Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X75
The AirTAC Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X75 is a genuine double-acting double-rod aluminum-barrel mini cylinder with a Ø50mm bore and 75mm 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 MBLCD50X75
The AirTAC MBLCD50X75 is a compact double-acting double-rod mini cylinder featuring an adjustable air cushion at both ends. Because a Ø16 mm rod exits both covers, the annulus area is identical on each side, yielding exactly 881 N of force at 0.5 MPa in both extend and retract directions. The 75 mm stroke is ideal for mid-range transfer tasks requiring high bilateral thrust.
Twin rods provide inherent anti-rotation resistance and allow a cam or secondary tool to mount on the rear rod extension. The riveted aluminum barrel houses a grease-retaining piston seal, while the carbon-steel rod features 20 µm hard-chrome plating. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.
Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X75 Technical Specifications
| Model | Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X75 |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder (double rod) |
| Bore size | Ø50 mm |
| Stroke | 75 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 MBLCD50X75 Is Used
Printed Circuit Board Loader
Drives a 75 mm dual-sided pusher arm to transfer PCB panels into an inspection station, using the equal 881 N thrust to maintain balanced pressure without rotating the tooling.
Textile Loom Guide Mechanism
Actuates a traversing yarn guide where the rear rod simultaneously operates a mechanical flag, while the adjustable cushion absorbs the kinetic energy of rapid reversals.
Packaging Flap Folder
Folds cardboard carton flaps simultaneously from both sides, leveraging the twin-rod anti-rotation property to keep the folding blades perfectly aligned under 1233 N at 0.7 MPa.
Is the Airtac MBLCD Aluminum Alloy Mini Cylinder MBLCD50X75 the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 881 N each way. If your payload is lighter, the 40 mm bore provides 528 N, whereas the larger 63 mm bore yields 1457 N for heavier loads. Choose this MBLCD over the base MBLD when your twin-rod cycle speeds require screw-tunable end-of-stroke deceleration to prevent end-cover damage. The cushion only dampens impact near stroke ends; it does not lock the rod, so external holding devices are needed if mid-stroke positioning must be maintained without live air.
Mounting is limited to Basic, FA flange, or LB foot options; no back-cover or SDB pivot brackets exist for this series. Overall length equals the base dimension plus twice the stroke, meaning a rod protrudes from the rear, so you must leave appropriate clearance. Replacement requires matching the 50 mm bore, 75 mm stroke, G1/4 port, PT thread, and no 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 MBLCD50X75 FAQ
Because the rod exits both ends, push and pull forces are equal: 881 N at 0.5 MPa, 1233 N at 0.7 MPa, and a theoretical maximum of 180 kgf at 1.0 MPa. The adjustable air cushion only decelerates the piston near the end covers; it is not a lock, so the rod will drift if air pressure is removed.
No. This MBLCD50X75 SKU does not have a built-in magnet (no -S suffix), so it cannot trigger AirTAC CMSG reed or DMSG/EMSG electronic sensors. If you require position detection, select the MBLCD50X75S variant. The adjustable air cushion at both ends is screw-tunable to protect the end covers on heavier twin-rod moves.
