Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100
The AirTAC MBLD Dual Axis Type Mini Cylinder MBLD20X100 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø20mm bore and 100mm 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 MBLD20X100
The AirTAC MBLD20X100 is a double-acting, double-rod aluminum mini cylinder featuring a 20mm bore and 100mm stroke. Because a carbon-steel rod protrudes from both end covers, the annulus area is identical on both sides, yielding perfectly equal force and speed in both directions. You get 132 N of thrust and retraction at 0.5 MPa, and 185 N at 0.7 MPa.
This through-rod geometry allows you to mount the workpiece on one end and a position flag or cam on the rear rod, providing dual-side guidance that resists twisting. The 100mm travel suits compact indexing tasks, but because overall length equals A plus twice the stroke, you must leave rear-rod clearance. It uses a fixed rubber bumper, not an adjustable cushion, and this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100 Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø20 mm |
| Stroke | 100 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 MBLD20X100 Is Used
PCB Shuttle Conveyor
Drives a 100mm shuttle stroke on a PCB assembly line, using the twin rods to keep the light carrier pallet guided against rotation during transfer.
Limit Cam Trigger
Uses the rear protruding rod to actuate a mechanical limit cam on a semiconductor sorting station, keeping the primary front rod dedicated to the pick-and-place motion.
Label Applicator Press
Tamps labels onto small cartons with a precise 132N force at 0.5 MPa, where the equal both-way speed ensures consistent dwell and rapid release.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD20X100 the Right Cylinder?
If you need slightly less force, stepping down is not possible as 20mm is the smallest available bore. Stepping up to the 32mm bore yields 346 N at 0.5 MPa, which is a significant jump for heavier mechanisms. Unlike the single-rod MBL, this MBLD ensures equal push and pull dynamics, while the MBLCD variant offers adjustable air cushions if you need softer end-of-stroke deceleration. Mounting is strictly limited to Basic, FA flange, or LB foot styles; there is no back-cover or SDB pivot option. Ensure your replacement matches the G1/8 port, PT thread, and 100mm stroke. Without live air pressure, the rod will drift, so use an external lock for holding.
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 MBLD20X100 FAQ
Because the rod occupies both sides of the piston, the force is identical in both directions: 132 N at 0.5 MPa, 185 N at 0.7 MPa, and a maximum theoretical 27 kgf at 1.0 MPa.
A double-rod cylinder provides equal extend and retract forces and speeds due to the matching annulus areas. It also allows you to mount a secondary tool or position flag on the rear rod. Note that this MBLD20X100 SKU has no built-in magnet, so it cannot be fitted with CMSG, DMSG, or EMSG sensors.
