Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X175S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 175mm 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 MBLD40X175S
The AirTAC MBLD40X175S is a compact double-acting double-rod aluminum mini cylinder engineered to deliver 528 N of thrust and pull at 0.5 MPa. Because a Ø16 mm carbon-steel rod extends from both end covers, the annular piston area is identical on both sides, ensuring the extend and retract forces are perfectly equal. This 175 mm stroke suits automated indexing and transfer tasks requiring symmetrical displacement. The riveted rolling-packed aluminum barrel and grease-retaining two-way piston seal provide lasting durability in tight machinery spaces.
Fitted with a built-in magnet (-S), this model supports AirTAC CMSG reed and DMSG/EMSG electronic sensors for end-of-stroke detection. The rod exits both ends, meaning you can mount the primary workpiece on the front and a position flag or cam on the rear rod. Overall length equals the base body length plus twice the stroke, so you must leave rear clearance. The fixed rubber bumper absorbs end-impact energy, but note this is not an adjustable air cushion (see MBLCD) or a position lock.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 175 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 MBLD40X175S Is Used
PCB Edge Conveyor Routing
Drives a 175 mm stroke routing gate on a PCB conveyor, using the equal 528 N force to cleanly divert boards without asymmetric speed drift.
Textile Loom Takedown Cam
Mounts a takedown cam on the rear rod and the gripper on the front, leveraging the twin-rod anti-rotation property to maintain precise fabric tension.
Semiconductor Wafer Flag
Uses the protruding rear rod to trigger a DMSG electronic sensor, confirming full 175 mm extension for a wafer transfer arm operating at 528 N.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175S the Right Cylinder?
When sizing this 40 mm bore, stepping down to the 32 mm variant yields 346 N at 0.5 MPa, whereas stepping up to the 50 mm bore provides 881 N. Choose this 528 N model when your mechanism requires balanced push/pull dynamics. Unlike the single-rod MBL, this double-rod design prevents rod-side force asymmetry. Mounting is limited to Basic, FA flange, or LB foot; there is no SDB pivot or back-cover option. For replacement, verify the 40 mm bore, 175 mm stroke, G1/4 port, PT thread, and magnet. At 175 mm stroke, the extended twin rods still require an external guide to prevent bending under lateral 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 MBLD40X175S FAQ
The double-rod design provides equal force both ways: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf (1059 N) at 1.0 MPa.
A rod exits both ends, making the extend and retract piston areas equal for matched speed and force. The rear rod can drive a second mechanism or position flag. It uses a fixed rubber bumper, not adjustable cushions.
