Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X125S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X125S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 125mm 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 MBLD63X125S
The AirTAC MBLD63X125S is a double-acting, double-rod aluminum mini cylinder engineered for tasks requiring symmetrical motion. Because a Ø16 mm carbon-steel rod protrudes from both end covers, the effective piston area is identical on extend and retract. This yields an equal 1457 N of force in both directions at 0.5 MPa, preventing the speed and power mismatch seen in single-rod units. The 125 mm stroke suits mid-length indexing, and the built-in magnet (-S) allows CMSG reed or DMSG/EMSG electronic sensors to track rod position.
A defining mechanical advantage here is dual-side actuation: you mount the primary workpiece on the front rod and use the rear protrusion for a position flag, cam, or secondary mechanism. The riveted rolling-packed aluminum barrel keeps the body compact for its 63 mm bore, while the fixed rubber bumper absorbs end-of-travel impact. Remember that overall length equals the base dimension plus twice the stroke, so you must leave physical clearance for the rear rod. This base MBLD uses a fixed rubber bumper; for adjustable air cushioning, you would step up to the MBLCD variant.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X125S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X125S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 125 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 MBLD63X125S Is Used
Stamping Press Ejection
Uses the 2040 N available at 0.7 MPa to knock stamped metal blanks out of a die, using the rear rod to simultaneously trigger a mechanical proximity flag for the conveyor.
PCB Router Z-Axis
Drives a spindle carriage up and down with equal 1457 N force both ways, ensuring consistent plunge and retract speeds without requiring a heavier ISO 15552 cylinder.
Glass Edge Seaming
Synchronizes a dual-side clamping jaw on an automated glass seaming line, leveraging the twin-rod anti-rotation properties to keep the 125 mm stroke perfectly parallel.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X125S the Right Cylinder?
When sizing this 63 mm bore, step down to the 50 mm model if you need less power—it yields 881 N at 0.5 MPa. Stepping up is not possible as 63 mm is the largest MBLD bore. Mounting is limited to Basic, FA flange, or LB foot brackets; there is no back-cover or SDB pivot option for the double-rod series. The Ø16 rod uses an M14x1.5 end thread and G1/4 ports with PT tapered threading. Note that a plain MBLD does not hold position without live air—the rod drifts if pressure drops, so fit an external locking device for fail-safe holding. If your cycle rate is high and impact shock is a concern, switch to the MBLCD for adjustable cushioning.
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 MBLD63X125S FAQ
Because a rod occupies both sides of the piston, the annulus area is equal both ways. The MBLD63X125S delivers 1457 N at 0.5 MPa and 2040 N at 0.7 MPa in BOTH extend and retract directions. The theoretical maximum pull force is 297 kgf at 1.0 MPa.
The double-rod design allows you to mount a workpiece on one end and a cam, guide, or position flag on the rear protruding rod, improving anti-rotation stability. The -S code means a built-in magnet is fitted, allowing AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches to detect rod position.
