When selecting AT/ATB high-precision planetary reducers, there are several considerations to consider:

1. Rated output torque: Determine the required output torque according to the application requirements. Select the appropriate reduction ratio and input speed to ensure that the planetary reducer can provide sufficient torque output.

2. Reduction ratio: The reduction ratio is the ratio between the input speed and the output speed. Select the appropriate reduction ratio according to the required output speed and torque requirements. Generally, a larger reduction ratio can provide higher torque output, but it will reduce the output speed.

3. Accuracy level: Determine the required accuracy level according to the application requirements. High-precision planetary reducers have higher accuracy and repeatability and are suitable for applications with high position and speed requirements. Generally, standard accuracy, precision accuracy and ultra-precision accuracy are available.

4. Output shaft type: Select the appropriate output shaft type according to the application requirements, such as round plane output shaft, smooth hole output shaft, etc. Different output shaft types are suitable for different application scenarios, such as the need to connect to other equipment or transmit power.

5. Maintenance and after-sales service: Understanding the supplier's maintenance and after-sales service capabilities is a factor to be considered during the selection process. Ensure that the supplier can provide timely technical support, maintenance and replacement of parts and other services to ensure the normal operation of the equipment and extend its service life.

Please note that the above are only general selection considerations. In the actual selection process, detailed considerations should be made based on specific application requirements and working environment. It is recommended to consult Rude Transmission's engineers or business personnel before selection to obtain more accurate and detailed suggestions.
