摘要：
In an embodiment, a bearing assembly may include a support ring to which one or more superhard bearing elements may be mounted. The support ring may include one or more relief features configured to reduce residual stresses in the superhard bearing elements that are induced by brazing the superhard bearing elements to the support ring, operational loads, other processes, or combinations of the foregoing. Reducing the residual stresses in the superhard bearing elements may help prevent damage to the superhard bearing elements. The bearing assembly may be used in subterranean drilling systems and/or other types of systems.
