In the aerospace field, the application of precision bearings is extremely critical because these bearings require high precision, high reliability, and long life under extreme environmental conditions such as high temperature, low temperature, high vacuum, high radiation, etc.

Different types of precision bearings have their own characteristics in aerospace applications. The following are some common types of precision bearings and their application characteristics in the aerospace field:

1. Angular contact ball bearings

characteristic:

Capable of withstanding significant radial and axial loads.

Has high rotational accuracy and speed.

Usually used in pairs to withstand bidirectional axial loads.

Application:

Satellite attitude control: used as an attitude control mechanism for satellites to ensure high precision and rigidity.

Aircraft spindle: used for spindle support of aircraft and helicopters, ensuring high precision and reliability.

Rocket engine: a turbopump used in rocket engines to ensure high speed and precision.

2. Deep groove ball bearings

characteristic:

Suitable for high-speed rotation, capable of withstanding radial and mild axial loads.

Has good rotational accuracy and low friction characteristics.
