Patent ID: 7938583

Claim:
A corrosion-resistant rolling bearing comprising: an inner bearing ring made of stainless steel; an outer bearing ring made of stainless steel; rolling elements made of a ceramic material; a retainer made of stainless steel, the retainer spacing adjacent rolling elements apart from each other; a solidified lubricating oil sealed in the rolling bearing, said solidified lubricating oil being made by heat-curing a mixture of lubricating oil or lubricating grease and a thermoplastic resin or a thermosetting resin; and contact seals made of fluorine rubber sealing said solidified lubricating oil in the rolling bearing, wherein the solidified lubricating oil is applied to portions of the retainer between the rolling elements so as to wrap the portions, wherein the solidified lubricating oil forms a mass in the space between each pair of adjacent rolling elements and between the inner bearing ring and the outer bearing ring, and each mass has a dimension in an axial direction of the rolling bearing which is substantially larger than a dimension of the mass in a radial direction of the rolling bearing and a dimension of the mass in a circumferential direction of the rolling bearing, wherein the solidified lubricating oil is spaced apart from the inner bearing ring and the outer bearing ring, and wherein the solidified lubricating oil is configured to prevent infiltration of metal abrasion powder onto rolling surfaces of the inner bearing ring and the outer bearing ring.
