Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X75 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 MBLD20X75
The AirTAC MBLD20X75 is a compact double-acting double-rod aluminum mini cylinder. A single piston drives an Ø8mm carbon-steel rod out of both end covers, yielding equal annulus areas. This means push and pull forces are identical, providing 132N each way at 0.5MPa and 185N at 0.7MPa. The 75mm stroke is well-suited for short-transfer and indexing tasks where symmetrical motion is critical.
Because a rod protrudes from the rear, you can mount a position flag or cam on the opposite end to trigger an external limit switch. The riveted rolling-packed aluminum barrel and grease-retaining piston seal keep the body light for tight spaces. This base SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG sensors. End-of-travel impact is absorbed by a fixed rubber bumper, which is not a lock—rod drift occurs without live air.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75 |
|---|---|
| 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 MBLD20X75 Is Used
PCB Edge Guide
Drives a 132N lateral indexing pin on a PCB conveyor to align panels equally in both extend and retract strokes without rotational bias.
Pick-and-Place Cam
Uses the rear Ø8mm rod end to physically trip an external mechanical limit switch on a small pick-and-place gantry, eliminating the need for an electronic sensor.
Film Edge Tracking
Maintains equal tension on a packaging film web guide, using the twin-rod anti-rotation property to prevent binding during 75mm travel.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X75 the Right Cylinder?
Stepping down to a smaller bore is not an option as 20mm is the smallest available MBLD size. If you need more force, the next size up is the 25mm bore, which provides 206N at 0.5MPa. Consider the single-rod MBL20X75 if your application only requires standard push force and you do not need rear-rod mounting or equal bidirectional thrust. If adjustable air cushioning is required to soften end impacts, choose the MBLCD20X75 variant instead of this fixed-bumper model.
Mounting is limited to Basic, FA flange, or LB foot brackets; the double-rod design does not support SDB pivot or back-cover options. The standard PT (tapered) thread matches the G1/8 port. Remember that the overall length equals A plus 2 times the stroke, so you must leave rear-rod clearance in your layout. For exact envelope dimensions, confirm from the datasheet.
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 MBLD20X75 FAQ
Because a rod exits both ends, the effective piston area is identical in both directions. The force is equal both ways: 132N at 0.5MPa, 185N at 0.7MPa, and a maximum theoretical output of 27kgf at 1.0MPa.
No. This specific MBLD20X75 SKU lacks the built-in -S magnet. To use AirTAC CMSG (reed), DMSG, or EMSG (solid-state) switches for position detection, you must order the MBLD20X75S variant instead.
