Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X150S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X150S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 150mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X150S
The AirTAC MBLD50X150S is a double-acting, double-rod aluminum mini cylinder featuring a 50mm bore and 150mm stroke. A single piston drives a Ø16mm carbon-steel rod out of both end covers, yielding exactly 881 N of force at 0.5 MPa on both extend and retract strokes. Because the annulus area is identical on both sides, push and pull forces are perfectly balanced. The -S suffix indicates a built-in magnet for position detection using CMSG reed or DMSG/EMSG electronic switches.
This model features a riveted rolling-packed aluminum barrel and a fixed rubber bumper to soften end-of-stroke impact. The twin-rod design naturally resists torsional rotation, allowing you to mount a workpiece on the front rod and a cam or position flag on the rear rod. Keep in mind the overall length equals A + 2 x stroke, so you must leave rear-rod clearance in your machine layout. The bumper is not a locking device; the rod will drift without live air pressure.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X150S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X150S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 150 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M14×1.5 |
| 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 (Ø50mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 MBLD50X150S Is Used
Textile Loom Beater
Drives a loom beating mechanism where the 881 N equal both-way force ensures consistent weft packing on both the forward and return strokes without speed variation.
PCB Edge Trimmer
Pushes a cutting blade on the front rod while the rear rod protrudes 150mm to trip an external reed sensor, verifying full extension before the cut initiates.
Packaging Flap Folder
Folds heavy cardboard flaps simultaneously; the twin-rod construction prevents the load from twisting during the 150mm travel, maintaining precise alignment.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X150S the Right Cylinder?
If your application requires slightly less force, stepping down to the 40mm bore variant provides 528 N at 0.5 MPa, saving space. For heavier drives, stepping up to the 63mm bore yields 1457 N at 0.5 MPa. The MBLD50X150S uses a G1/4 port and M14x1.5 rod-end thread. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for the double-rod series. If your machine needs adjustable air cushioning rather than the fixed rubber bumper, select the MBLCD variant instead. When replacing this unit, match the 50mm bore, 150mm stroke, PT thread, and -S magnet specification.
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 MBLD50X150S FAQ
Because a rod exits both ends, the effective piston area is equal on both sides. The force is 881 N at 0.5 MPa and 1233 N at 0.7 MPa in both extend and retract directions. The maximum theoretical force is 180 kgf at 1.0 MPa.
The double-rod design means a rod protrudes from both ends, providing equal force and speed both ways while allowing you to mount a cam or position flag on the rear rod. The -S suffix means a magnet is built into the piston, allowing you to attach CMSG reed or DMSG/EMSG electronic sensors for position detection.
