Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X150S 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 MBLD20X150S
The AirTAC MBLD20X150S is a double-acting, double-rod aluminum mini cylinder featuring a 20mm bore and 150mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 132 N each way at 0.5 MPa. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic switches to track piston position. This 150mm travel suits intermediate indexing tasks where a rear rod can drive a secondary mechanism.
The riveted rolling-packed aluminum barrel houses a 20 um hard-chrome plated carbon-steel rod and a grease-retaining piston seal. End-of-stroke impact is absorbed by a fixed rubber bumper. Overall length equals A + 2 x stroke, meaning the rear rod protrudes equally and requires clear space to avoid collision. Mounting is limited to Basic, FA flange, or LB foot options, as no back-cover or SDB pivot exists for this twin-rod format.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150S |
|---|---|
| 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 MBLD20X150S Is Used
PCB Depaneling Saw
Drives a circular blade on the front rod while the rear rod mounts a position flag to trigger an optical sensor, ensuring 132 N of consistent cutting pressure both directions.
Connector Insertion Jig
Pushes rectangular headers into sockets with equal push and pull force, using the twin rods to resist rotational torque during dense PCB assembly.
Label Dispenser Arm
Extends 150mm to peel release liners via a dual-sided pickup head, relying on the symmetric retract speed to maintain web tension without tearing.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X150S the Right Cylinder?
When sizing this 20mm bore, step down is not an option as it is the smallest available. Stepping up to the 25mm bore raises the bidirectional force to 206 N at 0.5 MPa. Choose the MBLD over the single-rod MBL when a project demands equal push/pull dynamics, dual-side guidance, or a rear rod for a cam. For high-cycle applications needing end-deceleration, select the MBLCD variant which features adjustable air cushions instead of the fixed rubber bumper. Replacement requires matching the 20mm bore, 150mm stroke, G1/8 PT port, and the -S magnet. At 150mm travel, the 8mm rod is susceptible to bending under lateral loads, so an external guide rail should support the payload.
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 MBLD20X150S FAQ
Because the rod occupies both sides of the piston, push and pull forces are identical: 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 unequal extend and retract forces due to the rod displacing piston area. The MBLD double-rod design makes these forces equal and allows the rear rod extension to mount a secondary cam, limit flag, or second tool.
