Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 25mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 1458 N each way at 0.5 MPa. Adjustable air cushion (both ends).

About the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25
The AirTAC MBLCD63X25 is a compact double-acting twin-rod mini cylinder featuring an adjustable air cushion at both ends. Because a Ø16 mm rod exits both covers, the effective piston area is identical on extend and retract, yielding equal force and speed in both directions at 1457 N each way at 0.5 MPa.
This 25 mm short stroke is ideal for high-force gripping or rapid pressing in confined spaces. The riveted aluminum barrel and grease-retaining two-way seal keep the unit light, while the 20 µm hard-chrome carbon-steel rods resist wear and provide dual-side guidance to prevent twist. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors.
Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25 Technical Specifications
| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 25 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 | Adjustable air cushion (both ends) |
| 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 MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25 Is Used
Injection Mold Ejection
Provides 1457 N of equal both-way force to eject plastic parts from molds, using the twin rods to maintain strict anti-rotation alignment and the cushion to silently absorb the abrupt 25 mm end stop.
Pneumatic riveting press
Delivers rapid 25 mm high-impact strikes for rivet setting, where the adjustable air cushion slows the heavy twin-rod mass just before impact to prevent end-cover fracture.
Dual-Side PCB clamping
Secures delicate printed circuit boards during automated soldering by clamping from both edges simultaneously, using the equal extend and retract speeds to prevent board warping.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25 the Right Cylinder?
For tasks needing less force, the 50 mm bore neighbor provides 881 N at 0.5 MPa; if your application requires even heavier thrust, this 63 mm bore is the largest available in the series, delivering a maximum theoretical 297 kgf at 1.0 MPa. Choose this MBLCD over the MBLD variant when moving heavier payloads at speed, as the screw-tunable air cushion decelerates the end-of-stroke impact to protect the end covers rather than relying on a fixed rubber bumper.
Mounting is limited to Basic, FA flange, or LB foot brackets; no back-cover or SDB pivot options exist. Since this SKU is shipped without the -S magnet, position feedback requires an external mechanical switch. A plain cylinder cannot hold position without live air pressure—the cushion only decelerates near the stroke ends and does not lock the rod. The PT tapered port threads and M14x1.5 rod-end threads must be matched exactly when sourcing replacement seals or rod accessories.
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 MBLCD Aluminum Alloy Mini Cylinder MBLCD63X25 FAQ
Because the double-rod design has equal annular areas on both sides, push and pull forces are identical: 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum theoretical 297 kgf at 1.0 MPa. This specific SKU does not have a built-in magnet, so it cannot support CMSG reed or DMSG/EMSG electronic sensors.
The adjustable air cushion uses needle screws to tune end-of-stroke deceleration, which is critical for protecting the end covers when moving heavier twin-rod payloads at high speeds. Unlike a fixed rubber bumper that wears out and bottom-outs hard, this cushion actively decelerates the load, though it does not lock or hold position without live air.
