Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S 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. Adjustable air cushion (both ends).

About the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S
The AirTAC MBLCD63X80S is a compact double-acting double-rod mini cylinder featuring an adjustable air cushion at both ends and a built-in magnet. Because a Ø16 mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding exactly 1457 N of force each way at 0.5 MPa. An 80 mm stroke provides short, high-impact linear motion for heavy payloads.
The screw-tunable cushioning allows you to dial in end-of-stroke deceleration, protecting the riveted aluminum end covers during fast 30-800 mm/s cycles where a fixed rubber bumper would degrade. The rear protruding rod can mount a cam or flag for external signaling while providing inherent anti-rotation resistance. Overall length equals A plus twice the stroke, so rear-rod clearance is mandatory. The -S code equips this PT-threaded unit for CMSG reed or DMSG/EMSG electronic sensor tracking.
Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S Technical Specifications
| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S |
|---|---|
| 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 | 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 MBLCD63X80S Is Used
Stamping Press Feed
Drives a short 80 mm gripper stroke to advance heavy sheet metal into a mechanical press, relying on 1457 N of equal both-way force to push and retract the stock without rotational twist.
Injection Mold Ejector
Uses the twin-rod architecture to eject dense plastic parts from a mold cavity symmetrically, while the adjustable air cushion softens the 2040 N impact at 0.7 MPa to protect the mold face.
Packaging Flap Folder
Folds heavy corrugated carton flaps simultaneously from both sides; the rear rod mounts a physical flag that triggers a DMSG electronic sensor to confirm fold completion before taping.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S the Right Cylinder?
This 63 mm bore generates 1457 N both ways at 0.5 MPa. If your payload is lighter, step down to the 50 mm bore (881 N); if you need more thrust, this is the largest available MBLCD size. Choose MBLCD over the MBLD when your twin-rod cycle speeds require tunable shock absorption rather than a fixed bumper. Mounting is limited to Basic, FA flange, or LB foot—there is no back-cover or SDB pivot option. To hold position without live air, add an external locking device since the cushion only decelerates and does not lock. Replacement requires matching the 63 mm bore, 80 mm stroke, G1/4 port, PT thread, and -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 MBLCD Aluminum Alloy Mini Cylinder MBLCD63X80S FAQ
Because a rod occupies both sides of the piston, extend and retract forces are equal. It outputs 1457 N at 0.5 MPa, 2040 N at 0.7 MPa, and a theoretical maximum of 297 kgf at 1.0 MPa.
The adjustable air cushion uses a needle screw to trap and bleed exhaust air at stroke ends, decelerating heavy loads to protect the end covers. It is strictly a shock absorber, not a lock; the rod will drift if air pressure is removed. The -S magnet allows CMSG, DMSG, or EMSG sensors to track position.
