Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X250S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X250S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø32mm bore and 250mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 346 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X250S
The AirTAC MBLD32X250S is a double-acting, double-rod aluminum mini cylinder featuring a 32mm bore and 250mm stroke. Because a Ø12mm carbon-steel rod with 20μm hard-chrome plating protrudes from both end covers, the annulus piston area is identical on both sides. This yields equal force and speed in both directions, generating 346N at 0.5 MPa (484N at 0.7 MPa) on extend and retract. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track position.
This 250mm stroke suits extended traversing or dual-zone actuation. The riveted rolling-packed aluminum barrel keeps the body compact, while the fixed rubber bumper softens end-of-travel impact. Since overall length equals A + 2 x stroke, the rear rod requires substantial clearance. You can mount a workpiece on one end and a position flag or cam on the opposite rod end for synchronized secondary control.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X250S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø32 mm |
| Stroke | 250 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 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 (Ø32mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 MBLD32X250S Is Used
PCB Edge Conveyor Transfer
Drives a 250mm transfer arm in a PCB assembly line, using the equal 346N both-way force to push and reliably retract populated boards without speed variation.
Semiconductor Wafer Cassette Load
Extends a 250mm reach into a wafer processing tool, with a DMSG electronic sensor on the -S magnet confirming full extension before the robotic picker engages.
Textile Loom Tensioner
Uses the protruding rear rod to mount a mechanical tension flag, maintaining balanced 484N bidirectional tension on fabric guide rails during high-speed weaving.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X250S the Right Cylinder?
For sizing flexibility, stepping down to the 25mm bore yields 206N at 0.5 MPa, while stepping up to the 40mm bore provides 528N at 0.5 MPa. Choose the MBLD double-rod over the single-rod MBL when your mechanism requires equal push/pull dynamics or anti-rotation guidance. If your application experiences heavy end-impact at this 250mm stroke, consider the MBLCD variant, which features adjustable air cushions instead of the fixed rubber bumper found here.
Mounting is limited to Basic, FA flange, or LB foot brackets; MBLD has no back-cover or SDB pivot options. At 250mm, the 12mm rod is highly susceptible to bending under lateral loads, so an external guide rail is mandatory to prevent premature seal wear. Note that this plain PT-threaded cylinder does not hold position without continuous live air. Replacement requires matching the 32mm bore, 250mm stroke, G1/8 port, PT thread, and magnet option.
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 MBLD32X250S FAQ
Because the double-rod design has equal piston annulus area on both sides, output force is identical for extend and retract. It provides 346N at 0.5 MPa, 484N at 0.7 MPa, and a maximum theoretical 71 kgf at 1.0 MPa.
A rod exits both end covers, meaning the rear rod protrudes and requires clearance. This equalizes force and speed in both directions and allows a cam or position flag to be mounted on the rear rod for secondary mechanism synchronization, unlike a single-rod MBL cylinder.
