Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X80S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X80S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 80mm 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 MBLD63X80S
The AirTAC MBLD63X80S is a compact, double-acting double-rod aluminum mini cylinder engineered to deliver 1457 N of force in both extend and retract directions at 0.5 MPa. Because a carbon-steel rod with 20 µm hard-chrome plating protrudes from both end covers, the annular piston area is identical on each side. This yields perfectly balanced thrust and speed, making the 80 mm stroke highly effective for driving heavy mid-stroke loads without deceleration lag. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal ensure long-term lubrication in tight, high-cycle assemblies.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSG (reed), DMSG, and EMSG (electronic solid-state) position switches for precise end-of-stroke confirmation. A defining mechanical advantage of this twin-rod layout is dual-side guidance: you can mount a heavy workpiece on the front M14x1.5 rod end while using the rear protruding rod to drive a secondary mechanism or trigger a physical limit cam. Impact at the 80 mm stroke ends is absorbed by a fixed rubber bumper. Note that this bumper softens end-of-travel shock but does not lock the rod; the cylinder will drift without live air pressure, so an external holding device is required for fail-safe positioning.

| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X80S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 80 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 MBLD63X80S Is Used
Injection Mold Ejection
Drives a synchronized ejection plate in a 63 mm bore injection molding machine, using the 1457 N equal both-way force to push parts out cleanly and retract the plate without rotational twist.
Printed Circuit Board Stacking
Aligns and stacks heavy PCB panels in a conveyorized assembly line, leveraging the twin 16 mm rods to prevent binding and maintain parallelism across the 80 mm stroke.
Pneumatic Press Cam Trigger
Mounts the primary stamping tool on the front rod while the rear rod protrudes to physically trigger a mechanical limit cam, sequencing a high-force 2040 N pressing operation.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X80S the Right Cylinder?
Stepping down in bore size, the 50 mm variant provides 881 N at 0.5 MPa, which may suffice for lighter pick-and-place tasks. If your pneumatic system demands even greater thrust, note that 63 mm is the largest bore in the MBL mini cylinder family, so exceeding 2040 N at 0.7 MPa requires stepping up to a larger ISO 15552 profile cylinder. Unlike the single-rod MBL series, this MBLD guarantees equal push and pull forces. If your application experiences severe kinetic energy at the end of the 80 mm stroke, consider the MBLCD variant, which replaces the fixed rubber bumper with an adjustable air cushion. Mounting is limited to Basic, FA (flange), or LB (foot) brackets; there is no SDB pivot or back-cover (CA/U) option available for the double-rod design. When ordering a replacement, verify the 63 mm bore, 80 mm stroke, G1/4 port, default PT thread, and the presence of the -S magnet.
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 MBLD63X80S FAQ
Because the double-rod design has equal annular piston area on both sides, the push and pull forces are identical: 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a maximum theoretical force of 297 kgf at 1.0 MPa.
A single-rod cylinder has unequal push/pull forces, whereas the MBLD twin-rod layout makes them perfectly equal and allows you to mount a secondary cam or guide on the rear rod. The -S suffix indicates a built-in magnet for use with AirTAC CMSG (reed) and DMSG/EMSG (electronic) sensor switches; without -S, no sensor can be fitted.
