Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X250
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X250 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 250mm 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 MBLCD63X250
The AirTAC MBLCD63X250 is a double-acting, twin-rod mini cylinder featuring a 63mm bore and a 250mm stroke. Because a carbon-steel rod with 20μm hard-chrome plating extends from both end covers, the effective piston area is identical on both sides, yielding equal push and pull forces of 1457 N at 0.5 MPa. This symmetry is ideal for mechanisms requiring consistent bidirectional dynamics. It uses a G1/4 port and an M14x1.5 rod-end thread.
This model incorporates a screw-tunable adjustable air cushion at both ends, decelerating heavy 297 kgf-class loads before impact to prevent end-cover damage during fast 250mm cycles. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The riveted aluminum barrel keeps the body compact while the twin-rod architecture inherently resists rotation, allowing a cam or flag to be mounted on the rear rod.

|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 250 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 MBLCD63X250 Is Used
Injection Mold Platen Transfer
Uses the 2040 N both-way force at 0.7 MPa to push and pull heavy mold bases out of a press, relying on the adjustable air cushion to softly stop the 250mm travel without shocking the tooling.
Textile Calender Guide
Drives a dual-side calender roller adjustment mechanism where the twin rods prevent rotational drift, ensuring parallel fabric tracking across a 250mm span.
Woodworking Panel Lift
Lifts and lowers heavy MDF panels using equal 1457 N force in both directions, with the rear rod end actuating a mechanical cam to trigger a downstream crosscut saw.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X250 the Right Cylinder?
At 250mm stroke, this 63mm bore generates 1457 N both ways. If your mechanism is overpowered, stepping down to the 50mm bore drops the both-way force to 881 N at 0.5 MPa while retaining the same 250mm travel. As the largest available MBLCD size, there is no larger bore to step up to for higher force. For applications needing exact mid-stroke position feedback, you must select an -S magnet variant, as this base configuration cannot fit a reed or solid-state switch.
When replacing this cylinder, match the 63mm bore, 250mm stroke, G1/4 port, PT thread, and basic mounting. Mounting is limited to Basic, FA flange, or LB foot; no SDB pivot or back-cover options exist. Because the overall length equals A + 2x stroke, you must leave rear-rod clearance for the protruding shaft. Furthermore, at 250mm travel, the twin rods are susceptible to bending under side loads—use external linear bearings to manage off-center forces and prevent binding. Remember, the adjustable air cushion only decelerates the load near the end caps; it does not lock position, so external holding devices are required if power is lost.
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 MBLCD63X250 FAQ
Because the rod exits both ends, force is identical in both directions: 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 include a built-in magnet, so it cannot be used with AirTAC CMSG (reed), DMSG, or EMSG (solid-state) position sensors.
The MBLCD uses screw-tunable adjustable air cushions at both ends to decelerate heavy twin-rod loads over the 250mm stroke, preventing end-cover damage that a fixed rubber bumper cannot absorb at high speeds. The cushion only slows the load near the end of travel; it does not lock the rod, so an external device is needed for position holding.
