rod aluminum mini cylinder engineered for symmetrical motion. Because a Ø16 mm carbon-steel rod exits both end covers, the annulus area is identical on extend and retract. This yields exactly 528 N of force both ways at 0.5 MPa, making the 30 mm stroke ideal for short, synchronized transfer operations.
The riveted rolling-packed barrel houses a heterogeneous two-way grease-retaining seal, while the fixed rubber bumper absorbs end-of-stroke impact. The built-in magnet (-S) allows CMSG, DMSG, or EMSG switches to track position. Remember that overall length equals A plus twice the stroke, so you must leave rear-rod clearance for the protruding shaft.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X30S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X30S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 30 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 MBLD40X30S Is Used
PCB Edge Guiding
Uses the 528 N equal bidirectional force to center electronic circuit boards during conveyor transfer, preventing asymmetric drift on the 30 mm stroke.
Dual-Side Labeling Head
Mounts the applicator on the front rod and a position flag on the rear protruding rod, allowing an external sensor to verify the 30 mm stroke without interfering with the labeling mechanism.
Connector Seating Jig
Presses rectangular fiber connectors into housings with balanced 739 N at 0.7 MPa, using the twin-rod geometry to keep the pressing plate parallel and resist rotation.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X30S the Right Cylinder?
This 40 mm bore generates 528 N each way. If your application requires less force, step down to the 32 mm bore (346 N); if you need heavier thrust, step up to the 50 mm bore (881 N). For higher kinetic energy loads, consider the MBLCD variant which adds adjustable air cushions, whereas this base MBLD relies on a fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. The PT tapered port thread matches the G1/4 porting. A plain double-rod cylinder drifts without live air pressure, so fit an external locking device if you need strict position holding. To replace this unit, match the 40 mm bore, 30 mm stroke, G1/4 port, PT thread, FA/LB mount, 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 MBLD40X30S FAQ
Because the double-rod design has equal piston area on both sides, force is identical in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum theoretical 108 kgf at 1.0 MPa.
A single-rod cylinder has unequal areas and faster retract speeds, while this double-rod cylinder provides equal force and speed both ways. The rear protruding rod can also drive a secondary mechanism or mount a position flag, though it requires rear clearance.
