Title:
ROLLING-CONTACT BEARING AND METHOD OF FORMING FILM OF LUBRICANT
Document Type and Number:
WIPO Patent Application WO/1997/012156
Kind Code:
A2
Abstract:
A solid film (5) of a fluorine-containing polyurethane polymer is formed on at least one of the constituent elements (inner and outer races (1 and 2), rolling member (3) and retainer (4)) of a rolling-contact bearing (A). The molecules of the solid film (5) of the fluorine-containing polyurethane polymer have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear, the occurrence of the dust can be restricted, and lubrication property can be improved.
