About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80CA
The AirTAC MBLC50X80CA is a double-acting aluminum mini cylinder featuring a 50 mm bore and an 80 mm stroke. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, scaling to 1374 N push at 0.7 MPa. Unlike the base MBL series, this variant uses a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle to smoothly decelerate the piston, cutting end-cover impact and vibration on faster or heavier moves. The cushion only decelerates near the ends; it is not a load lock or brake.
This SKU includes a CA pivot/clevis back cover that swings on a pin to accommodate arcing or angular loads. It uses a G1/4 port and a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces. Note that this specific model lacks a built-in magnet, so it cannot host a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80CA Is Used
Packaging Line Diverter
Pivots carton routing gates on a packaging conveyor using the CA clevis to handle angular swing, while the cushion absorbs the 881 N retract impact at high speed.
Injection Mold Ejector
Drives a small ejection plate on an injection molding machine, using the 981 N push force and tunable end-deceleration to protect the mold face.
Palletizer Stop Arm
Acts as a stopper arm for incoming pallets, relying on the adjustable air cushion to smoothly halt momentum without slamming the clevis pin.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80CA the Right Cylinder?
If you need less force, step down to the 40 mm bore (628 N push @0.5 MPa); for heavier payloads, step up to the 63 mm bore (1558 N push @0.5 MPa). Choose this MBLC over the fixed-bumper MBL when your cycle rates are high or the moved mass is substantial. For position holding without live air, add an external rod lock, as the air cushion only decelerates and does not lock the rod. Replacement match: 50 mm bore, 80 mm stroke, G1/4 port, PT thread, CA back cover, no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X80CA FAQ
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near stroke end. You adjust it to match your load and speed, reducing impact and noise. It is not a brake and does not hold the load if air pressure is lost.
