NewBee Machinery is a professional machinery parts manufacturer providing high quality precision bearings, high-quality non-standard transmission components, and intelligent CNC equipment and more.
NewBee Machinery is a professional machinery parts manufacturer providing high quality precision bearings, high-quality non-standard transmission components, and intelligent CNC equipment and more.
Newbee Transmission's KB/KA series paired thin-wall angular contact ball bearings have been selected for critical stabilization and positioning systems in next-generation aircraft electro-optical pods. These bearings enable precise movement and vibration damping for high-resolution imaging systems operating in extreme aerial environments.
