Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X20S
The AirTAC Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X20S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø63mm bore and 20mm 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 MBLD63X20S
The AirTAC MBLD63X20S is a double-acting, double-rod aluminum mini cylinder engineered for compact setups needing high force and bidirectional symmetry. A single piston drives a Ø16 mm carbon-steel rod out of both end covers, yielding exactly 1457 N of force at 0.5 MPa on both extend and retract strokes. The 20 mm stroke is ideal for high-force, short-travel operations like pressing or stamping. Because the rod occupies both sides of the piston, the annulus area is identical in each direction, ensuring equal push and pull dynamics without pressure compensation.
This configuration includes a built-in magnet (the -S code) for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic) switches. The riveted rolling-packed aluminum barrel and 20 µm hard-chrome plating protect against wear, while the fixed rubber bumper softens end-of-travel impacts. Note that the rear rod protrudes and requires clearance; overall length equals A plus twice the stroke. The bumper is not a locking mechanism, so an external device is required to hold a load without live air pressure.
Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X20S Technical Specifications
| Model | Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X20S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø63 mm |
| Stroke | 20 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 MBLD63X20S Is Used
Terminal Crimping Press
Delivers 1457 N of equal force on both the extend and retract strokes to crimp wire terminals, using the short 20 mm travel for rapid, high-impact stamping in electrical harness manufacturing.
PCB Shuttle Transfer
Uses the twin-rod symmetry to push and pull a populated PCB panel between inspection stages, mounting the drive on one rod end and a position flag on the rear rod to trigger sensors.
Pneumatic Rivet Squeezer
Applies up to 297 kgf of clamping force to set rivets on aluminum frames, relying on the compact riveted body to fit within tight jig clearances while maintaining anti-rotation guidance.
Is the Airtac MBLD Dual Axis Type Mini Cylinder MBLD63X20S the Right Cylinder?
To size this cylinder correctly, consider stepping down to the 50 mm bore if your application requires less than 881 N at 0.5 MPa, or stepping up is not an option as 63 mm is the largest available MBLD bore. The fixed rubber bumper suits moderate impact speeds, but if your cycle rate causes severe end-impact, the MBLCD variant offers adjustable air cushioning. Mounting is limited to Basic, FA (flange), or LB (foot) brackets; the MBLD series does not support SDB pivot or back-cover mounts. For a direct replacement, match the 63 mm bore, 20 mm stroke, G1/4 port, PT thread, and the -S magnet. Even with twin rods, the 20 mm stroke on a 63 mm body is highly rigid, but always verify external guidance for heavy off-center loads.
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 MBLD63X20S FAQ
The double-rod design means force is equal in both directions because the rod occupies both sides of the piston. It delivers 1457 N at 0.5 MPa and 2040 N at 0.7 MPa, with a theoretical maximum of 297 kgf at 1.0 MPa.
A rod exits both ends, allowing you to mount the workpiece on one side and a cam or position flag on the other for anti-rotation guidance. The -S code indicates a built-in magnet for use with AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches to detect rod position.
