Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X300S
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X300S is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 300mm stroke. A rod exits both end covers, so extend and retract force are EQUAL — about 881 N each way at 0.5 MPa. Adjustable air cushion (both ends).

About the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X300S
The AirTAC MBLCD50X300S is a compact double-acting twin-rod mini cylinder featuring an adjustable air cushion at both ends. Because a Ø16mm rod protrudes from each cover, the effective piston area is identical on extend and retract, yielding exactly 881 N of force both ways at 0.5 MPa. The built-in magnet (-S) supports CMSG reed and DMSG/EMSG electronic sensors for mid-stroke position detection. A 300mm stroke suits long-travel indexing and large-format part ejection.
Twin rods provide inherent anti-rotation and let you mount a cam or secondary tool on the rear rod end. The screw-tunable cushions decelerate heavy 180 kgf maximum loads at stroke ends, protecting the riveted aluminum covers better than a fixed rubber bumper. Overall length equals A plus 2x stroke, so you must leave rear-rod clearance. The standard PT port and grease-retaining two-way seal ensure reliable operation up to 800 mm/s.

| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X300S |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 300 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 (Ø50mm, equal both ways)
| Pressure | Extend & retract force |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 MBLCD50X300S Is Used
Printed Circuit Board Conveyor
Drives a 300mm long indexing carriage in a PCB assembly line. The twin rods prevent beam rotation during transfer, while the 881N force handles heavy panel racks.
Large-Format Screen Printer
Shifts a heavy squeegee assembly back and forth. The rear rod end mounts a physical cam to trigger pneumatic valves, eliminating the need for separate actuators.
Packaging Carton Ejector
Ejects filled cartons from a sealing station. The adjustable air cushions absorb the 1233N dynamic load at 0.7MPa at stroke ends, preventing end-cover damage on fast cycles.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X300S the Right Cylinder?
At 0.5 MPa this 50mm bore delivers 881 N both directions. If you need less force, step down to the 40mm bore (528 N); if your payload is heavier, step up to the 63mm bore (1457 N). For long 300mm strokes, side-load and rod bending are real risks—use FA or LB mounts with external guide rails to prevent binding. MBLCD offers Basic, FA, and LB mounting only; there is no SDB pivot or back-cover option.
Choose this MBLCD over the base MBLD when your moving mass demands tunable end-of-stroke deceleration rather than a fixed bumper. The adjustable cushion slows the load but does not lock it; the rod will drift without live air pressure. To replace this unit, match the 50mm bore, 300mm stroke, G1/4 port, PT threads, FA/LB mounting, and 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 MBLCD Aluminum Alloy Mini Cylinder MBLCD50X300S FAQ
Because a rod extends from both ends, the push and pull forces are equal. It delivers 881 N at 0.5 MPa and 1233 N at 0.7 MPa in both directions. The maximum theoretical force is 180 kgf at 1.0 MPa.
Yes, the -S code means a built-in magnet is fitted, allowing you to mount AirTAC CMSG (reed) or DMSG/EMSG (electronic) switches for position detection. The adjustable air cushion at both ends uses a screw to tune end-of-stroke deceleration, protecting the covers on heavy moves; it is not a locking device.
