About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X225U
The AirTAC MBLC50X225U is a double-acting aluminum mini cylinder engineered with a 50 mm bore and a 225 mm stroke. It uses a G1/4 port and a Ø16 hard-chrome carbon-steel rod with an M14x1.5 end thread. Operating at 0.5 MPa, it generates 981 N of push force and 881 N of pull force. The defining feature of this variant is the screw-adjustable pneumatic air cushion at both ends, which allows you to precisely tune end-of-stroke deceleration to match heavier loads or faster cycling speeds, preventing harsh impacts that would otherwise damage the end covers.
This model features a U-type flat-end back cover for rigid inline mounting and lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG electronic position sensors without modification. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over long service intervals. Because the 225 mm stroke combined with the 16 mm rod presents a bending risk under lateral loads, external guiding is recommended to maintain smooth 30-800 mm/s operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X225U Is Used
Bottling Line Diverter
Pushes heavy crates at high cycle rates on a packaging conveyor; the adjustable cushion absorbs the 981 N kinetic energy smoothly to prevent end-cover cracking.
Injection Mold Ejection
Extends 225 mm to eject plastic parts from a press bed, utilizing the rigid U flat-end cover to withstand direct axial impact without back-cover deflection.
Palletizing Push Arm
Transfers cardboard cartons onto wooden pallets, where the riveted aluminum barrel keeps the actuator weight low on the robot arm while handling 881 N pull force.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X225U the Right Cylinder?
If your application requires less force, the 40 mm bore version provides 628 N of push force at 0.5 MPa, making it a lighter, more compact alternative. Conversely, stepping up to the 63 mm bore yields 1558 N of push force at 0.5 MPa for heavier payloads. Choose this MBLC cushioned model over the base MBL bumper type when your cycle speeds or moving masses exceed what a fixed rubber bumper can absorb safely.
The U-type flat-end back cover provides a rigid mounting surface, ideal for straightforward inline pushing. Since this specific SKU does not include an -S magnet, it cannot accommodate a CMSG reed or DMSG solid-state sensor for end-of-stroke confirmation; a separate external limit switch would be required. Furthermore, the air cushion only decelerates the piston near the stroke ends and does not lock the rod—if air pressure is lost, the load will drift, requiring an external pilot-operated check valve for position holding.

- ✓ 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 MBLC50X225U 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 increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. The standard stroke limit for this 50 mm bore is 500 mm, so the 225 mm stroke on this unit is a standard, non-special length.
The cushion is a screw-tunable pneumatic needle at both ends that traps a small amount of exhaust air to decelerate the piston before it hits the end cover. You adjust the needle to match your specific load and speed, which is critical for a 50 mm bore moving heavy masses. It only functions near the stroke ends and does not act as a load lock or brake.
