Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75S
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X75S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 75mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 132 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75S
The AirTAC MBLD20X75S is a compact double-acting double-rod aluminum mini cylinder featuring a 20mm bore and 75mm stroke. Because a rod exits both end covers, the annulus piston area is identical on extend and retract, yielding exactly 132 N of force each way at 0.5 MPa. This 75mm travel is well-suited for precise indexing and light-duty positioning where symmetry is required.
This S-coded SKU includes a built-in magnet for position sensing via CMSG reed or DMSG/EMSG electronic switches. The riveted rolling-packed aluminum barrel and 20 um hard-chrome plated carbon-steel rod provide durability in tight spaces. It uses a fixed rubber bumper to soften end-of-travel impact, and the protruding rear rod can drive a secondary mechanism or position flag while aiding anti-rotation.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 75 mm |
| Acting type | Double acting, double rod |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 (Ø20mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 MBLD20X75S Is Used
PCB Stencil Wiping
Drives a dual-sided squeegee blade on a solder paste printer, using the 132 N both-way force and rear rod to trigger a pneumatic flag confirming stroke completion.
Chip Ejector Mechanism
Ejects machined silicon wafers from a micro-milling fixture, utilizing the 75mm travel and twin-rod anti-rotation to prevent delicate part scraping.
Textile Guide Flag
Pivots a yarn tensioning guide in a loom, mounting the cam on the rear rod end to actuate a mechanical stop while maintaining compact 20mm bore dimensions.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75S the Right Cylinder?
For 75mm travel, stepping down to the 20mm bore's shorter standard strokes (like 60mm) reduces cycle time, while stepping up to a 25mm bore increases your both-way force to 206 N at 0.5 MPa if 132 N is insufficient. Unlike the single-rod MBL which offers higher push force, the MBLD ensures equal push/pull dynamics. If you need adjustable air cushioning instead of the fixed rubber bumper, select the MBLCD variant. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no SDB pivot or back-cover option. Replacement requires matching the 20mm bore, 75mm stroke, G1/8 port, PT thread, and the -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 MBLD20X75S FAQ
The MBLD20X75S provides equal force in both directions due to the double-rod design: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa.
The twin rods provide equal extend/retract forces and speeds, while allowing you to mount a cam or position flag on the rear rod. The -S magnet enables tracking via CMSG reed or DMSG/EMSG electronic sensors, which a non-S SKU cannot accept.
