Abstract
Downhole centrifugal pumps and related components and methods may include diffusers housing impellers and a rotational shaft passing through the impellers to impart rotation to the impellers. Bearings are positioned within at least some of the diffusers to support the rotational shaft during the rotation of the impellers. Coupling pins may be positioned between and engage with the bearings and the at least some of the diffusers to at least partially secure each of the bearings to one of the at least some of the diffusers.
