Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 75mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 1458 N each way at 0.5 MPa. Fixed rubber bumper.

About the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75S
The AirTAC MBLD63X75S is a double-acting, double-rod aluminum mini cylinder engineered for applications demanding equal force in both directions. Because a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating exits both end covers, the effective piston area is identical on extend and retract, yielding a symmetrical 1457 N of thrust at 0.5 MPa. The built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic switches to track position. A 75 mm stroke provides moderate travel for heavier jig actuation.
This model features a riveted rolling-packed aluminum barrel and a fixed rubber bumper to soften end-of-stroke impact. The twin-rod architecture provides inherent anti-rotation resistance and allows a secondary cam or position flag to be mounted on the rear rod protrusion. Keep in mind the overall length equals the base body plus twice the stroke, so rear clearance is required.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 75 mm |
| Acting type | Double acting, double rod |
| Port size | G1/4 |
| Rod thread | M14×1.5 |
| 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 (Ø63mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 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 MBLD63X75S Is Used
Injection Mold Ejection
Drives a 75 mm ejection pin plate on the front rod while the rear rod actuates a return cam, utilizing the equal 1457 N force to reliably strip dense plastic parts from a mold cavity.
PCB Conveyor Diverting
Mounts a diverter blade on one end and a position flag on the opposing rod end to trigger a DMSG sensor, ensuring symmetrical speed and 2040 N force at 0.7 MPa for shifting heavy assembly pallets.
Stainless Panel Bending
Uses the twin-rod anti-rotation property to press a 75 mm flange bend in sheet metal, where the matched extend and retract forces prevent workpiece twisting during the forming cycle.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X75S the Right Cylinder?
Selecting the MBLD63X75S gives you the maximum standard thrust in this mini series. If 1457 N at 0.5 MPa is excessive, stepping down to the 50 mm bore drops the output to 881 N. As the largest bore, there is no larger standard size. The G1/4 port matches the high air flow required for this bore. Mounting is limited to Basic, FA flange, or LB foot; no SDB pivot or back-cover options exist for the double-rod type.
When replacing or specifying, verify the 75 mm stroke, PT thread, and FA/LB mounting. The fixed rubber bumper absorbs impact but does not lock the rod; without live air pressure, the cylinder drifts. For applications needing adjustable end-cushioning to dissipate the 297 kgf maximum kinetic energy, specify the MBLCD variant instead.
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 MBLD63X75S FAQ
Because the double-rod design has equal annulus areas on both sides, the push and pull forces are identical: 1457 N at 0.5 MPa and 2040 N at 0.7 MPa. The maximum theoretical force is 297 kgf at 1.0 MPa.
The twin rods provide equal force and speed both ways, plus better resistance to side-load twisting. The -S code means a magnet is built in, allowing you to attach CMSG reed or DMSG/EMSG electronic switches for position detection. A plain non-S SKU cannot take a sensor.
