In an embodiment, a bearing apparatus comprises a first bearing assembly (202) including a plurality of circumf erentially-spaced first bearing elements (212) each of which includes a first bearing surface (214). The bearing apparatus further includes a second bearing assembly (204) including a plurality of circumf erentially- spaced second bearing elements (224) each of which includes a second bearing surface oriented to engage the first bearing surfaces of the first bearing assembly during operation. At least one of the second bearing elements may be circumf erentially spaced from an adjacent one of the second bearing elements by a lateral spacing greater than a lateral dimension of the at least one of the second bearing elements.
