In nuclear power and hydropower, suitable bearing types include deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, linear bearings, and sliding bearings. The selection of these bearing types should usually consider the following factors: thrust bearings and angular contact bearings are used for bearing thrust loads, ball bearings are usually used for high-speed applications, and roller bearings are used for bearing heavy radial loads.
In nuclear power and hydropower, the technical problems that self-lubricating bearings need to overcome include: 1) corrosion in water environments; 2) Wear issues in aquatic environments; 3) Sealing issues in aquatic environments; 4) The issue of thermal expansion in aquatic environments; 5) Vibration and noise issues in aquatic environments.
