Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X175S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X175S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 175mm 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 MBLD50X175S
The AirTAC MBLD50X175S 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, yielding exactly 881 N of force each way at 0.5 MPa. The 175 mm stroke is well within the 500 mm standard limit for this bore, making it ideal for mid-travel transfer tasks. A built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track piston position.
This configuration uses a G1/4 port and M14x1.5 rod-end threads. The riveted rolling-packed barrel houses a fixed rubber bumper to soften end-of-stroke impact. Since the overall length equals the body plus twice the stroke, you must leave physical clearance at the rear for the protruding rod. This twin-rod layout naturally resists torsional rotation better than a single-rod unit, allowing a cam or position flag to be mounted on the opposite end to trigger external limit switches.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X175S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X175S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 175 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 MBLD50X175S Is Used
PCB Conveyor Gate
Lifts and lowers a hinged conveyor section in a PCB assembly line. The 175 mm stroke clears the 150 mm board transfer height, while the twin rods keep the gate level without twisting under the 881 N load.
Textile Beam Shift
Transfers warp beams between loading cradles. The rear protruding rod drives a mechanical flag that signals the creel loader, utilizing the equal extend and retract speed to maintain rhythmic loom feeding.
Wafer Cassette Elevator
Raises semiconductor wafer cassettes between process stations. The -S magnet triggers DMSG electronic sensors for precise vertical positioning, while the fixed rubber bumper prevents jarring at the 175 mm travel ends.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD50X175S the Right Cylinder?
Select this 50 mm bore when an application demands 881 N of symmetrical force at 0.5 MPa. If your payload is lighter, stepping down to the 40 mm bore drops the equal both-way output to 528 N while saving space. For heavier payloads, the 63 mm bore raises it to 1457 N. The PT thread form matches standard tapered pneumatic fittings.
Unlike the single-rod MBL series, this MBLD variant provides equal push/pull dynamics and dual-side mounting. If shock absorption is inadequate, the MBLCD variant offers adjustable air cushions. Mounting is limited to Basic, FA flange, or LB foot brackets—there is no SDB pivot or back-cover option. Note that the fixed rubber bumper softens impact but does not lock the rod; the cylinder will drift without live air pressure. At 175 mm of travel, external guides are recommended to prevent side-load bending on the 16 mm rod.
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 MBLD50X175S FAQ
Because the double-rod design has equal piston area on both sides, push and pull forces are identical: 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a maximum theoretical 180 kgf at 1.0 MPa.
A single-rod cylinder has a larger push force than pull force due to the rod occupying one side. The MBLD50X175S has a rod exiting both ends, making extend and retract forces perfectly equal, and allows you to mount a cam or secondary tool on the rear rod end.
