Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X175 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 MBLD40X175
The AirTAC MBLD40X175 is a double-acting, double-rod aluminum mini cylinder featuring a 40mm bore and 175mm stroke. Because a carbon-steel rod protrudes from both end covers, the annulus piston area is identical on extend and retract. This yields equal force and speed in both directions, providing 528N at 0.5 MPa and 739N at 0.7 MPa. The 175mm stroke is well-suited for mid-range indexing or dual-action ejection tasks. It uses a fixed rubber bumper to soften end-of-travel impact.
This configuration uses a PT port thread and lacks the -S magnet suffix, meaning no position sensor can be fitted. A key advantage of the twin-rod layout is dual-side guidance: you can mount the primary workpiece on the front rod and a position flag or cam on the rear rod. Keep in mind the overall length equals the base body plus twice the stroke, so you must leave rear-rod clearance in your machine layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175 |
|---|---|
| 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 MBLD40X175 Is Used
PCB Conveyor Stopper
Uses the 528N both-way force to halt 175mm wide PCB panels on an assembly line, while the rear rod drives a physical limit flag to time the downstream pick-and-place machine.
Textile Loom Tensioner
Balances yarn tension equally on extend and retract without speed variation, leveraging the twin-rod anti-rotation property to keep the guide arm perfectly aligned.
Chip Tray Ejector
Pushes loaded semiconductor trays out of a test socket with equal push and pull force, using the rear protruding rod to actuate a secondary mechanical interlock.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X175 the Right Cylinder?
When sizing this 40mm bore model, stepping down to the 32mm variant drops the both-way force to 346N at 0.5 MPa, while stepping up to the 50mm bore increases it to 881N. If your application needs adjustable air cushioning rather than fixed rubber bumpers, choose the MBLCD variant. For single-direction tasks where equal force is unnecessary, the single-rod MBL saves space.
Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option. This plain MBLD40X175 cannot hold position without live air and will drift if pressure drops. To replace this unit, match the 40mm bore, 175mm stroke, G1/4 port, PT thread, and confirm no magnet is required.
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 MBLD40X175 FAQ
Because the double-rod design has equal piston area on both sides, output force is identical in extend and retract. It generates 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum theoretical 108kgf at 1.0 MPa.
No. This specific SKU lacks the -S code, meaning no built-in magnet is fitted. To use CMSG reed or DMSG/EMSG electronic switches, you must select the MBLD40X175S version. The double-rod design also means a rod exits both ends, requiring rear clearance.
