What are the key factors to consider when selecting humanoid robot bearings?

The key factors to consider when selecting humanoid robot bearings are the load, precision and space limitations of different joints; the bearings in humanoid robots will perform repetitive movements, so friction and wear resistance are also key indicators of bearings; during the design phase of the humanoid robot, the future operating temperature and environmental conditions of the robot must also be considered, and self-lubricating bearings, sealed bearings or stainless steel bearings must be selected to meet environmental requirements; in addition, the cost of bearings is also one of the key factors that must be considered, after all, the total quantity of bearings used in each robot is not a few.
