Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X175 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 175mm 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 MBLD20X175
The AirTAC MBLD20X175 is a compact, double-acting double-rod aluminum mini cylinder. A single piston drives an Ø8 mm carbon-steel rod out of both end covers, yielding exactly 132 N of force in both extend and retract directions at 0.5 MPa. Because the annulus area is identical on both sides, push and pull speeds match perfectly. This 175 mm stroke suits compact ejection or indexing tasks where a rear rod can simultaneously drive a cam or position flag.
The riveted rolling-packed aluminum barrel and grease-retaining piston seal ensure reliable service within a -20 to +70 °C range. End-of-stroke energy is absorbed by a fixed rubber bumper. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without a physical upgrade. Overall length equals A + 2 x stroke, so rear-rod clearance must be designed into your layout.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 175 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 MBLD20X175 Is Used
PCB Depaneling Saw
Drives a 175 mm stroke circular saw blade to cut PCB panels, using the rear rod end to trip a limit flag confirming full blade extension at 132 N.
Chip Ejector Mechanism
Pushes rejected microchips out of a test socket with 132 N of equal bidirectional force, ensuring smooth retraction without spring-back lag.
Textile Guide Arm
Shifts a yarn guide arm 175 mm across a weaving loom, leveraging the twin rods to prevent the guide from twisting under load.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X175 the Right Cylinder?
If 132 N is insufficient, step up to the MBLD25 bore, which provides 206 N at 0.5 MPa. If you need less force or a smaller footprint, the MBLD20 is the smallest available bore in the series. Because this is a 175 mm stroke on an Ø8 mm rod, external side-load guidance is strongly recommended to prevent rod bending. Unlike the single-rod MBL, the MBLD provides equal force both ways and dual-side anti-rotation. If adjustable air cushioning is required 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. To replace this unit, match the 20 mm bore, 175 mm stroke, G1/8 port, PT thread, and lack of an -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 MBLD20X175 FAQ
Because a rod occupies both sides of the piston, the effective area is identical in both directions. The force is 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum of 27 kgf at 1.0 MPa for both extend and retract strokes.
No, this specific SKU lacks the built-in magnet (no -S code), so it cannot support AirTAC CMSG reed or DMSG/EMSG electronic sensors. You would need the MBLD20X175S variant for solid-state or reed switch position detection.
