Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X175S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X175S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø25mm bore and 175mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 206 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X175S
The AirTAC MBLD25X175S is a double-acting, double-rod aluminum mini cylinder with a 25mm bore and 175mm stroke. Because a Ø10mm piston rod exits both end covers, the effective annular area is identical on extend and retract, yielding 206N of force both ways at 0.5 MPa (289N at 0.7MPa). The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic switches to track position. End-of-stroke impact is absorbed by a fixed rubber bumper.
The dual-rod architecture provides inherent anti-rotation stability for a light load, while the rear rod can drive a secondary mechanism or position flag. With an overall length of A + 350mm, you must leave rear-rod clearance. The riveted rolling-packed aluminum barrel and 20um hard-chrome plated carbon-steel rod ensure durable, low-friction operation without position holding—air must remain live to prevent drift.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X175S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X175S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø25 mm |
| Stroke | 175 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 300 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 (Ø25mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 MBLD25X175S Is Used
PCB Stencil Wiping
Drives a wiper blade across solder paste stencils; the twin rods prevent blade yaw while the rear rod triggers a reed sensor to confirm stroke completion at 206N.
Textile Beam Let-Off
Regulates yarn tension on weaving beams. The equal 206N push/pull force maintains consistent tension regardless of direction, with the rear rod mounting a mechanical limit flag.
Chip Tray Ejection
Pushes populated ceramic trays out of a test socket. The 175mm stroke clears the handler, while the fixed rubber bumper softens the ejection stop without bouncing the delicate load.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD25X175S the Right Cylinder?
Stepping down to the 20mm bore drops the both-way force to 132N at 0.5MPa, while stepping up to the 32mm bore raises it to 346N. Unlike the single-rod MBL, this MBLD gives equal push/pull dynamics, and unlike the MBLCD, it uses a fixed rubber bumper rather than adjustable air cushioning. Mounting is limited to Basic, FA flange, or LB foot brackets—no SDB pivot or back-cover options exist. For a drop-in replacement, match the 25mm bore, 175mm stroke, G1/8 port, PT thread, and -S magnet. At 175mm, the 8-16mm rod needs an external guide to prevent bending under offset 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 MBLD25X175S FAQ
Because the double-rod design has equal piston area on both sides, force is identical in both directions: 206N at 0.5 MPa, 289N at 0.7 MPa, and a maximum of 42 kgf at 1.0 MPa.
The MBLD has a rod exiting both ends, giving equal extend/retract force and speed, plus better anti-rotation guidance. The rear rod can mount a cam or position flag. The -S magnet on this unit enables CMSG/DMSG/EMSG sensors, but a plain MBLD cannot hold position without live air.
