ABSTRACT:
A bearing assembly comprises a pair of relatively rotatable bearing components, where at least a portion of one of the bearing components is journalled to at least a portion of the other one of the bearing components. One of the first bearing component includes an outer, annular journalled surface and the second bearing component includes an inner, annular journalled surface, and one of the outer or inner and inner journalled surfaces include a plurality of recesses disposed there about. Each of the plurality of recesses are filled with an insert formed from a solid, abrasion resistant, self lubricating material; and the insert protrudes outwardly from the recesses, thereby providing a bearing surface for wearing against the other one of the annular journalled surfaces. Preferably, the solid, abrasion resistant, self-lubricating material is a polyamide resin material.
