Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X150 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 150mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150
The AirTAC MBLD20X150 is a compact double-acting double-rod aluminum mini cylinder featuring a 20 mm bore and 150 mm stroke. Because an Ø8 mm carbon-steel rod with 20 µm hard-chrome plating exits both end covers, the annulus piston area is identical on both sides. This yields exactly 132 N of force at 0.5 MPa for both extension and retraction, moving at 30-800 mm/s. The 150 mm travel suits mid-range indexing tasks where a fixed rubber bumper absorbs end-of-stroke impact.
This riveted rolling-packed barrel design uses a heterogeneous two-way grease-retaining piston seal. A key advantage of the twin-rod layout is dual-side guidance: you mount the workpiece on one end and a position flag or cam on the rear protruding rod. Note that overall length equals A + 2 x stroke, so you must leave rear-rod clearance in your enclosure. This base SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 150 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 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 (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 MBLD20X150 Is Used
PCB Shuttle Transfer
Drives a 150 mm transfer stroke for PCB edge-rail shuttles in SMT lines, using the equal 132 N both-way force to push and pull light aluminum carriers without speed variation.
Tensioning Cam Flag
Operates a wire tensioning gate in a spring coiler, mounting the wire guide on the front rod and a physical limit-cam on the rear rod to trigger mechanical cutoff at full extension.
Chip Ejector Pusher
Ejects molded silicone chips from a test socket, utilizing the twin-rod anti-rotation property to keep the 150 mm stroke perfectly straight and prevent binding on the ejector plate.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150 the Right Cylinder?
If you need less force, the neighbouring 20 mm bore is the smallest available size, so you would step up to the MBLD25, which provides 206 N at 0.5 MPa. If your application requires more push or pull, consider the MBLD32, offering 346 N at 0.5 MPa. For applications needing adjustable air cushioning instead of the fixed rubber bumper, choose the MBLCD variant.
Mounting is limited to Basic, FA (flange), or LB (foot); there is no back-cover option or SDB pivot bracket available for this double-rod type. The fluid port is G1/8 with a PT (tapered) thread. Since this is a plain MBLD without a magnet, it cannot hold position without live air—the rod drifts without an external lock. At 150 mm stroke, the small 8 mm rod still needs an external guide to prevent bending under side loads.
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 MBLD20X150 FAQ
The MBLD20X150 provides equal force in both directions due to the double-rod design. It delivers 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
A single-rod cylinder has a larger push force than pull force, but the MBLD20X150 has a rod exiting both ends, making the annulus area and force equal both ways. The rear rod can drive a second mechanism or position flag, though it requires extra rear clearance since overall length is A + 2 x stroke.
