Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X20S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X20S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø32mm bore and 20mm 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 MBLD32X20S
The AirTAC MBLD32X20S is a double-acting, double-rod aluminum mini cylinder with a 32 mm bore and 20 mm stroke. Because a Ø12 mm carbon-steel rod exits both end covers, the annular piston area is identical on both sides, yielding equal 346 N force at 0.5 MPa for both extend and retract strokes. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track position. With a short 20 mm stroke, overall length is kept to a minimum, making it ideal for tight, high-cycle machinery.
This model features a riveted rolling-packed aluminum barrel and a fixed rubber bumper at each end to soften impact. The twin-rod architecture provides inherent anti-rotation guidance, letting you mount a workpiece on the front rod and a position flag or cam on the rear rod. Note that the rear rod protrudes and requires clearance in your layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X20S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X20S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø32 mm |
| Stroke | 20 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 MBLD32X20S Is Used
PCB Depaneling Saw Clamp
Secures populated PCB panels against a routing saw blade. The 346 N equal both-way force holds firmly without shifting, while the 20 mm stroke closes the clamp rapidly.
IC Tray Pick-and-Place
Drives a dual-sided vacuum gripper for transferring semiconductor trays. The twin rods prevent sucker rotation during vertical placement, and the -S magnet confirms stroke end.
Label Applicator Tamp Head
Tamps adhesive labels onto cartons. The rear protruding rod mounts an external mechanical flag to trigger a glue valve, utilizing the compact 20 mm stroke for high-speed cycling.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD32X20S the Right Cylinder?
For a 32 mm bore, the 346 N (0.5 MPa) output suits moderate clamping and ejection tasks. If you need less force, step down to the 25 mm bore (206 N); if your mechanism requires more thrust, step up to the 40 mm bore (528 N). Keep in mind the MBLD has no back-cover or SDB pivot bracket options—mounting is limited to Basic, FA flange, or LB foot. If your application demands adjustable end-cushioning rather than the fixed rubber bumper, consider the MBLCD variant. When ordering a replacement, verify the 32 mm bore, 20 mm stroke, G1/8 PT port, and the -S magnet requirement.
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 MBLD32X20S FAQ
Because the MBLD32X20S is a double-rod cylinder, the rod occupies both sides of the piston, making the effective area equal in both directions. The force is 346 N at 0.5 MPa and 484 N at 0.7 MPa for both extend and retract. The theoretical maximum at 1.0 MPa is 71 kgf.
The -S code indicates a built-in piston magnet. It allows you to mount AirTAC CMSG reed switches or DMSG/EMSG electronic solid-state sensors directly to the cylinder body to detect end-of-stroke positions. A model without the -S code cannot accept these sensors.
