Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD40X15S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 MBLD40X15S
The AirTAC MBLD40X15S is a double-acting, double-rod aluminum mini cylinder engineered for equal force in both directions. Because a Ø16 mm rod protrudes from both end covers, the annular piston area is identical on extend and retract, yielding 528 N at 0.5 MPa both ways. The 15 mm stroke is ideal for high-cycle short-index motions where space is tight.
This S-suffix configuration includes a built-in magnet for CMSG (reed), DMSG, or EMSG (solid-state) position sensing. It features a riveted rolling-packed aluminum barrel and a 20 µm hard-chrome plated carbon-steel rod. End-of-travel impact is absorbed by fixed rubber bumpers, while the rear rod end can simultaneously drive a secondary mechanism or position flag.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø40 mm |
| Stroke | 15 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 MBLD40X15S Is Used
PCB Edge-Guide Pop-Up
Uses the 528 N equal both-way force to pop a 15 mm guide pin up and retract it flush on a PCB conveyor without drift.
Dual-Side Label Wipe
Mounts a wiper blade on the front rod and a position flag on the rear rod to synchronously wipe and verify labels on a 15 mm stroke.
Connector Seating Press
Delivers 739 N at 0.7 MPa to evenly seat micro-connectors in an electronics assembly jig using its twin-rod anti-rotation stability.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD40X15S the Right Cylinder?
For lower force needs, the MBLD32 bore provides 346 N at 0.5 MPa, while stepping up to the MBLD50 yields 881 N for heavier loads. Choose the MBLCD variant if your application requires adjustable air cushioning instead of the standard fixed rubber bumper. Mounting is limited to Basic, FA flange, or LB foot brackets; MBLD lacks back-cover or SDB pivot options. To hold position without live air, install an external lock, as the bumper is not a locking device. Replacement requires matching the 40 mm bore, 15 mm stroke, G1/4 port, PT thread, and S magnet.
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 MBLD40X15S FAQ
The double-rod design provides equal force both ways: 528 N at 0.5 MPa and 739 N at 0.7 MPa for both extend and retract. The theoretical maximum is 108 kgf at 1.0 MPa.
The -S suffix indicates a built-in magnet for rod position detection. It allows you to mount AirTAC CMSG (reed) or DMSG and EMSG (electronic/solid-state) sensor switches along the barrel. A SKU without -S cannot accept a sensor.
