Application scenarios of cross roller bearings in unmanned aerial vehicles

1,Aircraft landing gear.

Unmanned aerial vehicle landing gear needs to withstand harsh environments such as high speed, high temperature, and high load. Cross roller bearings can provide high-precision, high stiffness, and high stability support and transmission, ensuring the stable operation of the equipment.

2,Flight control system.

The drone flight control system requires high-precision motion mechanisms, and cross roller bearings can provide low friction, low inertia, and long-life support and transmission, ensuring the stability and accuracy of the drone in various flight states.

Advantages of Cross Roller Bearings in Drones

3,High precision.

The internal structure design of the cross roller bearing is unique, with rollers arranged in a 90°perpendicular cross arrangement and equipped with isolation blocks, which can effectively avoid an increase in rotational torque and ensure high-precision rotational motion.

4,High rigidity.

Due to the vertical cross arrangement of rollers, cross roller bearings have high rigidity and can withstand loads in all directions, ensuring the stability and accuracy of unmanned aerial vehicles during high-speed operation.

5,High stability.

Cross roller bearings can withstand harsh environments such as high and low temperatures, vacuum, and corrosion, ensuring stable operation of drones in different environments.

6,Space saving.

The inner and outer ring sizes of the cross roller bearings are minimized, especially with ultra-thin structures approaching the limit of miniaturization standards, suitable for unmanned aerial vehicle equipment with limited space.

The cross roller bearing models used for drones include CRBT805 and RA9008:‌

1,CRBT805 is an ultra small cross roller bearing suitable for fields such as automation and drones. Its inner diameter is 8cm, outer diameter is 9.1cm, thickness is 5mm, and weight is 0.05kg. This bearing adopts a double-sided sealing design, with high rigidity and good rotational performance, suitable for the rotating parts of robots.

2,RA9008 is a thin-walled cross bearing that is particularly suitable for fields such as drones, robots, and medical devices. This type of bearing has an ultra-thin structure, suitable for parts that require lightweight and compact design, such as the rotating parts of robots and detection equipment instruments.

In summary, the application of cross roller bearings in drones is mainly reflected in their high precision, high rigidity, and high stability, which are suitable for key parts such as the landing gear and flight control system of drones, ensuring stable operation and efficient work of drones.
